Panasonic today officially released the flagship LUMIX GH4 of its Micro 4/3 mirrorless camera series in Japan, replacing the GH3 that debuted in September 2012. Panasonic GH4 batteryThe new camera is based on the weatherproof and dustproof metal body of the GH3, but has many improvements, making it attractive to both still photography enthusiasts and multimedia videographers. The GH4 features an ultra-high-performance sensor and quad-core processor, which can provide better color interpretation, dynamic range and noise suppression, support 60-minute long exposure with B shutter, and achieve 4K ultra-high resolution video recording. In addition, its autofocus is faster and more accurate, and it also supports eye priority autofocus.

On the official website, Panasonic has released many GH4 photos and videos taken by professional photographers. Although the full resolution is not available yet, the color interpretation seems to be the highest level among LUMIX models. As for the launch information, Panasonic has not yet disclosed the release date and suggested retail price of GH4. It is generally expected that the body price will be around US$2,000, and the release time may be between March and May this year. New sensor + ultra-high-speed quad-core processor GH4 uses a new 16.05 million pixel digital Live MOS sensor, and through the greatly updated ultra-high-speed quad-core Venus processor, it can achieve 50% faster image signal readout than before, not only achieving 30fps 4K ultra-high resolution video recording, but also achieving full resolution 12fps efficiency in static continuous shooting, continuous shooting of 100 JPEG or 40 RAW format images, and continuous autofocus can still maintain a good efficiency of 7.7 frames per second. At the same time, with better noise suppression, ISO 25600 is officially listed as one of the standard sensitivity options (not the original extended setting), and can support B shutter mode exposure for up to 60 minutes. According to Panasonic, the GH4 has also been improved in terms of color interpretation and light and dark levels. In addition, due to the high-speed photosensitive element, the GH4 can significantly improve the jello phenomenon that may cause moving objects to appear distorted when recording dynamic videos or taking photos through the electronic shutter.
However, it should be noted that Panasonic’s official senior management revealed that because the GH4 was designed with great emphasis on internal heat dissipation, it does not have a body anti-shake like the GX7, but the new machine’s better noise suppression ability may make up for this regret.

The world’s first 4K mirrorless interchangeable lens digital cameraThe GH4 is the first mirrorless model that can support 4K video recording, but its 4K video recording is not just an experimental or demonstration-like paper talk, but has extremely complete demonstration-level specifications as soon as it appears. It offers two 4K resolutions: Cinema 4K (1:85:1, 4096×2160) and QFHD (16:9, 3840×2160), with a maximum refresh rate of 24FPS and 30FPS respectively, and two video formats: MOV (supports LPCM uncompressed audio) and MP4 (supports AAC audio), and 100Mbps traffic is encoded in IPB.
For the more basic 1080p video resolution, there is also a 200Mbps ALL-Intra encoding ultra-high traffic mode that can bring extremely clear image quality. In addition, it also supports 2fps, 96fps, 4X and other modes to achieve slow motion and fast motion videos, and can also produce time-lapse photography and stop-motion animation in the body.
Faster, more autofocus points, support for eye focusAccording to Panasonic, the autofocus capability of the GH4 is more advanced than other Panasonic models. Through the newly introduced DFD (Depth from Defocus) technology, the depth of field information of each Panasonic original lens at various aperture focal lengths is used as a calculation reference, further shortening the hesitation time when focusing, and achieving an ultra-high-speed AF of 0.07 seconds. In addition, the focus segmentation area of ​​the GH4 has also been increased from 23 points of the GH3 to 49 points, and the face focus has been strengthened to a more detailed face focus. After finding the face in the picture, the eye area is the clearest range. As for the peak focus required for manual focus, this time the GH4 has of course also been added as expected.

