After letting rival digicam corporations catch up for the previous few years, Sony laid down a gauntlet with the 24.6-megapixel A9 III. It’s the world’s first mirrorless digicam with a global shutter, a much-awaited holy grail characteristic. It fully eliminates rolling shutter distortion discovered on CMOS cameras by studying your complete sensor without delay. It additionally boosts pace and removes the necessity for a mechanical shutter.
As a pioneering product, it’s not low cost at $6,000, however you’ll be able to anticipate the expertise to return down in value sooner or later. And there’s a draw back: Picture high quality is lowered in comparison with common cameras, because of the nature of a worldwide shutter.
Is it value buying and selling off picture high quality for further pace and lack of distortion, particularly in comparison with stacked sensor cameras which might be already fairly fast? To search out out, me and my professional photographer mates put a ultimate manufacturing mannequin via quite a lot of capturing situations.
Sony
Sony’s A9 III is the primary mainstream digicam with a worldwide shutter, marking yet one more leap in innovation by the corporate. The brand new expertise brings some massive advantages, particularly pace and the shortage of picture distortion as your complete sensor is learn without delay. It additionally affords massive advantages for content material creators, with 4K at 120 fps, 10-bit Log and no distortion for whip pans, and different fast paced content material. The principle downside is picture high quality that’s lowered in comparison with common CMOS cameras.
- Extremely fast
- Quick and correct autofocus
- Good stabilization
- Wonderful video capaibilities
- Diminished picture high quality
- Value
Physique and dealing with
The A9 III is Sony’s finest handling-camera but, borrowing all the most recent options of latest fashions just like the A7R V. It’s very mild for a full-frame digicam at simply 617 grams. And the redesigned grip is extra comfy and safe, which is a giant assist to working execs, particularly with heavy lenses. By comparability, Sony’s A1 might be laborious on one’s palms over a full day, in accordance with my photographer buddies.
There are three high management dials, making it straightforward to search out major settings in totally handbook mode. It has a pair of twin dials, with one for video, pictures and S&Q plus capturing modes, and the opposite controlling burst together with autofocus. You additionally get a rear joystick, management dial and a minimum of 5 customized buttons.
With all the pieces well-placed, it’s a cinch to shoot manually. Once you do have to delve into the menus, these are additionally effectively laid out. Settings are divided logically into classes, whereas the house menu reveals key choices (shutter pace, white steadiness, and so forth.) at a look. Every thing might be personalized, and you’ll again up your settings to a reminiscence card.
The high-resolution two million dot rear show is after all contact delicate for focus and menu management. It flips out and tilts up or right down to please each photographers and creators. The viewfinder is the very best on any digicam, with 9.44 million dots at 120Hz, or half that at 240Hz. That degree of sharpness makes it straightforward to test focus and colours. Once more, that is Sony flexing its tech muscle tissue as the first digicam EVF provider.

Battery life is a stable 500 photographs, however you’ll be able to double that with a brand new $400 vertical grip, which additionally provides you a greater maintain of the digicam. It has a dual-card slot setup with each SD UHS II and CFexpress. As typical with Sony, the latter is the slower Sort A spread, although. These are lower than half the pace of CFexpress kind A, however their smaller dimension permits Sony to do the twin slot setup.
Different key options embrace headphone and mic ports, with the choice so as to add Sony model microphones or audio equipment to the hotshoe. There’s additionally a full-sized HDMI port, USB-C charging port, ethernet, live-streaming functionality and extra.
Efficiency
With the worldwide shutter, twin Bionz processors and the identical devoted AI processor discovered on the A7R V,, Sony’s A9 III is the quickest full-frame digicam on the earth. Compressed RAW bursts might be shot at an unimaginable 120 fps with autofocus and auto-exposure, or you’ll be able to dial that right down to 60 fps or 30 fps.
A giant caveat is that the 120 fps mode solely works with supported Sony lenses, whereas third-party lenses are all restricted to fifteen fps. Hopefully the corporate will tackle that in a future firmware replace.
