Sony A6400 Overview

Stable, fast, versatile, and compact, the Sony a6400 is an APS-C-format mirrorless camera that adopts many of the features normally reserved for their full-frame lineup. This includes an autofocus acquisition of 0.02 seconds, Real-time Eye AF and Real-time Tracking capabilities, high-speed shooting up to 11 fps and silent shooting up to 8 fps, both with AF/AE tracking, an upgraded BIONZ X image processing engine, an LCD touchscreen that tilts 180° up and 74° down, UHD 4K movie recording with full pixel readout and no pixel binning, internal recording for time-lapse videos, and more.

The a6400 is well-suited for both photo and video creators, ranging from professionals to vloggers. Revolving around a 24.2MP Exmor CMOS sensor and BIONZ X image processor, clean image quality is provided with a wide expandable sensitivity range of ISO 100 to 102400, along with accelerated readout speeds for internal 4K24 and Full HD 1080p120 video recording with full pixel readout. The processor further benefits videographers with the inclusion of an S&Q (Slow & Quick) Motion setting that permits capturing Full HD video at a variety of frame rates ranging from 1-120 fps, plus HLG (Hybrid Log-Gamma), which supports HDR workflows, and both S-Log2 and S-Log3 for color grading flexibility. Stills shooters also benefit from the processing speed, which enables continuous shooting at 11 fps for up to 116 JPEGs, 46 raw images, or 44 raw and JPEG frames in a burst, as well as 14-bit raw file output. The sensor and processor combination also avail 4D FOCUS, with a wide-coverage 425-point phase-detection system that covers around 84% of the image area, and a 425-point contrast-detection system, both of which provide quick and precise focusing performance. This focusing system also enables Real-time Eye AF, which delivers improved accuracy, speed, and tracking performance of Eye AF, so the eyes of your subject are automatically detected. Furthermore, Real-time Tracking uses AI-based object recognition and processes color, subject distance (depth), and pattern (brightness) as spatial information to ensure that all subjects can be captured with accuracy. Increasingly versatile and fully featured in both photo and video realms, the a6400 is a fast and precise imaging tool for multimedia capture.

Complementing the imaging assets, the a6400 sports a robust magnesium-alloy body with sealed buttons and dials to help keep out dust and moisture, plus anti-dust functionality that protects the optical filter. The compact profile incorporates a high-resolution XGA Tru-Finder 2.36m-dot OLED electronic viewfinder for bright, clear, eye-level viewing, and this EVF features a 120 fps viewing mode for smooth tracking of fast-moving subjects. A rear 3.0" 921.6k-dot touchscreen TFT LCD monitor is also available and tilts 180° up and 74° down to benefit shooting from high and low working angles. The touchscreen design also allows for intuitive touch-to-focus control. Additionally, for wireless remote control over the camera, or for just sharing imagery online, built-in Wi-Fi with NFC permits linking with a mobile device for intuitive wireless control.

General Features

Capture Decisive Moments

The autofocus system on the a6400 inherits many technologies from Sony's line-up of full-frame cameras, including the a9, a7R III, and a7 III models. The a6400 features 425 phase-detection AF points and 425 contrast-detection AF points that are placed densely over the entire image area, covering approximately 84% of the image area. This high-speed, high-performance tracking AF system is paired with a BIONZ X image processing engine that together allow the camera to acquire focus in as little as 0.02 seconds and maintain subject lock effectively, ensuring even the fastest moving subjects can be tracked and captured with ease.

The a6400 introduces advanced "Real-time Eye AF," the latest version of Sony's Eye AF technology. This capability employs artificial intelligence-based object recognition to detect and process eye data in real time, resulting in improved accuracy, speed, and tracking performance of Eye AF. In all autofocus modes, the camera now automatically detects the eyes of the subject and activates Eye AF with a half press of the shutter button, and when in AF-C or AF-A mode, the preferred eye (left or right) of your subject can be selected as the focus point. Choices include Auto / Right Eye / Left Eye, and a Switch Right / Left Eye function is able to be assigned to a custom function as well. This technology frees the photographer to focus solely on composition with trust that focus will be tack sharp on the subject's eye. Eye AF support for animals will be added in summer 2019 via a system software update.