Last month, I took my Nikon D810 out into the Sierra Highlands—one of the toughest adventures. It got dirty, wet, and knocked around a lot. Here’s how it fared. The D810 has strong weather sealing, so it can handle wet or dusty conditions.
DurabilityDurability is arguably one of the most important factors when choosing a camera for adventure photography.
The D810’s body is made entirely of magnesium alloy (magnesium is the lightest structural metal) and is weather-sealed to keep rain and dust out of the camera’s interior. Its shutter is tested for 200,000 cycles, 25% more than the Canon 5D Mk III. All of these features come together to make for a rugged camera.
Nikon D810 Review: The Ultimate Adventure Nikon D810 Camera?
We took the brief but terrifying opportunity to shoot with the D810 in the rain. Photos by Gilberto Gil.
The camera also seems to do a good job of keeping out dust. Upon closer inspection of my photos, only a small dust spot showed up after a month of daily outdoor use and two weeks of intensive High Route shooting—acceptable given the conditions.
All of these factors combined have worked well together; so far, I can confidently shoot with the D810 no matter what difficult conditions I encounter on my adventures. Ease of Use
Nikon D810 Review: The Ultimate Adventure Camera?
The D810 is about twice the size and weight of Sony’s A7-series mirrorless cameras.
First, the D810 is big. The body alone weighs 31 ounces, which is heavy (but still comparable to a Canon 5D Mk III or 5Ds). Add a Nikon 24-70mm f/2.8G ED ($2,499) and the weight reaches 64 ounces, or 4 pounds. That’s too heavy to carry around your neck, in your hands, or, worst of all, in your backpack. Especially if you’re already carrying a lot of outdoor gear.
By comparison, the mirrorless full-frame Sony A7S and 16-35mm f/4 weigh only 34 ounces, or almost half that, and are much easier to handle.
Due to the size and weight of the D810, it’s not a good idea to carry it in the backcountry. Using a standard neck strap is cumbersome; it’s too bulky to use the Peak Design CapturePro clip. The best way I found to carry it was with a Peak Design Slide, but even that isn’t a perfect solution. This problem isn’t unique to the D810, however, but rather a problem with all SLRs; it’s only been highlighted by the recent emergence of more compact but still high-quality mirrorless cameras.
Nikon D810 Review: The Ultimate Adventure Camera?The number of shots remaining is displayed on the LCD screen even when the camera is off.
In my past experience with Nikon cameras, the user interface was a major downfall. It felt clunky, the buttons were hard to reach, and the placement made no sense. However, that’s not the case with the D810. The power switch is located around the shutter button, so you can turn it on and start shooting with just a flick of the wrist. With the default control map, the shutter speed dial is located on the (protruding) handgrip just below the shutter release button; the aperture adjustment dial is on the back of the camera where your thumb would be. The placement of these controls, plus the super-powerful Auto ISO mode, makes shooting in changing lighting conditions feel natural and intuitive.
Some nice touches on the D810 include a display showing the number of shots remaining on the card even when the camera is off, and an Auto Off mode by default. These are unremarkable but useful features. Shooting starts within half a second of turning the camera back on, allowing photographers to capture the briefest of moments.
The D810’s impressive dynamic range allows it to preserve detail in both highlights and shadows, even in challenging lighting conditions and environments – such as on snow. ISO 64, f/4.5, 1/160.
Speaking of capturing fleeting moments, the D810 borrows the renowned focus system from the top-of-the-line D4S, which features a 51-point Dynamic AF mode with 3D Tracking. Combined with a focus sensitivity of -2 to 19 EV, the camera locks onto subjects quickly and without hesitation, even in dark shooting conditions. When shooting on the highway, the D810 focused so quickly and quietly that I often didn’t even realize it had focused. The very fast and accurate focus system, combined with the respectable continuous shooting speed, makes it easy for the D810 to capture fleeting moments.