The buffer holds 200 RAW frames, so it fills up in lower than two seconds at most pace. It takes longer to clear the buffer than it ought to because of the CFexpress Sort A playing cards. When you use SD UHS II playing cards as an alternative, it takes about twice as lengthy to clear.
In any case, capturing at 120 fps is main overkill more often than not except you want wading via hundreds of pictures afterward. Sony does have an answer, although. You may shoot at, say, a still-very-fast 30 fps, then press the C5 button to allow the highest pace at key moments. That manner, you’ll get the shot you need with out losing frames.
The A9 III can also be the primary Sony digicam to make use of a pre-capture mode that saves a second of pictures while you half-press the shutter button. After you totally press it, these pictures are saved together with any taken after.
Your pictures will normally be sharp, too. The 759 phase-detect focus factors enable for terribly fast and correct autofocus in most conditions. For normal steady AF, it could sustain with even the quickest motion.
The AI-powered topic detection shines too. Face monitoring works with topics farther away and it follows somebody tenaciously, even once they duck behind obstacles. Human monitoring is quick and fluid, and you’ll simply see if it’s locked onto eyes, face or physique.
It might detect birds, animals (or each), together with bugs, vehicles and trains. It’s also possible to choose any distinctive object and the system will normally monitor it reliably.
The underside line is that it not often misses focus, so it’s nice for skilled sports activities, wildlife, weddings and extra. After all it’s not infallible and may combine up topics, however is healthier than any digicam I’ve tried up to now.
The A9 III has no want for a mechanical shutter as a result of there’s no rolling shutter distortion, which means you’ll be able to shoot in full silence always. With that, it’s good for sports activities like golf, as you’ll be able to shoot a participant in mid-swing with out disturbing them, and a membership in movement received’t be distorted.
It additionally permits for terribly quick shutter speeds as much as 1/80,000th and it could sync with supported flashes all the best way as much as that pace. It additionally eliminates the glint and banding from venue lights, one other massive assist for sports activities photographers.
Sony has additionally improved its in-body stabilization considerably, boosting it to eight stops with supported lenses. That enables photographs right down to 1 / 4 second or much less, matching Canon’s EOS R3 and besting the Nikon Z9 and Sony’s personal A1.
Picture high quality
1 / 31
As talked about, the first subject with this digicam is picture high quality. So is how a lot does it fall under common CMOS cameras? To check that, I shot in conditions together with gymnasiums, evening scenes, hen capturing, an airport and extra.
There’s no query that dynamic vary is lowered in comparison with Sony cameras just like the A1, no less than by a cease. The reason being that the sensor has much less mild capability because of the house taken up by the additional electronics.
It additionally has a smaller ISO vary, each on the excessive and low finish. Minimal ISO will not be nice at 250 and on the excessive finish, ISO is restricted to 25,600, half that of the A9 II.
Usually, there’s extra noise and fewer dynamic vary at any given ISO setting than the A9 II. On the identical time, the decision is decrease than rivals just like the Nikon Z9 and Sony’s personal A7R V and A1. So for landscapes, portraits and different varieties of images the place dynamic vary and backbone is vital (and pace isn’t), the A9 III isn’t the only option.
That stated, you’d have to pixel peep to note any main distinction in picture high quality between rival 24-megapixel cameras as much as about ISO 6400. For the meant viewers of sports activities, motion and wildlife shooters, it’s greater than ample.
Past that, photographs are noisier, however nonetheless usable as much as the utmost ISO 25,600 with noise discount (Sony seems to have extra aggressive noise discount for JPEG photographs at greater ISOs). I had no issue extracting good photographs in darkish scenes at ISO 6400 and even ISO 12,800. And as talked about, you could have extra management with a flash than some other digicam in the marketplace – in order that’s a stable choice in low mild.
