The Good. The question is, what's not good? The A7R III is basically the A7R II on steroids. Sony has pumped it with major upgrades, plus a couple of new features you might find in the pro-level A9, making it one of the most incredible, top performing cameras in the market today. It boasts a 42.2 MP full-frame Exmore R CMOS sensor with excellent dynamic range coupled with a mind-blowing AF system and 10fps burst shooting to mention just a few main features, all packaged in a sleek body that's easy on the eyes and in your hands. Other crowd-pleasers include its 5-axis IS system, 3.69M dot OLED EVF and dual SD card slots with one UHS-II support. And did we mention it also carries Sony's new Pixel Shift feature? 

The Bad. If we must nitpick, there are a few things that could be better. The ISO sensitivity is still at 50 (compared to competitor Nikon D850's ISO 32), subject tracking could use a bit of work, and the rear tilt-angle display could be more utilitarian--its limited angles and touchscreen functionality might be underwhelming to LCD-oriented users. Plus, it might be nice to have two UHS-II slots, and card-writing lags will cause delay and make you miss some shots. But ultimately, it's one of the best and most well-balanced cameras you'll ever handle especially at that price.

The Bottom Line. If you haven't gotten your hands on the Sony Alpha A7R III yet, then gird your loins. Released only in November of last year, this beautiful beast is already much beloved due to its excellent performance, super high resolution, impressive dynamic range and other features you might find in more expensive models. 

Pick This Up If... you're a photographer (period!) The A7R III's carefully picked roster of top-tier features gives it that edge that caters to many types of photographers' needs. We're not saying you need to swap out your current system that you've spent thousands of dollars in... but maybe you should.

INTRO

The A7R III came on the scene to rattle cages it seems, boldly competing with the likes of Nikon's D850 and Canon's 5D Mark IV, which had already established themselves as indomitable forces, and sealing Sony's fate as a powerhouse in the camera world.

DSC00478.jpg

It's not perfect, obviously--it has a few design quirks that could use a bit of work, but what camera doesn't? Is A7R III worth all that hype? Absolutely! This full-frame mirrorless takes the weaknesses of its predecessor and draws inspiration from the faster, higher-end A9.

It is a brilliant mix of performance, speed, and resolution, with a 15-stop dynamic range to make it such a forgiving camera, 399 phase detection AF points and 425 contrast AF points to give it more precision and more reliability even in low light situations, and a small body to make it lighter to lug around. 

GEAR USED

BUILD QUALITY & DESIGN

The A7R III features a magnesium alloy casing, six screws to secure the lens mount, and lightweight body hovering around 1.3 lbs compared to the D850's 2 lbs. With sealing throughout the body to include its buttons and dials, this camera is really built to last and withstand typical camera stressors such as dust, moisture and, well, heavy use. 

DSCF1099.jpg
Bear in mind, however, that while it might do well shooting in the desert on a normal, breezy day, it's only weather-sealed, not weatherproof. That means that it might not survive a dirt bike race or off-roading or a really windy day on the sand dunes. Of course, we haven't actually tested it in extreme situations, but at $3,198 a pop, would you want to risk it?

DSCF1104.jpg
As far as the design, think of it as the missing link between the A7R II and the A9. It has the look and feel of its predecessor, albeit just a tad thicker, but it also carries a few of the features people love about the A9. That includes a better front grip, a multi-selector joystick (extremely useful when adjusting focus area quickly), an AF-ON button, a monitor that supports touch control, and an electronic viewfinder that boasts a 3686k-dot resolution that allows more detail and a higher refresh rate. 

Delving in deeper, you'll also notice that much like the A9, the A7R III also boasts a dual SD card slot with one slot for the faster UHS-II, a longer battery life at 650 shots per charge, and compatibility with the Sony VG-C3EM vertical battery grip for even longer use and for shooting videos.