10.8V 2500mAh Nikon EN-EL18C Long Life Battery Replacement

For my final batch of photos with my Nikon D4S, I decided to do some documentary-like photography around Greenwich Village. I purposely chose to shoot from dusk to evening to test the camera’s amazing high ISO capabilities.
I started in Hudson River Park, where I found a beautiful flower bed—but it was in the shade and very windy. It was 7 pm and still bright, but the situation required quite a bit of sensitivity. I needed to set a narrow aperture of f/8.0 to get enough depth of field and use a fast shutter speed of 1/320 second to freeze the flowers being blown by the wind. To achieve this, I had to crank up the sensitivity of my Nikon D4S to an equivalent of ISO 1250. As you can see in the image above, the resulting image is almost completely free of noise. It has the smooth tones and rich color saturation that you would have expected from shooting with the camera at ISO 100 or 200 a few years ago.
I stayed in the park until dusk, then wandered onto the jogger and bike path. At this point, the light had dropped to about EV 7 (ISO 100), which meant I had to use ISO 6400 to get an action-stopping shutter speed of 1/500 second with the aperture set to f/4.0. The Nikon D4S’s autofocus system had no problem tracking the cyclists and

roller skaters in the dim light. Noise was noticeable in the images at this higher sensitivity, but they still retained a good amount of detail and color. As dusk turned to night, I left the park and began a stroll through Greenwich Village. With the Nikon D4S Replacement Camera Batteryset to Auto ISO, I shot a series of portraits of people walking on the street and sitting inside and outside restaurants. The D4S’s sensitivity climbs from ISO 14,400 equivalent all the way up to an amazing ISO 229,880.
I got one of my favorite images of a couple of musicians and a dancer at dusk in Washington Square Park, shot at 1/125, f/4.0, and ISO 28,735. There is definitely noise in the image when viewed at 100% magnification, but color is preserved fairly well, and at smaller magnifications the image looks fairly clean.

To test the video capabilities of the Nikon D4S, I took it to Tompkins Square Park one evening. I wanted to experiment with the extremely shallow depth of field that the camera’s full-frame sensor can achieve when paired with the AF-S 50mm f/1.4 lens. I set up the shot to focus on some flowers in the foreground, then shifted focus to people walking by in the background, and shot several clips using a shutter speed of 1/125 with apertures ranging from f/1.6 to f/2.8.

I found it very easy to compose my shots on the LCD and check exposure with a quick test clip. I had some trouble focusing accurately at normal magnification using the Nikon D4S’s LCD monitor, but I solved that problem by increasing the live view magnification to enable critical focus at the press of a button. While I kept the sensitivity at ISO 200 equivalent for the best footage, you can record movies in manual exposure mode using Auto ISO. This is undoubtedly useful in certain news and documentary shooting scenarios where light may change while shooting.
ConclusionIf there is one fundamental difference between professional cameras and amateur and enthusiast cameras, it is this. A professional camera is designed with the idea that you can rely on it to shoot no matter what. It has the versatility and performance to shoot weddings, car races, and keep shooting through storms, riots, and hard landings on dirt airports.
I haven’t gotten in trouble with the Nikon D4S, so I can only make an educated guess about its durability based on its rugged construction. However, its versatility and performance are unmatched by any other camera I have ever used.
Of course, the D4S has far more features than most of us (including me) need. (Personally, I find it too expensive and too bulky.) Still, I find it very enjoyable and satisfying to use such a responsive, well-made precision tool. That might be a reason to buy one – even if you’re not getting paid to shoot every possible situation and take award-winning photos.

