Sony A6400 Review: Updated with Pro Videographer Comments

Virtually precisely Three years after saying the A6300, the Sony Alpha 6400 has been unveiled as its alternative. This digital camera APS-C format mirrorless digital camera seems lots like the A6300, however it comes with an enormous enchancment within the autofocus efficiency. To be truthful, the A6300 wasn’t a slouch in that department, but Sony is absolutely main the pack in this area and the A6400 makes capturing shifting subjects straightforward. There’s also a flip-up display to attraction to selfie-shooters and vloggers, along with a powerful video specification. Discovering the display a bit wanting for setting the AF point once I look within the viewfinder, I might’ve appreciated a joystick on the again of the digital camera, however that’s probably too much to hope for on a digital camera at this worth.

The Sony A6400 doesn’t just have a flowery specification sheet, it additionally delivers where it matters, with high-quality photographs and movies.

  • zero.Three-inch OLED with 2,359,296 dots viewfinder
  • In-body intervalometer

Like the A6300, the Sony A6400 has a 24.2Mp APS-C format sensor, nevertheless, this can be a extra trendy chip. It’s also paired with an up to date model of the Bionz X processor. Consequently, Sony has pushed the sensitivity range further, hitting ISO 32,000 within the native vary and ISO 102,400 within the expanded range.

There are additionally new image processing algorithms on-board to help ship better picture high quality.

One thing to notice is that the Alpha 6400 doesn’t function in-body stabilisation (IBIS). If you need that you must look to the subsequent model up, the A6500, which can also be due for alternative. Nevertheless, Sony presents some stabilised lenses, including the PZ 16-50mm package lens.


Probably the most exciting developments is with the autofocusing. It attracts on the know-how in the Sony A9, A7R III and A7 III. There’s a complete of 850 AF points, 425 that use part detection and 425 that use distinction detection. These are stated to be packed together tightly and cover 84% of the image space.

That dense protection helps make the A6400 good at figuring out and tracking subjects.

Sony additionally claims that the new-generation BIONZ X image processing engine allows the digital camera to realize focus in just 0.02sec.

As well as, there’s ‘Real-time Eye AF’, the newest model of Sony’s wonderful Eye AF system. This mechanically locates the eyes in actual time to get them sharp. You possibly can even set a choice for specializing in the left or proper eye. There’s additionally Actual-time Monitoring that makes use of synthetic intelligence (AI) to help recognise subjects. Collectively, these should end in quick and correct focusing in a wide range of conditions to permit the photographer to focus on getting the composition right.

Excitingly, Sony may also add Animal Eye AF help with a firmware improve in Summer time 2019. That’s nice news for keen wildlife photographers and pet house owners.

Steady Capturing

Like the A6300, the A6400 can shoot at up to 11fps (frames per second). Nevertheless, there’s an enormous leap in the burst depth as the A6400 can shoot as much as 99 Additional Positive Jpegs, or 46 raw information. This compares nicely with the 44 Additional Positive Jpegs or 21 raw information attainable with the A6300. Nevertheless, both cameras can shoot up to 21 pictures when recording uncooked and Jpeg information concurrently.

If you want to shoot silently, the maximum price is 8fps. That’s quite a pace for a digital camera at this degree.

It’s also good to see an intervalometer built-in. This allows you to set a capturing interval of between 1 and 60 seconds for up to 9,999 photographs. The pictures can then be made right into a time-lapse film on a computer operating Sony’s Viewer software program.


Sony has given the A6400 a powerful collection of video options. As an example, it could shoot 4K (3840 x 2160 at as much as 100Mbps) video in tremendous 35mm format with full pixel readout and no pixel binning. This means there’s oversampling and round 2.4x as much knowledge is gathered than is needed for the final video. It’s a methos we’ve seen before it helps to supply larger high quality films.

There’s also a selection of XAVC S (MPEG-Four AVC/H.264) or AVCHD (MPEG-Four AVC/H.264) format. As well as, 4K HDR (HLG) recording is accessible for playback on suitable televisions and S-log3 and S-log2 gamma modes are offered to offer higher scope for post-capture grading.

The S-Log gamma curves enable you to seize as much as 1300% wider dynamic range than is generally attainable. The end result could be very uninteresting, flat wanting footage, but after grading to introduce some contrast, you’re left with movies that have each spotlight and shadows element.