Also debuting on the a6400 is Sony's "Real-time Tracking." This mode utilizes Sony's algorithm that includes artificial intelligence (AI) based object recognition and processes color, subject distance (depth), and pattern (brightness) as spatial information to ensure that all subjects can be captured with accuracy. Additionally, when photographing or videographing humans or animals, face and eye position information is recognized by AI and the subject's eye is monitored in real time with high tracking precision. This can be activated by a simple half press of the shutter button or can be assigned to a custom function

In terms of overall shooting speeds, the camera can shoot at up to 11 fps with full AF/AE tracking while utilizing the mechanical shutter, and up to 8 fps with full AF/AE tracking while silent shooting. It can shoot at each of these speeds for up to 116 frames JPEG Standard / 46 frames raw compressed, greatly increasing the chances of capturing the moment.

Advancements in Image Quality

Sony's a6400 is equipped with a 24.2MP APS-C image sensor that is paired with an upgraded BIONZ X processor to deliver improved image quality and color reproduction in all types of shooting conditions. Standard ISO ranges up to ISO 32,000 for both stills and movies and is expandable up to ISO 102,400 for still images, with good noise reduction at medium and high sensitivities.

The camera also inherits many of the image processing algorithms from Sony's full-frame cameras, suppressing noise while preserving resolution and improving texture depiction.

4K Movie Recording with Fast Hybrid Autofocus

The versatile a6400 is a solid video camera, offering internal 4K UHD (3840 x 2160) movie recording with full pixel readout and no pixel binning to collect about 2.4x the amount of data required for 4K movies, and then oversamples it to produce high quality 4K footage with detail and depth. Focusing during movie shooting is fast and stable thanks to upgraded Fast Hybrid AF technology, which keeps the subject in constant smooth focus, even if an object crosses in front of the camera. This advanced AF plus touch focus functionality makes it a suitable camera choice for many vloggers and video creators that are regularly creating and uploading content online.

For time-lapse movie creation, the camera features built-in interval recording that can be set anywhere between 1 and 60 seconds, with a total number of shots from 1 to 9999. AE tracking sensitivity can be adjusted to "High", "Mid," or "Low" during interval shooting, allowing for reduced changes in exposure over the shooting interval.

Additionally, for the first time in a Sony APS-C mirrorless camera, this model includes an HLG (Hybrid Log-Gamma) picture profile, which supports an Instant HDR workflow, allowing HDR (HLG) compatible TV's to playback beautiful, true-to-life 4K HDR imagery. Further, both S-Log2 and S-Log3 are available for increased color grading flexibility, as well as Zebra functionality, Gamma Display assist, and proxy recording. The camera can also record Full HD at 120 fps at up to 100 Mb/s, allowing footage to be reviewed and eventually edited into 4x or 5x slow-motion video files in Full HD resolution with AF tracking.

Upgraded Build for Increased Versatility

This camera is designed to offer a high level of functionality and customization to maximize shooting freedom. The a6400 features a fully tiltable 180° 3.0" LCD flip screen with 921,600 dots of resolution that allows for simple and effective framing of selfie-style shooting for both still and video capture. Utilizing this capability, vloggers will be able to check and monitor composition throughout their entire creative process. The LCD screen is also equipped with touch functionality, with options for Touch Pad, Touch Focus, Touch Shutter, and Touch Tracking, which quickly activates "Real-time Tracking" through the touch screen.

The camera features a high-quality XGA OLED Tru-finder viewfinder, extensive customization with 89 functions that are assignable to 8 custom keys, My Dial and My Menu functionality, enhanced overall menu usability, a help screen for menus, star rating for images, and many other features that allow for a seamless shooting experience. It is also built with a tough magnesium-alloy design and has a durable shutter that is rated for approximately 200,000 cycles. It also is capable of seamlessly transferring files to a smartphone or tablet when connected to the new Imaging Edge Mobile application.