Sure, the Arlo Pro 2 has 1080p HD video, infrared night vision, and two-way audio, but is it worth the price? The Arlo Pro 2 is a high-quality outdoor camera that features 1080p HD video, infrared night vision, and two-way audio. We also like that it comes with a siren, which does a great job of scaring off potential intruders. Outdoor video security is just as important, if not more important, than indoor video security. Wouldn’t you like to catch snoopers sneaking out the door before an intrusion occurs? Or wouldn’t you like to know who’s at your door before you open it?
In this review, I’ll answer some questions and provide details about the Arlo Pro 2, one of Arlo’s battery-powered, weatherproof outdoor cameras. It’s one of the few affordable wireless cameras I’ve found that can run completely wirelessly, and to help you decide if it’s the right choice for you, I took the liberty of testing it in my own home. My standards are high, so hopefully the Arlo Pro 2 won’t disappoint. My Arlo Pro 2 review begins now! Although the Arlo Pro 2 is no longer available, there are still a lot of things to learn from our experience with it, especially if you’re planning to buy a new camera from Arlo.
I’m happy to say that the Arlo Pro 2 setup is very simple and straightforward.
I downloaded the app on my iPhone X (it’s also available for Android, by the way). I plugged the hub into the internet using an Ethernet cable, pressed all the sync buttons, and waited for each device to connect.
I’d say the setup took me about 15 minutes, from downloading, syncing, and getting used to the app, which isn’t bad. I must warn you, though: make sure you have a strong Wi-Fi signal before setting up this camera. I can’t tell you how frustrating it is to set up a device like this when the network is spotty. These things require the four arcs on the Wi-Fi icon that we all love.
In short, make sure your router is ready to provide a great installation experience. Essential FeaturesGreat! Now that we’ve got everything assembled, it’s time to test these cameras – essential features, of course.
At Security.org, we’ve seen a lot of cameras. We’ve figured out what makes a camera a strong competitor in the market and a satisfying product to have in your home. We looked for cameras with high-quality video, audio, night vision, smart platform integrations, AI, convenience, and value.
Does the Arlo Pro 2 hold up in the test? Let’s find out! I really liked the Arlo Pro 2’s crisp video, and I know that’s because this baby camera records in 1080p HD resolution. These days, 1080p is the industry standard, so this camera is on par with the competition. I always look at night vision quality when I evaluate cameras because it’s important for us to know if a camera is good at recording things in the dark. Most of the things we fear most—robberies, burglaries, vandalism—happen when we’re asleep or in places where we simply can’t see. To feel safe, we need to have quality night vision.
Now, the Arlo Pro 2 does have a night mode that I like, which uses infrared lighting instead of white light. Some cameras use white light, and while white light can take good pictures, I find the harsh light very distracting and easy for an intruder to spot. Infrared lighting is more discreet and just as effective in some situations. The two-way audio feature on the Arlo 2 is excellent.
The reason I love two-way audio so much is because it enhances your ability to communicate with the people in your life. Let’s say you’re in the kitchen and want to talk to your kid in the bedroom, you can just tap on the app and speak through your phone. That’s awesome, right?Once you click on settings, you can turn off the camera for privacy or change the video settings. In the menu, there are options like “Best Video,” “Optimize,” and “Best Battery Life” to choose from. I think Arlo made these options a smart choice since these cameras are wireless. If you don’t want to frequently charge the camera’sArlo Pro 2 battery you can make the battery last longer.
Finally, the Library button takes you to all motion- and sound-activated recorded events so you can see exactly what’s going on in your home. If you tap on the “Mode” tab, it takes you to the central settings where you can enable or disable the system, schedule alerts, and turn on geo-fencing. Hidden features?I love the wireless capabilities of the Arlo Pro 2 because it means there are no extra wires around the house for my cats to play with or chew on. But it turns out that I miss out on features like uninterrupted continuous recording, the ability to designate motion/activity zones, and 3-second replay when my camera isn’t plugged in.
Non-stop continuous recording is self-explanatory – you can choose to have the camera start indefinitely when the camera is plugged into a power source. Motion/activity zones allow you to specify important parts of the area to record, such as windows or cribs. This will allow for more specific notifications.
After exploring everything, I think the Arlo app is pretty comprehensive. It’s pretty simple, but I can see how people can easily get lost in the dashboard – it’s quite hard on the eyes. But once you get the hang of it, I think the app is pretty good.
At Security.org, we look for cameras with two storage options for a number of reasons. We like the cloud option so that we don’t have to worry about running out of space on our SD cards and hard drives. On the other hand, we like the local storage option as a backup in case something goes wrong with the server. Since some people are reluctant to store information on a private cloud, having both local and cloud storage options is a necessity.
Thankfully, the Arlo Pro 2 has both options. I can connect my hub directly to the hard drive and download the memory from there, or I can also access past recordings through my app. Arlo offers seven days of free cloud storage, which is pretty Generous. I’ve seen many companies only offer 24 hours of free storage.