In any other case, photographs are typical for Sony, with correct colours and pores and skin tones. The 14-bit RAW recordsdata are straightforward to work with and permit some pushing and pulling, significantly in highlights.
Video
Sony took benefit of the worldwide shutter to make the A9 III its most succesful mirrorless digicam for video. 4K at as much as 60 fps is supersampled utilizing the total 6K sensor width, whereas 4K at 120 fps will also be shot utilizing the total sensor, albeit with pixel binning. That mode helps full 120 fps playback as effectively, or slower playback modes through the sluggish and fast (S&Q) setting.
RAW 4K seize at 60 fps can also be potential utilizing an exterior recorder. All of these modes can be found with 10-bit S-Log 3 recording to increase dynamic vary in difficult lighting situations.
That’s simply the beginning of the A9 III’s video powers. Autofocus is as quick and correct in video as stills mode and has all the identical AI options. Meaning you’ll be sure you preserve even fast-moving topics sharp, whether or not they’re individuals, birds, animals or automobiles.
Those that choose to shoot manually can make use of Sony’s useful focus map characteristic. It has the auto-framing seen on earlier Sony fashions just like the ZV-E1 that lets YouTubers transfer round whereas filming themselves. You additionally get the digital zoom characteristic that reduces focus respiration for supported lenses, with some lack of high quality.
Airplane propeller distortion in video is a telltale signal of a rolling shutter digicam, so naturally we needed to take a look at the A9 III at an airport in opposition to Sony’s stacked sensor A1. Our findings? Whereas the A1 nonetheless produces flexible propellers, they’re after all useless straight on the A9 III. That trivial take a look at has massive implications. You may shoot issues like whip pans or a fast paced practice that you just’d by no means strive with a rolling shutter sensor. And since all the pieces is uncovered without delay like a movie digicam, it’s extra cinematic.
The A9 III does have some video competitors, as RED simply launched a pair of full-frame world shutter cinema cameras final month.
It has the identical wonderful video stabilization capabilities because the ZV-E1. Common optical stabilization is sweet for handheld photographs with out a lot motion, or you’ll be able to kick within the dynamic energetic mode for strolling. That gives close to gimbal ranges of smoothness, although there’s a substantial zoom and lack of sharpness.
A lot as with pictures, video high quality isn’t fairly as much as different full-frame cameras, with extra noise typically. I shot in S-Log3 more often than not to maximise dynamic vary and was glad with the outcomes. In low mild, I used to be compelled to make use of some noise discount.
High quality continues to be higher than any APS-C mirrorless or cinema digicam. I believe the worldwide shutter benefits, significantly the elimination of rolling shutter, might be well worth the tradeoff in high quality for a lot of videographers.
Wrap-up
Sony launched its first full-frame mirrorless digicam, the A7, years earlier than rivals, and was first to market with bottom illuminated and stacked sensors. These days although, rivals (particularly Canon) have been catching up and the sphere has leveled. With the primary world shutter digicam, Sony has taken a leap forward as soon as once more.
Picture high quality has held world sensor cameras again, however Sony clearly felt that the time was lastly proper. It was a sensible calculation — the A9 III is much better than I anticipated for a first-gen product. It affords mind-blowing speeds and unimaginable video capabilities, with a comparatively small price in picture high quality..
Its major rivals are the $4,800 Canon R3, Sony’s personal $6,500 A1, the $5,650 Nikon Z9 and $3,800 Z8, all stacked sensor cameras. The latter three provide a lot greater decision and higher image high quality, plus capturing speeds which might be nonetheless darn quick. All of them have some rolling shutter, although, together with flicker and flash sync points that don’t exist on the A9 III.
Whether or not it’s value risking that type of cash on new and unproven stacked sensor tech relies on the customer. Motion photographers and videographers received’t blink on the price in the event that they benefits of worldwide shutter will assist them make cash. Until you really want these advantages, although, Nikon’s Z9 and Z8, together with Sony’s A1, are extra versatile cameras — and the Z8 is considerably cheaper.
