What’s the Sony A7R III?
The Sony Alpha 7R III is Sony’s newest high-resolution, full-frame mirrorless digital camera. It provides spectacular all-round specs, with a 42.4MP sensor, 10fps steady taking pictures, a hybrid AF system that employs 399 phase-detection factors overlaying roughly 68% of the body, and 4K video recording. It prices £3200 body-only.
It’s now 4 years since Sony unveiled the world’s first full-frame mirrorless cameras, within the form of the 24MP A7 and 36MP A7R. A year-and-a-half later, we noticed the up to date A7R II, with a groundbreaking 42.4MP sensor, built-in 5-axis picture stabilisation, and a much-improved physique design. Now it’s time for spherical three, within the type of the Alpha 7R III.
Sony has clearly determined to stay to what it is aware of finest and stored to a really acquainted template, with a compact, SLR-styled physique and central digital viewfinder. Nevertheless it’s taken the A7R II design and added lots of the finest options it debuted on the Alpha 9 earlier this 12 months, with the intention of addressing these aforementioned weaknesses. The result’s a really spectacular digital camera with a outstanding mixture of decision, taking pictures pace and high-ISO picture high quality.
In fact we’ve seen one thing very comparable just lately, with the Nikon D850 incomes excessive reward as one of the best DSLR we’ve reviewed thus far. The 2 cameras are priced in the identical ball-park (£3200 for the A7R III, £3500 for the D850) so that they’re sure to be intently in contrast; they’ll certainly additionally depart Canon customers pondering the worth of the similarly-priced however comparatively under-spec’d EOS 5D Mark IV. The query, although, is can the mirrorless A7R III genuinely compete with such an distinctive DSLR?

Sony A7R III – Options
Sony has employed basically the identical glorious 42.4MP back-illuminated full-frame sensor because the A7R II, with on-chip section detection for autofocus. Nonetheless it’s now been teamed up with the newest Bionx X processor and front-end LSI, bringing a barely prolonged customary sensitivity vary of ISO 100-32,000, expandable to ISO 50-102,400. The digital camera is claimed to supply totally 15 stops of dynamic vary at ISO 100, which might be recorded into its 14-bit RAW information even throughout steady or silent taking pictures (the place the A7R II fell again to 12-bit uncooked).
Talking of which, the A7R III is considerably sooner than the earlier mannequin, able to taking pictures at 10 frames per second (somewhat than 5), or eight fps with stay view between frames. It additionally has a significantly bigger buffer, which suggests it may possibly shoot 28 uncompressed RAW information in a single burst, or alternatively 76 compressed RAW or JPEG information. This counts as a uncommon mixture of decision and pace, surpassed solely by Sony’s personal Alpha 99 II electronic-viewfinder DSLR. A brand new shutter unit guarantees low vibration, and is rated for 500,000 cycles; a silent fully-electronic shutter can also be readily available for these events while you need to shoot as discreetly as potential.
Autofocus makes use of a hybrid system overlaying many of the picture space, with 399 phase-detection and 425 contrast-detection factors, a substantial enhance on the 25 CDAF factors within the A7R II. Sony says that it’s included the autofocus algorithms it developed for the Alpha 9, promising a ‘quantum leap’ in AF efficiency, with 2x sooner focusing alongside massive enhancements in focus monitoring and Eye-AF efficiency.
Like its predecessor, the A7R III consists of 5-axis in-body picture stabilisation that works with virtually any lens. However due to improved algorithms, it now guarantees blur-free hand-held taking pictures at shutter speeds 5.5 stops slower than would in any other case be potential. In accordance with Sony, that is the simplest picture stabilisation system but employed by a full-frame digital camera.
In a really welcome addition, the A7R III makes use of the identical uprated NP-FZ100 battery because the Alpha 9, providing over twice the capability of the previous NP-FW50. It’s specified for 650 photographs utilizing the LCD, or 530 with the EVF, in accordance with CIPA customary testing. The A7R III additionally positive factors twin SD card slots, considered one of which is of the sooner UHS-II sort, and might routinely change between them when one fills up.
Sony has additionally added a few options which are fully new to the A7R III. Alongside the standard Micro-USB port, there’s a high-speed USB-C, which permits tethered operation by way of Sony’s new free Imaging Edge software program. Alternatively, you possibly can cost the digital camera via one USB port whereas utilizing a cable launch with the opposite.
In a much-requested addition, it’s now potential to guard pictures in-camera throughout playback, or assign them star rankings which are recognised by Adobe Lightroom and Bridge. One other neat contact is that bursts of pictures might be grouped collectively in playback, making it faster to flick thru your day’s taking pictures. I’ve discovered these options to be significantly helpful.