Rather than shrinking the size of one of its single-lens translucent (SLT) models, as Canon did with its SL1 compact DSLR (which would likely result in a more expensive model), Sony has adopted a seamless design around its E-mount. Mirrorless DSLR style body. Lens and NEX menu and control system. Overall, the idea makes sense. Once you put down the mirror, the biggest limit to zooming out becomes the lens mount. On paper (though not necessarily in practice), the NEX menu system looks friendlier to novice buyers of this camera. As you can see, the A3000’s closest price competitors, such as the Canon T3, are generally around two years old. Unfortunately, the result is a very confusing camera. Since it has to be on the website somewhere, Sony hid it in the middle of the SLR page, which in itself is misleading since SLT cameras are not SLRs. The truth is, there are two main reasons people upgrade from point-and-shoot cameras: better photo quality and better performance. The A3000 succeeds in the first, but not in the second. For the most part, the ability to change lenses tends to be an ancillary desire—most people stick with the lenses that come bundled with their cameras. Unlike compact DSLRs like the Canon SL1, Sony’s use of the E-mount system means the lenses are smaller compared to full-size EF-S lenses.

Picture qualityThat’s one thing the camera really does; it really is the best image quality you can get for $400 right now. It delivers very good JPEG images in the ISO 800 range and relatively usable JPEG files in the ISO 1600 range, depending on the image content You can even live with ISO 3200 if you’re upgrading from a point-and-shoot. Image processing is pretty good, but if you shoot raw+JPEG and process raw you’ll probably get slightly better results; you’ll get more detail, but only in exchange for a Granier image.
Sony Alpha A3000 Photo Sample The tonal range is pretty typical for an entry-level APS-C model, in that it clips highlights and doesn’t retain much detail to render, Battery for Sony Alpha A3000 but it recovers shadow detail without adding a lot of noise. Colors are saturated and contrasty, with some tonal variation in the reds, but they’re still pleasant. There’s no neutral color profile option; you can adjust existing presets, but you can’t save them as new ones. Videos also look good for the class Yes, it’s a bit washed out and there are aliasing artifacts (aliasing) on ​​the diagonal or film edges, but the detail resolution is decent. As you’d expect, artifacts increase as ISO sensitivity increases, but overall, I thought the video quality was adequate for vacation, school, and other casual use.
PerformanceThe A3000 may look like a DSLR and produce images similar to a DSLR, but it doesn’t shoot like a DSLR. This is partly due to its use of an old-school contrast AF system (rather than the new hybrid AF system found in Sony’s higher-end NEX models, or the fast phase-detection AF found in true DSLRs) and relatively slow processing speeds. The HX300 is generally faster even at its wide zoom range.
Power-up, focus, and shooting take just 1.9 seconds; it’s slower than the similarly priced Panasonic Lumix DMC-GF5 mirrorless ILC since it has been replaced, and significantly slower than competing dSLRs. Focusing and shooting takes 0.5 seconds in good light and 0.8 seconds in dim conditions. This requires abDesign and featuresThe A3000 is lighter than a dSLR but significantly heavier than the more compact ILC, and the best aspects of its design are the relatively large handle, the large stereo microphone, and the placement of the memory card slot on the left side rather than in the battery compartment. There’s a hot shoe on top, a rare feature at this price, buttons to switch between the viewfinder and LCD, a mode dial with the usual manual, semi-manual and automatic modes (there are actually two Auto modes, automatic and more automatic) plus panorama and play buttons. I have to say: You really won’t appreciate the eye sensors on higher-end models unless you’re forced to switch manually.
On the back is the EVF, a large, well-placed movie record button, a very smooth rubber-free thumb rest, and NEX-like controls. The latter includes ISO sensitivity, drive modes, exposure compensation and display options, although these are all reprogrammable. The two buttons above and below the adjustment dial are context-sensitive and display soft labels on the LCD screen.
However The NEX menu system is deceptively complex. Although it’s divided into large, friendly categories at the top level, once you get to another level it can be difficult to quickly find the setting you’re looking for., it does remember your last position in each submenu, which is nice. The camera has a reasonable, but unexceptional feature set for the money. It’s got the boring filter selection from older NEX models and only does 60i or 24p in real HD. It does support manual controls while shooting video , and in fact lets you set the shutter speed to anything you want, which can be nice for special effects — most cameras stop you at 1/30 second.