The lens release button is a tad stiff, at least when new, and you would have to apply a bit more force to release the lens, which can get in your way when needing to switch lenses quickly. But we do love the noticeable tactile response of its dials so it's harder to inadvertently turn one, forgoing the need for a lock button. And when you do, you will know that you did, alerting you to any accidental change in settings.

ERGONOMICS

The handling and user-friendliness of the A7R III has always received mixed reviews. First of all, it's size. On one hand, it's lighter, takes up less space, easy to tuck out of the way, and a perfect fit for those with small to medium sized hands. On the other, it might be a little too compact for bigger or gloved hands and bigger lenses. These aren't that big of a disadvantage, however, and don't affect the camera's overall performance.

DSCF1109.jpg
Secondly, there's the accessibility of its functions. Non-Sony users might find that some of the button positioning, as well as the main menu, can take some getting used to. The menu button, for example, is placed on the top left section instead of the right-hand side, and the menu itself is not only comprehensive but also has the tendency to bury options that should be easily accessible.

The good news is that it only takes a few test runs to get used to the menu once you understand how its system works. Sony added a color coding feature to make it easier for users to recognize what tab they're under. The camera also boasts three custom buttons, a customizable Function Menu to quickly access 12 options, and a sixth tab called My Menu that is also customizable. 

With the help of these, plus the "Recall Custom Hold," which lets you set presets, any user can personalize the A7R III and really make it their own. Plus, they simply reduce the need to access the camera's complex menu.

Another thing that people have mixed feelings about is the touchscreen function, which is solely for adjusting focus. It's useful on some level, but we cannot say for sure that it's even absolutely necessary. Not when you're used to the old ways and not with the joystick there, which is frankly far more convenient to use. If a manufacturer is adding the touch function anyway, why not expand it to navigate the menu and make selections?

One thing we really appreciate though is the Function button, which moonlights as the Send to Smartphone button when in View mode. The A7R III may not have a dedicated Wireless button, but through this, you can send photos to your phone without much fuss.

MENUS & DISPLAYS

As we mentioned in the previous section, A7R III isn't exactly the easiest to navigate or search through. The five tabs that make up the whole menu have multiple pages, and each page has a number of options. This is true of Sony's menu system in general. It does take some getting used to, and it'll take a lot of digging through at first.

Sony is seemingly aware of this situation and has taken steps to remedy it, though not by changing the system itself but indirectly.

DSCF1110.jpg
First, of course, is with its new color coding, assigning a different color to each of the six tabs and highlighting the bottom part of each tab with its respective color. By switching the highlighted portion from bottom to top, it essentially tells you which tab you're on. It's a modest attempt that is, to an extent, helpful.

Again, as we mention in the previous section, Sony also offers the three custom buttons, the My Menu tab and the Function Menu that make a world of difference once set and personalized.

DSCF1131.jpg
Users will definitely get a lot of use out of the Function Menu, which is quickly accessed with the small Fn button above the control wheel. Basically, it acts as a quick menu, giving you access to certain settings--12, to be exact--without having to dive into the complicated menu every single time. All you need to do is assign the spots; preferably to those options you constantly use or would like quick access to.

The My Menu, which is the sixth tab on the Main Menu, is not as quickly accessible. But it's still very useful, especially for any Function Menu overflow.

SPEED & AF PERFORMANCE

DSC00001-2.jpg
One of the best things about the A7R III is its impressively fast and extremely accurate autofocus system. Like its predecessor, it keeps the 399 on-sensor phase-detection AF points, which is already very precise when locking onto subjects. However, to boost the system, Sony adds 425 contrast-detection AF points. That's 400 more points compared to the A7R II. 

It's not as high as A9's head-spinning 693 phase-detection AF points, which covers 93% of the frame. But still, A7R III's Fast Hybrid AF system enhances its autofocus speed that works so well even in low light situations as dark as -3EV. Couple it with the camera's Eye AF or Face Priority in AF, which is similar to A9's algorithms, at AF-C, and you've got a lean, mean subject-tracking machine.