Wi-Fi is in-built for connection to a smartphone or pill, utilizing Sony’s free PlayMemories Cell app for Android and iOS. This permits full distant management of the digital camera, full with a stay view show. Sony additionally makes it significantly straightforward to switch pictures from the digital camera to your machine, just by urgent the Fn button on the digital camera’s again throughout playback. You may as well geotag your footage as you shoot utilizing your telephone’s GPS, by way of the newly-added Bluetooth connection.
Nonetheless just a few options are lacking in comparison with what I’d anticipate at this worth. As an example there’s no in-camera uncooked conversion, which just about each different model now provides. Neither is there a built-in intervalometer, and with Sony having apparently deserted its downloadable PlayMemories digital camera apps, no choice so as to add one. So if you wish to shoot time-lapse, you’ll need to make use of an old style distant launch or a third-party answer such because the Cascable three Wi-Fi app. That is disappointing for a £3300 digital camera.

Sony A7R III – Construct and dealing with
At 126.9 x 95.7 x 73.7mm and 657g, the A7R III is actually the identical measurement as its predecessor, however it has a barely deeper grip to accommodate the bigger battery. In consequence it feels subtly higher in your hand, providing a really constructive maintain even with bigger lenses such because the FE 24-70mm f/2.eight GM. There’s little or no to complain about when it comes to construct high quality, which feels each bit as stable as Canon and Nikon’s full-frame DSLRs. The primary query mark when it comes to construct hangs over the considerably slight plastic covers for the connector ports, and whether or not they are going to present pretty much as good sealing in actually troublesome situations because the thick rubberised covers on the likes of the D850.
Whereas the A7R III makes use of basically the identical top-plate management structure because the earlier mannequin, on the again it resembles the A9. So in a vastly welcome transfer it positive factors an AF-on button and AF-area choice joystick, together with a a lot better-positioned film button and a bigger, easier-to-use rear dial than the older mannequin. All the controls might be simply adjusted with the digital camera to your eye, with the joystick being particularly nicely positioned.
Certainly with the choice to make use of separate dials for every of the primary publicity parameters (shutter pace, aperture, ISO and publicity compensation), the A7R III does an amazing job of inserting an important settings at your fingertips. It additionally has loads of user-configurable customized buttons, which might be assigned to completely different capabilities throughout stills and video taking pictures or playback. It’s even potential to program as much as seven completely different digital camera set-ups for recall from the mode dial, and three particular subsets of taking pictures parameters that may be briefly engaged by urgent down a customized button (as an illustration, to vary focus and drive modes for when a topic begins transferring). This makes the digital camera extremely customisable, nonetheless it’s additionally fairly bewildering while you’re first attending to understand it.
Sadly, although, the A7R III doesn’t inherit the A9’s top-plate drive and focus mode dials; as a substitute these capabilities are accessed from exterior buttons. Presumably Sony assumes customers will change these settings much less typically than on the action-focused A9. It’s not an enormous drawback, however it means the A7R III is a bit much less fluid to make use of than it could possibly be.
Capturing with gloves on chilly winter days reveals one other flaw – the handgrip is positioned too near the lens mount. In consequence, with something aside from skinny gloves, you’ll wrestle to squeeze your fingers into the hole. In such conditions I needed Sony had used a barely bigger physique design extra just like the Olympus OM-D E-M1 Mark II or the Panasonic Lumix DC-GH5. Photographers preferring utilizing back-button focus may discover the AF-ON button to be awkwardly-placed too near the viewfinder, particularly in the event that they shoot left-eyed.
Sony’s relative inexperience additionally tells within the structure of the digital camera’s connector ports. Oddly the headphone and microphone sockets aren’t behind the identical cowl; as a substitute if you wish to use them whereas recording video, you’ll find yourself exposing the PC sync and HDMI ports too. Likewise, the corner-mounted micro-USB distant launch port is awkwardly situated to be used with the L-brackets beloved by panorama photographers. Once more, although, these are irritations somewhat than deal-breakers.
Sony A7R III – Viewfinder and display screen
Just like the A9, the A7R III employs a big, high-resolution three.69-million-dot EVF, which offers a shiny, detailed view that’s as massive as any full-frame DSLR’s. Relying in your preferences, it may be set to both 60fps or 120fps show modes, with the latter promising extra fluid movement on the expense of elevated viewing artefacts similar to moiré or jaggies. You may selected to overlay a variety of further info, however in considered one of Sony’s on-going failings, it’s not potential to see a stay histogram and digital ranges concurrently. Even so, the EVF is so good that I used it for the mast majority of the pictures I shot.