A few years ago Pentax may have been the UK’s leading supplier of advanced amateur and semi-professional cameras, but over the following years their position has declined. Pretty much the last legacy brand to go digital with the awfully named *istD, they then did minor upgrades with Ls and Ss suffixes. But recently, everything has changed and K is back! First there was the K100D with the new Anti-Shake (AS) device and now the K10D with AS and a host of new features is aimed not only at advanced amateurs but also semi-professionals.

Historically, all cameras worth their salt have had PASM, which stands for Program, Aperture Priority, Shutter Priority, and Manual. Pentax has gone a step further with this camera, which I call PASIM because they added a very reasonable ISO priority setting. Pentax calls it sensitivity priority, but we usually know it as changing the ISO setting. In fact, there are two versions of sensitivity mode, one that chooses shutter and aperture for you, and another called Shutter and Aperture mode that allows you to choose shutter and aperture while optimizing the ISO for you.
The next big advancement was the image processing engine. Called PRIME (Pentax Real IMaging Engine), it collects data from sensors in 22-bit format and then A/D converts it to 12-bit RAW or 8-bit JPEG for storage. Pentax claims better graduation results with this system. DDR memory is used to keep image processing and data transfer as fast as possible.
AS and dust removal are interrelated, as the sensor features a nanotechnology-based fluorine seal to prevent dust settling, an adhesive strip to collect particles, and a combined vibration function to remove stubborn particles such as pollen. AS is said to allow the lens to improve independently by up to four stops when held handheld. (PEF) RAW and the Adobe Universal RAW format DNG RAW. JPEGs can be shot in three sizes (10, 6 and 2 megapixels) and in three qualities (three stars, two stars or one star). The camera also supports SDHC compatible cards, offering higher capacities.