The S-Log3 setting additionally provides up to 14Ev latitude.

Whereas there’s a Three.5mm port to connect an external mic, headphones can only be hooked up by way of the elective hotshoe adapter. Nevertheless, utilizing the adapter blocks the view of the display when it’s tipped up.

A Sluggish and Quick movement (S&Q) choice on the mode dial allows the A6400 to shoot sluggish movement video at as much as 5x slower than real life and fast movement at as much as 60x quicker. All the work is completed in-camera and pictures is saved in Full-HD.

Alternatively, Full-HD footage may be shot at as much as 120fps with a bit-rate of as much as 100Mbps to create slow-motion films post-capture.

Construct and Dealing with

Based on Sony, the A6400 is has a magnesium alloy design and is mud and moisture resistant. Meanwhile, the shutter is rated at 200,000 cycles.

Sony has stuck with the rectangular, rangefinder-like design of the A6300 for the A6400. Which means the viewfinder is over in the top-left corner. I find this design much less pure to use than a DSLR-style digital camera, however it means right-eyed photographers can see around the digital camera more simply with their left eye.

The falt design doesn’t prolong to the entrance of the digital camera and the Alpha 6300 has an honest grip.  With a light-weight optic just like the 16-50mm package lens mounted, you possibly can shoot one-handed pretty easily.

Aside from a joystick on the back of the digital camera to set the autofocus point, nearly all the key controls that you simply want are offered and inside straightforward attain. Within the absence of a joystick, the quickest strategy to set the AF point is to use the touch-screen. More on this later.

There’s additionally plenty of opportunity to customise the Sony Alpha A6400’s controls. For example, it can save you up to three sets of custom settings to make multiple settings modifications shortly. It’s additionally attainable to customize the aim of the rear and prime command dials when a customized button is pressed.

Sony A6400 review

As well as, there are seven customisable buttons and the 12 features within the Perform (Fn) menu might be set to your personal preferences. I discover the usual association fairly good, but after a while, I changed two of the settings so I might have faster access to the Silent shutter and Facet ratio controls.

There’s additionally a My Menu part that may be customised to let you attain the options you employ most frequently quicker.

Sony A6400 review


There’s excellent news with the Three-inch 921,600-dot display of the A6400. First up, it’s touch-sensitive. As traditional with Sony, you’ll be able to’t use the touch-control to navigate the menu and make setting alternatives. Nevertheless, Touch Pad, Touch Focus, Touch Shutter and (a new) Touch Tracking options are available. The latter prompts ‘Real-time Tracking’ while Touch Pad lets you set the AF point by way of the display while wanting within the viewfinder.

Further good news is that display might be tilted by way of 180-degrees vertically to allow it to be seen from the entrance. That’s nice for selfie-shooters and vloggers who want to be able to see themselves in front of the digital camera.

The dangerous news for stills photographers is that Sony has caught with the 16:9 facet ratio display for the A6400. That’s great for video, nevertheless it makes pictures shot within the native Three:2 ratio seem a bit small.

Sony A6400: price, release date, official specs confirmed

As a left-eye-shooter, I have to be careful about which area of the display I exploit to set the AF level once I’m wanting in the viewfinder. If I exploit the whole display, or decide the incorrect space, my nostril strikes the AF point. I began out utilizing the bottom-left nook of the A6400’s display but this proved tough to succeed in when a large, heavy lens like the Sony FE 70-200mm f/2.8 GM OSS was mounted. Consequently, I swapped to the bottom-right nook and used my right thumb on the display to pick the point.

Nevertheless, there have been quite a number of occasions when the display didn’t reply to my touch when the digital camera was held to my eye. The Sony A7R III and A7 III appear more responsive on this respect, but they both have joysticks on their rear.  This meant that I typically moved the digital camera away from my face or I pressed a custom button to access the AF space choices after which set the purpose utilizing the navigation controls.

Sony A6400 review


The Sony Alpha A6400 has the identical 0.39-inch sort 2.36 million-dot electronic viewfinder (EVF) because the A6300 and A6500. This has 0.7x magnification and for those who rummage via the menu, you’ll find an choice to spice up the body price from 60fps to 120fps. The latter provides a smoother view but eats up the battery energy a bit faster than the usual setting.