On the again the LCD has been upgraded to 1.44-million dots, with Whitemagic expertise for improved brightness. It’s additionally touch-sensitive for setting the main target level and inspecting magnified pictures in playback. Sadly although, Sony has insisted on sticking with its comparatively rigid tilt-only design. This has the benefit of being very compact and never interfering with connector ports, however it turns into ineffective the second you turn the digital camera to portrait format. I’d have most popular to see a dual-axis tilt or fully-articulated design, as on different top-end mirrorless cameras.

Sony A7R III – Autofocus
Like different mirrorless fashions the A7R III makes use of the primary picture sensor for autofocus, using a mix of section and distinction detection. This has an a variety of benefits in comparison with DSLRs; the main target space covers a a lot wider space of the body, and there’s no must program in micro-adjustments for every of your lenses to fine-tune accuracy. In consequence it’s a lot simpler to get persistently sharp pictures.
As common from Sony you get an array of focus space modes to select from. In Huge mode the digital camera will attempt to establish the topic wherever it could be within the body, whereas Zone restricts it to smaller areas. In Versatile Spot mode you possibly can place the main target level manually virtually wherever within the body; with Broaden Versatile Spot, surrounding focus factors are used to help the digital camera in focusing. For taking pictures portraits, Sony has included its spectacular Eye AF mode, which detects and focuses particularly in your topic’s nearer eye. This works remarkably nicely, buying appropriate focus with ease even while you’re taking pictures off-centre topics with quick lenses, the place DSLRs are inclined to wrestle.
Nonetheless most customers will, I believe, spend a whole lot of time in Versatile spot mode, setting the main target level utilizing both the touchscreen or the joystick. With the previous the digital camera behaves completely sensibly, highlighting the AF space in orange so you possibly can see the place it’s. But when like me you like to make use of the joystick, the main target space is drawn in a boring mid-grey that makes it basically invisible, which defeats the purpose of including that management within the first place. It’s remarkably incompetent of Sony to not have fastened this from the Alpha 9, and a critical failing for those who want to place your AF level manually. This will likely sound like a minor niggle, however I discovered it impacted on nearly all of photographs I took. It’s a critical flaw and in actual want of a firmware repair (which ought to be trivial for Sony to ship).
It is a disgrace, because the autofocus is absolutely superb certainly. It’s genuinely quick, which implies that in contrast to with the A7R II, you don’t end up continuously feeling simply that little bit held up by the digital camera. As common accuracy is spot on, simply so long as you pay shut consideration to the place you place the main target space. The AF additionally continues to work very nicely in low mild. The digital camera’s spectacular efficiency isn’t simply restricted to static topics, both – it’s additionally able to maintaining with people who transfer. It’s maybe not as unerringly dependable and correct because the Alpha 9, however it’ll often hold your topics acceptably sharp over the course of a burst, and works particularly nicely in live performance with Eye AF.
Sony A7R III – Video and 4K HDR
Like its predecessor, the A7R III is able to recording 4K video, utilizing both the complete width of the sensor or a Tremendous-35 crop. Within the latter mode it oversamples somewhat than pixel-bins, giving sharper, extra detailed footage. These hoping for top frame-rates in 4K should wait – the utmost continues to be 30fps – however what the A7R III does deliver to the desk is 4K HDR utilizing Hybrid Log Gamma, permitting excessive dynamic-range playback on suitable TVs, without having for any further processing. The digital camera also can concurrently output low-resolution proxy footage, which simplifies enhancing for videographers who use low-powered cellular units on the transfer.
Naturally Full HD recording can also be obtainable at body charges as much as 120fps, whereas microphone and headphone sockets are built-in for better-quality sound recording. There’s an enormous array of different video-specific options obtainable too, together with zebra sample over-exposure warnings, a customisable peaking show for guide focus, and S-Log gamma for simpler color grading in post-processing. Sony has additionally included its S&Q (Sluggish and Fast) mode, permitting Full HD recording at charges from 1fps to 100fps – in impact from one-quarter-speed sluggish movement, as much as 8x-speed fast movement.
It’s not simply the video specs which are spectacular: the Alpha 7R III delivers glorious high quality footage that’s filled with element. The in-body picture stabilisation additionally does a wonderful job of smoothing out the shakes from hand-held taking pictures. If you wish to shoot video in addition to stills, it’s an extremely succesful digital camera.
