After lavishing a lot consideration on full-frame mirrorless cameras for the previous two years, Sony has lastly discovered the time to look once more to the smaller APS-C format. The lately launched A6400 ($900, physique solely) receives many options trickling down from Sony’s full-frame line, regardless of being lower than half the price.
The A6400, as its title would counsel, falls in simply beneath 2016’s A6500. Despite being lower-end, it advantages from being newer and provides many options — like a 180-degree flip display screen and sooner autofocus — not discovered on the A6500. Attending Sony’s A6400 launch occasion for the brand new digicam, this left us with one major query: Is it an unbeatable cut price, or too good to be true?
Same look, new tech
At 4.75 x 2.75 x 2.4 inches and weighing just below a pound at 14.3 ounces with battery and reminiscence card loaded, the Sony A6400 seems to be and feels virtually an identical to the A6500. The one notable distinction is the brand new LCD display screen. While the A6500’s may rotate up and down, the A6400’s flips a full 180-degrees into “selfie” place. Aside from taking pictures selfies, that is additionally a useful function for vloggers. In a little bit of a design flaw, you need to take away the viewfinder eyecup in an effort to get the display screen to the total 180-degree place, however the offending little bit of slides simply on and off. We should think about these eyecups are going to finish up in the identical graveyard the place all misplaced lens caps go.
For higher or worse, the management scheme stays largely unchanged, together with the minuscule film document button that’s awkwardly wedged into the sting of the thumb relaxation. We’ve complained about this for years, however, like Sony’s menu methods, our squawks — and people of different reviewers — have fallen on deaf ears.
David Elrich/Digital TrendsBut what Sony lacks in design sensibility, it makes up for with uncooked technological energy. One of our favourite options of Sony cameras is Eye-AF, the place the digicam focuses in your topic’s eye even because the particular person strikes by the body. This provides an unbelievable benefit for portraiture, and the system is dependable sufficient that it virtually at all times offers constant and predictable outcomes.
The new A6400 has an improved model of this method referred to as “Real-Time Eye AF” that not solely tracks the attention, however the particular person as nicely, because of synthetic intelligence. Better but, it really works routinely when you’ve enabled the system by way of the beautiful menus (extra on this in a bit). It additionally helps you to select which eye to concentrate on, or you may set it to computerized.

The firm took this expertise a step additional with Real-Time Tracking, which makes use of related algorithms and A.I. to acknowledge topics and observe them (no eyes needed). This is cool stuff and our transient use of the A6400 confirmed its potential. (Note: an A9 firmware improve due in March offers that digicam Real-Time Eye AF and Tracking whereas the A7R III and A7 III April firmware upgrades bestow Real-Time Eye AF for these full-frame cameras. Later this 12 months Real-Time Eye AF for animals can be launched for all of those cameras, thrilling pet lovers worldwide.)
Besides the brand new Real-Time options, the A6400 acquired a number of different boosts in comparison with older Alpha sequence cameras — and one obtrusive omission. The hybrid autofocus system has been improved to 425 section detect factors mixed with 425 distinction detect factors, an enchancment over the the dearer A6500 ($1,200, physique solely) which had 425 factors, however may solely use distinction detection on 169 of them. The new system covers 84 % of the picture space, near the 93 % of the full-frame flagship A9.
The A6400’s autofocus is the quickest of any Sony but, with a acknowledged .02-second acquisition velocity, a world’s finest. (Sony appears to make hundredth-second enhancements in autofocus with every new digicam that comes out, and we’d be mendacity if we mentioned we may at all times discover the distinction; the A6400 definitely felt very quick, nevertheless). Battery life has additionally improved to 360 pictures versus 310 for the A6500, though that is nonetheless far beneath the 700-plus ranking of the brand new A7 III full-frame digicam.
The A6400 receives many options from Sony’s full-frame cameras, regardless of being lower than half the price.
One level Sony emphasised within the reveal was that the A6400 would attain new heights in ISO efficiency for an APS-C digicam. It makes use of an identical 24-megapixel sensor to the A6500, however native ISO vary has been elevated to 100-32,000, expandable to 102,400. That’s a full cease enchancment over the A6500’s expanded max ISO of 51,200, however its native excessive of 25,600 is only a third of a cease behind the A6400.