In both mode, the EVF offers a pleasant clear view with a superb degree of element. Nevertheless, it’s somewhat too brilliant within the default settings. Consequently, it’s a good suggestion to scale back its brightness by way of the menu. Within the default settings, there’s a danger that you simply’ll scale back the publicity unnecessarily.

Sony A6400 review


Sony hasn’t simply gained floor in the digital camera market due to the impressive specification of its cameras. They ship the image high quality that photographers want as properly. Searching by way of my pictures from the Sony Alpha A6400, I can spot a couple of which might be slightly underexposed as a result of the viewfinder appears a bit shiny, but the majority are good. Within the default settings, it produces fairly vibrant colors that may attraction to most people.

Something to note, if you wish to seize fast movement across the body, or for those who’re panning, it’s worthwhile to keep away from the Silent capturing mode in any other case your topic is more likely to endure from the rolling shutter effect.

Autofocus System Performance

Up to now, I might often opt for a single AF point and then do my greatest to keep it over the topic. Sony’s intelligent AF system makes this largely unnecessary and it means you possibly can think about features such because the composition and timing of the shot.

As traditional with a Sony digital camera, the A6400 has a set of autofocus (AF) area modes. Of these, Large provides the digital camera probably the most scope to pick the AF area point. It’s the equivalent of Auto Space AF on other manufacturers’ cameras. Beforehand, I might’ve shied away from such a setting but current developments mean it may be very helpful. It definitely proved to be so with the A6400. As well as with the ability to spot and monitor my ever-present dog, I found it worked very properly when photographing birds in flight. It spotted them within the frame and stored them sharp as they moved across the frame and either in the direction of or away from the digital camera.

As I’ve discovered with other Sony cameras, when its set the continual AF the system can wrestle to determine the topic if it’s not shifting, and can typically focus just in entrance of it. When it strikes, nevertheless, it latches on shortly.

Real-time Eye AF and Real-time Tracking

Sony’s Eye AF system has proved to be a serious bonus to wedding ceremony and social photographers. In the A6400 its more more likely to be directed at family and friends nevertheless it works extremely properly. I discover that it spots and focuses on a subject’s eyes when they are concerning the measurement that they are just visible in the viewfinder. By which I imply across the level when you possibly can distinguish the eyeballs from the eyebrows. And it does an amazing job of staying with them.

Similarly, the Real-time Tracking, which uses AI, makes preserving the subject sharp straightforward.

In line with Sony the low-light capability of the A6400’s AF system is best than the A6300’s and it will possibly perform at -2Ev in AF-S mode. Presumably, AF-C (steady AF) mode requires a bit extra mild. And it was only really in low mild that the A6400’s AF system dissatisfied. It struggles a bit greater than I’d like. If you’ll find a high-contrast edge it could possibly typically get the topic sharp, nevertheless it slows down and hunts a bit.

Picture Quality

At the low end of the sensitivity range, the Sony A6400 captures loads of detail. Pictures look good and crisp, and even at 100% on display the whole lot seems pretty natural. As is to be expected, noise creeps into the equation because the sensitivity degree increases. Within the gloomy circumstances that require a setting of ISO 16,000 or 32,000 (the native maximum), Jpeg pictures can look a bit smudged in some areas.

At these settings, the uncooked information take extra cautious processing to seek out the proper stability between noise visibility and removing. Good results are potential, however I might stay inside the native sensitivity vary (ISO 100-32000) as a rule.

I was lucky to see some shiny sunshine throughout my time with the Sony A6400 and regardless of the excessive contrast circumstances, the A6400 retained the highlights in most photographs with out blocking up the highlights. The top result’s pure pictures that mirror the capturing circumstances properly.


Like the stills, the A6400 delivers high-quality video with loads of element and good colour. Shifting topics look clean and the focusing system might be relied upon to maintain them sharp. As ordinary, the perfect outcomes are produced in the event you take management and obey the 180-degree shutter rule, however you can even get respectable outcomes with the digital camera in its automated settings.

Small crop marks point out the framing within the highest quality setting, but they can be arduous to see with busy scenes.