The menu system will be familiar to anyone upgrading from an early Pentax DSLR, and is simple to navigate for those new to the system. The secondary menu, accessed by pressing the Fn button on the right side of the rear screen below the daisy wheel, common displays changes such as shooting mode, white balance, flash and ISO settings. White balance is adjustable between automatic, six presets, manual and Kelvin scale. Shutter options include single shot, continuous shot, 12-second timer, 2-second timer, IR remote, and IR remote with 3-second delay. ISO can be set from 100 to 1600 in 1/3 or 1/3 stop increments, and the flash has five different modes and compensation from –2 to +1 stop, also in 1/3 or 1/3 stop increments. quantity.
A switch on the side of the K-AF2 lens mount allows single, continuous or manual focus selection, and the AF area can be set to automatic, selectable or center point via a knurled ring around a rocker-type daisy wheel. Select the metering mode via the auxiliary ring below the mode dial. Built with a stainless steel chassis, the K10D has a total of 72 individual seals mounted on its fiber-reinforced polycarbonate (FRP) body, making it dust and rain-resistant with a durable finish. It also feels well-made, without any pretense of light weight or small size. It’s not that the camera is too big or too heavy, it’s just right. Whether you have large hands or the more delicate version, it’s comfortable to hold, with plenty of space between the grip and lens mount for the clumsiest of fingers.
The shutter release is located at the top of the handle, and two adjustment wheels drop easily onto your thumb and forefinger. To the right of the top of the camera is an LCD screen that displays all shooting parameters as well as an estimate of the number of frames available on the SD memory card. On the left side of the prism housing, the main mode dial has a secondary lower ring that controls the metering mode. The prism housing itself contains a pop-up flash unit with a guide number of 11 , which is convenient but not overly functional, as well as a hot shoe. The controls on the rear of the camera are well laid out and bear a strong kinship with its younger siblings, but with a few extra features added to bolster its credentials. These include a ribbed ring around the rocker for selecting focus modes, a handy addition that has been removed from the menu. The K10D has a Pentax  K10D Camera Battery  grip that can be purchased as an extra, but it’s worth mentioning here. It’s one of the most comfortable grips out there, and it’s built just as well as the camera, with a similar seal. However, it does have one quirk. The handle only holds one battery, the original camera battery remains inside the camera. This does mean that to charge the first battery, the handle needs to be removed. On the plus side, the extra space in the handle can be used to accommodate a spare card holder. 

Flash optionsA pop-up flash is a handy piece of gear on any camera, especially for fill-light work rather than lighting the entire scene, and in this case it’s well thought out. The Function (Fn) button in the lower right corner of the home screen displays the usual secondary menu, one of the four options being flash settings. You can choose from Flash On, Flash On + Red Eye, Slow Sync, Slow Sync + Red Eye, and Rear Curtain Sync. With the screen on, you can use the rear thumbwheel to adjust flash compensation in ½ or 1/3 stop increments from –2 to +1 stop. The whole thing is very intuitive.
performanceWith a choice of two RAW, RAW + JPEG, or nine sizes/quality JPEG recording formats, the choice is almost confusing when it comes to storing your images. While three sizes and three qualities of JPEG are now common, Pentax unusually gives you the option to record RAW files in its own PEF format or Adobe’s universal DNG format. The included software Pentax Photo Lab supports both file types and is pretty good for free software.
Autofocus speed appears to be limited only by the lens, and since the camera is designed to operate with an upcoming sonic motor lens that Pentax is developing, it will be interesting to see how fast the system is.

At default settings, the camera produces files in JPEG format that are pleasantly colored and not oversaturated, and settings can be configured via the menus to achieve any desired amount of correction in image hue, saturation, contrast, or sharpness.digital noiseISO settings range from 100-1600, and the camera has a noise reduction setting that works at all speeds. While it does make some subtle differences at high ISO, this can be done much better with a dedicated software package. Regardless, files shot at speeds up to ISO800 are very useful, and the ability to select sensitivity speeds in half- or third-stop increments gives a lot of leeway. Metering is via 16-zone multi-segment, center-weighted or spot metering, selected via the secondary dial below the mode dial. It proved to be quite accurate, selecting the correct exposure for all scenes attempted.The 2.5-inch rear LCD screen proved bright and visible at fairly wide angles, and the 210,000-pixel display was more than adequate for the job. When viewing pictures, you can use the rear thumbwheel to zoom in, making the operation simple and fast .

The dedicated lithium-ion Pentax K10D Camera Battery proved to be very long-lasting, recharging within an hour at three-quarters of a charge, after a day of shooting with a lot of menu clutter. Stuff, some onboard flash for photos and a dedicated Pentax flash, and a lot of image removal to achieve this.

Surprisingly, Sony has remained unchallenged in this segment for over two years, during which time it has successfully launched two more generations of the RX100. The Sony RX100 III features an electronic viewfinder and a more consistently bright (albeit shorter) zoom, helping it further outshine its rivals. With the arrival of the Canon PowerShot G7 X, this largely unchallenged supremacy comes to an end.