E PZ 16-50mm f/3.5-5.6 OSS Lens

The included E PZ 16-50mm f/3.5-5.6 OSS lens provides a 24-75mm equivalent focal length range, covering wide-angle to portrait-length perspectives to suit working in a wide variety of situations. It features Optical SteadyShot image stabilization to help minimize the appearance of camera shake by up to four shutter speed steps to greatly benefit working in low-light conditions and with greater zoom magnifications. One extra-low dispersion element and four aspherical elements are integrated into the optical construction to help reduce chromatic aberrations as well as increase clarity, sharpness, and contrast and the Power Zoom electronically-driven zoom mechanism brings greater efficiency to controlling the zoom position of the lens.

I got this body as I was looking for a crop MILC with E-mount (as another member of my family already has E-mount lenses I can borrow). That doesn't leave a lot of options, but I thought the a6400 would still be a good option. I was wrong. Let's start with the good. Sony is still one of the best options when it comes to dynamic range. And, being a MILC, you have a nice and short flange to focal distance--only 18mm for E-mount bodies. However, that's where the pros end and the cons begin. The two most frustrating of these are the star eater, which affects astrophotographers like myself, and the lack of lossless raw, which affects anyone who would like the option. The former is well documented, and although things are not as bad as they were when it was first introduced, it's still an issue to this day. For this reason, I'm still using my old Canon DSLRs for astro, despite the fact that their decade or older sensors are not nearly as good as modern ones. I knew about this before buying as was willing to forgo astrophotography on this body, as frustrating as that is. The other issue, the lack of lossless raw, is much more annoying and likely affects a lot more people. The lossy compression of Sony's raw files cannot be turned off in the a6400, unlike in their FF bodies that I've also shot (the a7R II and a7R IV). For some reason, Sony appears to reserve this 'feature' only for their FF bodies, which is annoying to those of us that prefer to shoot on crops. Other annoyances from much earlier Sony bodies have continued for generations, and are still present in the a6400. For example, the ergonomics are terribly, as the camera is really too small to grip comfortably, and the grip itself is poorly shaped. My Canon 450D and 600D, both larger bodies, are much more comfortable to operate and hold. Another issue with the small body is that it necessitates a small battery, exacerbated by the fact that MILC use up power faster than their DSLR ancestors. Carrying two batteries with me at all time is a requirement, not an option, as it was with the Canon DSLRs. Software wise, Sony's menus are still atrocious, and they have been for some time. Numerous reviews of earlier bodies have made similar remarks, and yet years later this is still a problem? With a company of Sony's size, this should have been fixed in the second generation of bodies, or even before the first was released. Plan to spend several hours customizing the cameras settings before you can use it easily when you actually go out to shoot. Although I plan to mostly use the body for stills, I definitely wanted the option of shooting UHD video with it as well. While the a6400 does feature some nice things when shooting video (e.g. BT.2020 and HLG), it has some major flaws as well. The first of these is the awful rolling shutter. This is painfully apparent on any sort of rapid motion, where things turn to jello when moving horizontally across the screen. The UHD video modes offer both 24p and 30p, the latter of which is a crop (which does reduce the rolling shutter). While that's likely out of necessity, it begs the question: why is there no 24p crop mode? This would let you shoot 24p with less rolling shutter, but isn't offered. The second issue with video is you are stuck with 8-bit limited range (only 220 levels of gray). Wide gamut, HDR video sorely needs 10-bit to avoid banding issues, ideally with the option to record in full range (1024 levels of gray). This simply isn't available on the a6400. For this reason, as well as the rolling shutter, I suggest you look elsewhere if you're serious about shooting video. I considered returning the body, but as I really want something that's both E-mount and crop, there simply aren't any other options in that space that are better. It's not a feeling you want when you buy a new body.

I use it for live streaming church services as a part of a multicam setup, we use a bmd atem mini pro for switching and it works flawlessly just with the kit lens and a dummy battery (granted we have a lot of natural light in the room). AF is always on point no matter what, works great for this application.