Sony A7R III – Pixel Shift Multi Capturing
Sony has launched a new ‘Pixel Shift Multi Capturing’ mode that makes use of the IS system to take 4 frames of the identical scene whereas shifting the sensor exactly one pixel between every, somewhat like we’ve beforehand seen on Pentax DSLRs. It writes 4 customary ARW uncooked information to card, which may then be mixed to a brand new ARQ format utilizing Sony’s Imaging Edge software program on a laptop computer or desktop laptop. This produces a composite file with full-colour sampling at every pixel location, which might be output in both JPEG or TIFF format.
Within the digital camera’s default setup, the mode can solely be engaged from the menu, however I added it as a shortcut to the Fn menu instead of focus mode (which has its personal exterior button). One drawback is that the digital camera has to attend a second or extra between frames, which causes issues in scenes the place any a part of the topic is transferring.
This type of multi-shot mode is just about a recognized amount now, and Sony’s model brings no massive surprises. So that you get considerably higher-quality pictures in comparison with typical single-shot mode, with vastly improved tonality and high-quality element when viewing your pictures on the pixel degree. You may see this within the instance above, though it should be stated the Sony Imaging Edge hasn’t executed an amazing job on the only uncooked file, and you would tease extra element out utilizing different software program similar to Seize One.
Nonetheless, this high quality is maintained provided that nothing strikes between exposures; if it does, you find yourself with an unholy mess. Within the crops above, you possibly can see some nasty grid-like artefacts on the out-of-focus waves, together with ugly rendition of the stones on the seashore. With most landscapes, you’ll see this type of factor throughout your pictures, and rapidly realise simply how uncommon it’s for something to remain completely nonetheless. It may be remedied in some circumstances by combining the single-shot and multi-shot pictures in Photoshop and masking away the worst artefacts, however with advanced landscapes it’s probably not an choice (or on the very least, an enormous quantity of labor!).
This all implies that, identical to different producer’s comparable modes, Pixel-Shift Multi-shot is nice for product images or nonetheless life, however has no likelihood of working for portraits or virtually any panorama. In these conditions the place Pixel Shift mode does work, nonetheless, the A7R III provides among the most finely-detailed pictures I’ve seen from any digital camera.
Sony A7R III – Efficiency
On the subject of in-the-field use, the A7R III is obvious enchancment on its predecessor, which might typically really feel a bit sluggish. Certainly it’s now a really snappy performer that merely will get on with the job with minimal fuss. Most notably, its significantly upgraded autofocus and steady taking pictures skills make it a reputable choice for high-speed motion work. Capturing wildlife in full decision uncooked at 10 fps, I discovered I used to be in a position to rattle off repeated bursts virtually at will, a minimum of till I ran out of area on my UHS-II card.
Battery life is much-improved over the A7R II too, with the NP-FZ100 offering enough juice for a reasonably intensive day’s taking pictures. That is nonetheless a mirrorless digital camera, in fact, so it’s a must to be taught to deal with it otherwise to a DSLR, flicking the ability change off while you’re not utilizing it. Nevertheless it doesn’t want wherever close to the identical diploma of babying and obsessive energy conservation as earlier than, and I believe most photographers will discover the A7R III’s stamina to be completely passable.
Picture high quality is, as we’d anticipate, distinctive. Whereas Sony’s 42.4MP sensor is just a few years previous now, it’s nonetheless top-of-the-line in the marketplace, matched solely by the 45.7MP unit within the Nikon D850. It offers an distinctive mix of excessive decision at low sensitivities with very low noise when the ISO is raised. Dynamic vary is really astonishing, particularly at ISO 100, with the power to tug an immense quantity of element from deep shadows with out extreme noise. This enables you expose to retain spotlight element in extraordinarily high-contrast scenes, then course of the uncooked file to deliver up the shadows.
On the entire the digital camera’s automated techniques do an excellent job. The metering is mostly very dependable in its multi-pattern mode, and it’s straightforward to visualise within the viewfinder when the digital camera will overexpose and dial within the requisite corrections. Alternatively the highlight-metering mode might be useful in high-contrast conditions the place you need to make sure of retaining element within the brightest areas of the body. I’ve additionally discovered the auto white steadiness to be much less susceptible to introducing odd color casts in comparison with earlier Sony fashions, with the A7R III typically offering extra enticing color output consequently. Certainly in my couple of weeks taking pictures with the digital camera, it’s barely put a foot incorrect.