Maximum mechanical shutter velocity is 1/4000 second, 1/32,000 with the digital shutter. Burst modes are unchanged from the A6500, topping out at 11 frames per second. That mentioned, the A6500 has a a lot bigger reminiscence buffer that may maintain a pair hundred photographs earlier than slowing down; the A6400 can shoot simply 99 JPEGs or 46 RAWs (in keeping with the specs) earlier than hitting the bounds of its buffer. Still, that is greater than sufficient for the overwhelming majority of shutterbugs, notably these procuring within the $900 worth vary.
Videographers can be happy with the oversampled 4K recording. For reaching greater dynamic vary, the A6400 provides each S-Log and, a primary for a Sony APS-C digicam, Hybrid Log Gamma (HLG). You additionally get a microphone jack, however just like the A6500, there’s no headphone jack. These are robust video options for a sub-$1,000 mirrorless digicam, however there’s one factor it lacks: in-body picture stabilization. This is the place the A6400 actually can’t compete with the A6500, which makes use of glorious 5-axis inner stabilization. This could possibly be a deal breaker for vloggers who in any other case could have flocked to the A6400 for its low value and flip-up display screen.
User expertise
Alongside some 50 journalists and YouTubers at Sony’s San Diego headquarters, we bought to check out a manufacturing pattern of the A6400. Sony provided three lenses with the digicam: the 24mm f/1.8 ($1,099), the 18-135mm f/3.5-5.6 ($599), and the ultra-wide 10-18mm f/4 ($849). Of these, solely the 10-18mm had optical stabilization.
Real-Time Eye autofocus and and Real-Time Tracking are main developments.
One good factor about these organized digicam occasions is that we get an opportunity to check the digicam in quite a lot of settings in a brief period of time, each indoors and out. Sony had organized jugglers, basketball and volleyball gamers, musicians, and even Frisbee-catching pooches to mannequin for us. As we had been additionally testing the A9 with its new firmware replace, this left us feeling fairly rushed, however we nonetheless bought a great sense for the A6400’s capabilities.
First off, the Real-Time Eye AF and Tracking are main developments. Rather than fumbling for controls throughout motion, you may focus in your topic and let the digicam do the heavy lifting. Sony had set customized controls and menus so the Real-Time options would have interaction with a half-press of the shutter button. This was nice and it must be the default for the digicam out of the field. We didn’t see an proprietor’s guide however we hope directions for enabling the Real-Time applied sciences are straightforward to observe, as a result of it’s a function that even informal shooters will recognize.
Low-light taking pictures was certainly one of enhancements Sony touted for the A6400. We did a sequence of photographs (tasting cups of tequila) in a dim restaurant as much as ISO 102,400. Sure, the colour shifted and there was loads of noise, however it was spectacular to see an APS-C sensor carry out so nicely. It received’t substitute full-frame, however it’s fairly good. Videos shot in low gentle had been additionally comparatively noise free with stable colour and little rolling shutter.
On the draw back, issues didn’t maintain up so nicely when taking pictures open air within the rain. Even with Real-Time AF, the images got here out smooth. Other photographers seen the identical factor and, guessing this was the fault of the lower-end lenses we had been testing, many people determined to swap within the G Master glass we had been supplied with the A9. Lo and behold, picture high quality was far superior.
1080p, 60fps pattern footageThis doesn’t precisely come as a shock, however it’s a reminder that even entry-level cameras can profit enormously from high-end glass. It’s a little bit of a disgrace, as a result of most individuals within the $900 bracket are doubtless going to be working with the extra reasonably priced lens choices, and people merely received’t attain the efficiency potential of the A6400. If you may afford to, it’s best to skip the equipment lens and save up for one thing higher. Sure, it’ll value you, however this has an enormous payoff and makes the distinction between a digicam that’s merely acceptable and one that’s distinctive.
Bottom line
The Sony Alpha A6400 is a stable digicam, particularly contemplating its $900 beginning worth. We had been very impressed with the brand new Real-Time autofocus applied sciences and may’t wait to see the place Sony takes them sooner or later. We’ll have to attend till we have now time to conduct a full evaluation earlier than providing a last verdict, and the shortage of in-body picture stabilization is definitely a difficulty for some potential patrons, however for now, we are able to safely say the A6400 exhibits a variety of promise, and no various instantly involves thoughts that may finest it at this worth level.