It's by no means perfect. During our tests, when shooting in burst mode to shoot a fairly fast moving subject--a person spinning in place, for example--the camera would sometimes lose focus of the subject's face when his/her face is turned away from the camera. Its face detection capability sometimes gets a little erratic when the subject's face isn't completely visible, for example when the subject is wearing sunglasses.

DSC00146.jpg

However, compared to other cameras--we tested it alongside a different manufacturer's newest flagship (more on that soon so keep an eye out)--the A7R III's autofocus will simply blow your mind. It definitely makes it easy for photographers shooting scenarios with a higher demand for continuous AF.

Complementing this fast and precise AF system is its whopping burst rate that tops at 10fps, thanks to its Exmor R CMOS sensor and BIONZ X image processor. True, that's only half the speed of A9's sports photography-focused 20fps. And even with a UHS-II card in the slot, slower write speeds can sometimes get in the way. That is, it mostly just prevents you from reviewing your shots instantly.

But A7R III is not designed as a sports camera, and its combination of superior AF performance and fast continuous shooting still put it at the top of the list for most typical and many high-demand shooting scenarios. In fact, it's lead on other cameras in terms of speed and shooting accuracy is so glaring you'll actually experience withdrawals when you're using other (even newer) models that are meant to compete with it.

METERING 

A7R III's metering is unchanged with 1,200-zone evaluative and -3 to -20 EV sensitivity. It features six metering modes: Multi-segment, Center-weighted, Spot, Spot standard/large, Entire screen average and Highlight. 

The metering is highly accurate, especially when you're using Multi-segment mode, which is great for most situations, with the exception of high-contrast scenes. For these, Highlight performs much better in preventing highlighted areas from being overblown.

DSC00042-2.jpg
It's worth noting, however, that while switching metering modes, depending on what the scene calls for, is great practice, the A7R III's incredible 15-stop dynamic range helps a great deal. Even if you forget to switch to Highlight mode in high-contrast situations, the camera is very forgiving and you'll still get an ok shot--with most of the details preserved--that you can later tweak in post. It's almost miraculous.

STILL IMAGE QUALITY 

DSC00310.jpg
Armed with the 42.2 MP full-frame Exmor CMOS Image Sensor, the evolved BIONZ X image processing engine and extended dynamic range, Sony delivers as promised. It's highly forgiving while still delivering the finest detail reproduction and great noise reduction. 

Some degree of chromatic noise and unnatural, exaggerated smoothing may already be discerned at 8,000 ISO, but it still does a great job in keeping those issues at bay so that at 40,000, you'll still get a highly usable shot. More on that in the next section.

Alongside its 5-axis image stabilization, which allows users to shoot at slow shutter speeds handheld and achieve still good results especially when using the electronic shutter, this beast delivers sharp, highly detailed images with beautiful, more accurate color rendering, better tonal range, and well-controlled noise.

It's so good, in fact, that it might just make the most inexperienced user look like a proper photographer. 

One thing worth mentioning is Sony's latest Pixel Shift Multi Shooting function, which the A7R III carries. The new feature essentially allows users to get a super hi-res still image with even finer details, more realistic color reproduction and reduced moire by taking four pixel-shifted shots and weaving them together in one composite.

DSCF1136.jpg
DSCF1141.jpg
This feature takes a bit of work as the camera itself doesn't perform the merging (you have to use Sony's Imaging Edge Software), and you have to use a tripod to shoot the images. But it's worth it if you want sharper images and need to squeeze in as much detail as you can in your photos. The only thing is, it doesn't quite work as well with scenes with many moving parts.

Check our Sample Image Gallery for our Pixel Shift Multi Shooting samples.

ISO PERFORMANCE 

With an impressive sensitivity range of 100 to 32,000 (expandable: 50 to 102,400) for still images, the A7R III is more than equipped to handle extreme situations that demand ultra-high sensitivity for faster speeds. Of course, it's always better to exhaust all other options first before resorting to using extremely high ISOs, but it's always good to have those handy if you really need them.