Particular point out ought to be fabricated from the in-body picture stabilisation, which is extraordinarily efficient, significantly when utilized in live performance with Sony’s optically-stabilised lenses. Nevertheless it additionally permits you to shoot hand-held at sluggish shutter speeds with unstabilised lenses similar to quick primes, and fairly merely permits you to get sharp photographs over a a lot wider vary of situations. Within the instance above I uncovered for the realm across the mild, and was in a position to shoot hand-held at 1/2sec, and subsequently use ISO 100. The JPEG file was virtually fully black, however I used to be in a position to deliver up a lot of element out of the shadows by processing the uncooked file in Seize One. General I believe the in-body IS is the A7R III’s single largest benefit over DSLRs just like the Nikon D850, and purpose sufficient to decide on it as a substitute.
Sony A7R III – Picture high quality
Sony has used the identical 42.4MP BSI CMOS sensor as we beforehand noticed within the Alpha 7R II, and simply as in that digital camera, it provides completely excellent outcomes. Not solely does it present gorgeous ranges of element at low sensitivities, it additionally offers completely usable pictures at a lot greater settings than you may anticipate, with ISO 12,800 and even ISO 25,600 being completely possible. The uncooked information are extremely malleable too, and it’s potential to extract a whole lot of additional element from deep shadows in post-processing with out additionally citing extreme noise.
Sony A7R III – Decision
With its 42.4MP sensor and now low-pass filter the A7R III provides actually spectacular outcomes, resolving a minimum of 4800 l/ph earlier than the traces of our check chart begin to blur collectively. Some false element is rendered at greater frequencies, which can provide the impression of even greater decision in real-world taking pictures, though on the danger of maze-like aliasing and false-colour moiré. The digital camera’s spectacular noise efficiency additionally implies that decision doesn’t drop appreciably even at ISO1600. At greater ISO settings noise has an growing influence, however even at ISO12,800 the sensor delivers a minimum of three,200 l/ph. Naturally the highest settings aren’t so nice, however a studying of three,200 l/ph at ISO 102,800 continues to be fairly spectacular.
Right here our chart was shot from twice the conventional distance because of the A7R III’s sheer decision, so within the crops beneath multiply the quantity beneath the traces by 400 to get the decision in traces/image top.
Sony A7R III – ISO and Noise
At low ISOs the Alpha 7R III provides really gorgeous outcomes, with large quantities of element and no seen noise. What’s extra, there’s mot that a lot change at ISO 1600, with simply the best low-contrast textures beginning to blur away, and it’s solely at ISO 6400 that the picture actually begins to visibly degrade. By ISO 25,600 most pixel-level element has blurred away and shadows begin to block up, however colors are nonetheless sturdy. At prolonged ISO settings element and color endure significantly, however even at ISO 51,200 the remarkably clear shadows imply that pictures are nonetheless usable at a pinch.
Why purchase the Sony A7R III?
With the Alpha 7R III, Sony has executed a high-quality job of creating the A7R II design. It’s retained the identical completely gorgeous picture high quality, however added considerably sooner autofocus and steady taking pictures. Throw within the bigger battery and improved management structure, and it seems like a digital camera that may deal with virtually something that’s requested of it.
Certainly it’s troublesome to not conclude that the Alpha 7R III is one of the best mirrorless digital camera but made. It could not have the out-and-out pace of the Sony A9 or the elegant dealing with of the Fujifilm X-T2, however it’s nonetheless very fast, and works very nicely too – definitely a lot better than its finicky predecessor. Alongside the Nikon D850, it’s top-of-the-line all-rounders you should buy.
In comparison with the D850, although, the A7R III has all the same old benefits of mirrorless, together with a very correct viewfinder preview, a extra dependable and correct autofocus system and a significantly smaller physique, together with a lot better 4K video functionality. However to me, its trump card is its in-body stabilisation, which is extremely efficient and works with each lens. Mix this with the on-sensor AF and vibration-free mirrorless design, and it’s merely a lot simpler to get persistently sharp photographs that make full use of the sensor’s outstanding decision and dynamic vary.
Maybe the A7R III’s predominant drawback lies in its dealing with; it’s very a lot better than its predecessors, however nonetheless has just a few quirks and weaknesses. In distinction, Nikon has refined its high-end DSLR design over many generations to near-perfection on the D850. Some photographers may discover the A7R III too small for comfy use, whereas Sony’s fondness for making large lenses partially negates the digital camera’s measurement benefit.
In fact there are lot of DSLR customers with appreciable funding in lenses who’re unlikely to modify techniques proper now. However there isn’t a doubt the long run is mirrorless, and the Alpha 7R III emphasises simply how far forward of the competitors Sony is true now, a minimum of when it comes to the core expertise. It’s an exceptionally succesful digital camera that cements Sony’s domination of the high-end mirrorless market.

Fairly merely, the Sony A7R III is a ludicrously sensible digital camera, and one of many perfect in the marketplace.