Pro Comment

We spoke to skilled videographer, educator and mentor, Brent Kirkman about how and why he uses the Sony A6400 for his work. Right here’s what he had to say.

Why the Sony A6400?

I primarily shoot wedding ceremony videos with the Sony A7 III and A6400. I’d tried utilizing the A7 III on a DJI Ronin-S stabilising gimbal and it was very heavy. Plus, each time I changed lens or zoomed to a special focal length, I had to readjust the gimbal or danger damaging the motors.

The Sony E PZ 18-105mm F4 G OSS lens provided a solution to the zooming drawback as a result of it doesn’t change size once you modify the focal length or focus. It’s also a power zoom, which is right for video.

Because the 18-105mm is an APS-C format lens, it made sense to go for an APS-C format digital camera. I went for the A6400 because its focusing is superb and I don’t want the in-body stabilisation of the A6500.

I’ve set the control wheel on the aspect of the Ronin-S to zoom the lens. Different individuals use it to regulate focus but I belief the digital camera’s AF system. I really like how the A6400 may be set to trace a topic with a faucet.

And of course, the bonus is that the A6400 is smaller and lighter than the A7 III. It makes a perfect gimbal digital camera with the E PZ 18-105mm F4 G OSS. That’s a very good focal size range, equal to 27-157.5mm

I can now run behind the bride and groom and shoot good and tight on their arms, for instance, after which zoom out while still shifting to reveal the whole scene round them. Usually you’d have to try this from a hard and fast point, with the ability to do it on the move actually provides impression.

Now the A6400 lives on the Ronin-S and I can actually drive to the wedding and be capturing right away.

What settings do you employ?

Until a shopper particularly requests or needs 4K video, I all the time shoot in 1080p. It saves on space for storing and processing time. But in addition, it’s far more forgiving on pores and skin.

My default setting is Log mode, which suggests the sensitivity is all the time ISO 800 or above. I’m joyful to go all the best way as much as the top of the ISO vary, but I don’t need to use the A6400 a lot in low mild as a result of that’s often once I’m capturing on the dance flooring and I need to hold my package to a minimal then. The Ronin-S would get in the best way, in order that’s once I mainly use the A7III handheld or on an extended monopod to shoot from above.

I often overexpose all the things by a cease or two. I can pull all the things back within the submit manufacturing nevertheless it helps get the look we would like.

We all the time set the white stability by eye, matching the video cameras with the stills cameras. They’re Sony A9s.

I set the AF Drive velocity (film) to Fast and the AF Monitor Sensitivity (movie) to Normal. Because of this if I decide a new point of focus the digital camera adjusts shortly but when the topic moves away from the purpose of focus it doesn’t modify the main target shortly. The top result is smoother more filmic video.

Usually, we would like the whole lot to be quite dreamlike, so I often shoot at f/4 on the A6400 for the shallowest depth of area I can get.

The video quality from the A6400 is great. I can mix footage from it with video from the A7III and not using a drawback.

It’s nice that Sony has put the work in on the autofocus system for the A6400. It’s something that may really assist photographers of all levels. Actual-time Monitoring apart, it’s not quite as fast or as dependable because the AF system in the Sony A9, nevertheless it’s excellent, particularly for a digital camera that is set to retail for less than £1000/$1000.

Further excellent news is that the Animal Eye AF shall be rolled out to the brand new digital camera in the summer. As well as being useful for budding wildlife photographers, it ought to be useful for family photographers who need to embrace their pet of their pictures.

I was hoping that Sony would undertake a mini-DSLR design for the subsequent spherical of its APS-C format cameras and give them a joystick for AF level selection. I discover this design more snug to hold and use. Having the viewfinder in the midst of the top plate would in all probability rule out having a flip-up selfie display,  however I was hoping for a vari-angle monitor anyway. A vari-angle monitor is extra helpful for photographers who need to shot portrait format photographs.

Those issues aside, the A6400 could be very an excellent digital camera for anyone starting to get critical about images. It’s attractively priced and it has a comprehensive range of features for each photographers and videographers. While the 16-50mm package lens is good and compact, I’m not an enormous fan of the facility zoom. Until you actually need to hold measurement and price down, I’d opt for the 18-135mm package. You lose a bit at the wide-angle end however it’s a extra versatile focal size range and you have a standard zoom mechanism.