Keep in mind that while it does manage noise factor well, the higher ISOs do exhibit noticeable chromatic and luminance noise. These start becoming visible beyond 6,400, though you'll see hints at 3,200 if you look really closely. That said, we found that it kept color noise to a manageable level even at 51,200.

DSC00048-2.jpg
In an effort to control grain, we did find some exaggerated smoothing and sharpening at higher ISOs, even at 6,400. But that isn't as distracting until you've hit the 5-digits, and even then the untrained will barely notice.

VIDEO QUALITY

With three file formats--including 4K (3840 × 2160 pixels) at 30p and 24p as well as HD at 120p, 60p, 30p and 24p--video capture options abound for videographers both amateur and pro. Supporting that are a built-in stereo microphone and microphone and audio monitoring ports, plus eight picture effects and several creative styles, if those float your boat. 


Unlike its predecessor, the AR7 III boasts the Gamma Display Assist and SLOG 3 to squeeze in as much detail in highlights. Its 5-axis image stabilization is quite effective, helping users create smooth videos for handheld situations. It also handles low light situations nicely at high ISOs of up to 12,800 with very minimal color shifts and well-controlled noise.

We found that it produces crisp and very clean videos, boasting very fine details on both 4K and Super 35, with the Super 35 offering even better details. The autofocus works extremely well, too. Switching focus from one subject to another with AF-C is beautifully smooth, not erratic, making for more natural transitions, even with fairly fast-moving subjects.

One feature that is very useful is the screen. It's less reflective with less dimming and enough contrast to ensure that you can see enough without having to resort to using the EVF in bright light.

WIRELESS PERFORMANCE

IMG_5797.jpg
What we love most about the A7R III's connectivity is its user-friendliness. Unlike with Fuji, which is either slow to connect or often makes you reconnect to the camera's WiFi network before it syncs with the app, you only need to establish that connection once. After that, the PlayMemories Mobile app will readily and quickly find that connection as soon as you turn the built-in WiFi on the camera. It makes using the app much more convenient.

This app, which is pretty straightforward and easy to use, allows you to transfer JPEG images on-the-fly, location tagging, viewing images on TV, and transferring images to an FTP server. 

IMG_8951.PNG
Most importantly, it allows you to control the camera itself, which is certainly useful in preventing camera shakes and for using the new Pixel Shift Function when you don't have a dedicated remote trigger handy. Though if you do, you might want to stick with the remote trigger... unless you need a remote preview.

One issue we've found is that the app can intermittently lose the connection for no reason, and it can take a while fetch images if you want to save a copy of every photo you take on your phone. The good news is that, because the app eventually reconnects to the WiFi, you don't need to leave the app and reconnect on your settings. You just have to have a bit of patience.

One-touch or NFC for Android and Bluetooth connectivity are also on hand to give users several options.

BOTTOM LINE

DSC00121-2 2.jpg

Once you get your hands on the A7R III, you'll never want to look back. This is the mirrorless that has everyone salivating, including Nikon and Canon users, with its well-balanced combination of speed, performance, high resolution, and image/video quality in a lightweight but robust package that has great handling and is easy to familiarize.

It isn't perfect. As we have already pointed out, it has its share of flaws. But Sony has taken to great lengths to make this camera one of the best, and it certainly tries to make up for many of these flaws. Plus, it's got a few aces up its sleeves that are missing in other cameras of the same caliber. In fact, in some ways, it even surpasses the A9. (We said some!)

Is it worth the $3,198 price tag? It's not too steep of a price for what you're getting in exchange. If you're on a limited budget, you might find a cheaper alternative--the new A7 III, for example. But with the A7R III's top-of-the-line refinements, you honestly wouldn't care.

Pair it with a stunning glass, and you'll be in shutter heaven.