Like the RX100 III, the G7 X offers a 1-inch 20MP BSI sensor matched to an F1.8-2.8 zoom (from 24mm equivalent focal length). The two cameras are also similar in size and offer broadly similar feature sets. This is great for photographers, because it means Sony finally has some proper competition. Canon is one of the only manufacturers to have consistently offered dedicated enthusiast-level compact cameras in its lineup, and the arrival of the G7 X means it now offers four: the S120 , G16, G7 Each offers a different balance between size, price, and functionality. The G7 X’s styling and dimensions make it look like an S-Series, but the level of direct control justifies its G-Series moniker.

The camera’s combination of a touchscreen, a dedicated exposure compensation dial, and a click control dial around the lens provide a high degree of direct control for such a small camera, and Canon’s iterative, evolutionary approach to camera interfaces, as well as spending a little time playing with the camera, suggests it should work just fine.
At the same time, judging from the details of the sensor, it uses Sony’s IMX183CQJ sensor, so it is completely comparable to the latest RX100 series in terms of image quality. This alone is enough to make it a great addition to the market. G7 X is just as small as the Sony but offers more in terms of direct control.

lensGiven that image quality depends on light capture, the best way to get the most out of a large sensor is to pair it with a bright lens. One of the factors that helped the RX100 III win the gold medal was the inclusion of an F1. 8-2.8 zoom feature, which means the camera can retain more of the big sensor advantage as you zoom in (rather than killing it with F4.9) over the first two RX100s maximum aperture at telephoto). However, this increase in speed comes at the expense of lens range, with Sony limiting the zoom range to 24-70mm equivalent to keep the camera small.

So it’s interesting that Canon has packed a 24-100mm equivalent lens into the G7 X, while also offering a maximum aperture range of F1.8-2.8. And, to paraphrase some nasty internet verbiage: We looked at the G7 Wide aperture combined. Zoom range while reducing camera size. Note in the image above that the G7 X’s maximum aperture stays bright much longer than the RX100 III’s. They may offer the same range on paper, but at any point between 24-50mm equivalent focal lengths, the Canon’s lens can maintain a wider aperture than the Sony’s, and at 30mm equivalent focal lengths, the difference amounts to 2/ 3EV and above.

The image above should make it clear that the G7 consistently X is one of the most bright compact cameras on the market once sensor size is taken into account, which should allow for excellent control over depth of field (including the focal length for shooting). classic portraiture) and low-light performance. Considering that both cameras are likely to use the same (excellent) sensor, if the Canon’s lens is good enough, it’s reasonable to expect that the Canon’s image quality will be quite competitive.

Only Panasonic’s DMC-LX100 offers more light-capturing power, and it’s a larger camera with a tighter zoom range (although we also think this is very attractive, depending on your specific needs and taste).
Specification comparisonSize, sensor, lens specs and price make the Sony RX100 series the G7 X’s most obvious competitors, but we think the G1 X II should also have cause for concern.

The big G offers a slightly longer zoom and the ability to add an electronic viewfinder , but the G7 X is much smaller, slightly cheaper, and rivals it in terms of direct controls. In its bid for the RX100 crown, the G7 X risks eclipsing Canon’s existing champion. To be clear, it’s not all plain sailing for the G7 X. Video shooting with the Sony RX100 III is excellent, and there’s nothing in the G7 X’s specs or in Canon’s recent compact camera history to suggest it can match the Sony in this regard. The addictive clickless control dial on the Sony is certainly useful when video footage. Canon PowerShot G7 X longevity is also pretty bad.

The G7 X also doesn’t have the option to include a viewfinder, whereas the RX100 III has a built-in viewfinder. This may be a deciding factor for some shooting photographers, but the Canon is brighter, has a longer lens and has better external control range
