The Touch Focus function allows the desired focus point to be specified instantaneously by touching the subject on the monitor. Touch Shutter function instantaneously focuses on the subject touched on the monitor and releases the shutter, so that the desired subject can be captured with one touch. The touchpad function allows smooth focus position adjustment while using the viewfinder. Sliding a finger across the monitor moves the focus area position and can be moved smoothly while looking through the viewfinder. Touch Tracking function, works by touching the subject that you wish to focus on the screen and then half-pressing the shutter button activates Real-time Tracking. When shooting movies, touching the subject initiates tracking that maintains focus on the subject.

Interval recording for time-lapse videos
Time-lapse movies document changes with the passing of time. The a6400 features built-in interval recording, for time-lapse movie creation, that can be set anywhere between 1 and 60 seconds, with a total number up 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. The still images shot can then be edited into a time-lapse movie on a computer with the Viewer software from the Imaging Edge software suite. A convenient variable-speed preview function is also provided to get an image, on the camera, of how the finished movie will look. Combining with silent shooting means that you need not worry about durability of the mechanical shutter. When interval shooting is carried out over a long period, the camera can use an optional mobile battery or the multi-battery adaptor kit NPA-MQZ1K to supply power (not provided), so shooting outdoors and/or for extended periods is worry-free.

HDR video with LG (Hybrid Log-Gamma)
HLG (Hybrid Log-Gamma) picture profile that supports an instant HDR workflow. Recorded movies played back on an HDR (HLG) compatible TV, without the need for color grading, will appear true-to-life, with no blocked shadows or blown highlights. The BT.2020 color space is supported, providing a wider color gamut. Four gamma settings are provided (HLG, HLG1, HLG2, HLG3). The HLG setting conforms to ITU-R BT.2100, while The HLG1, HLG2, and HLG3 gamma settings provide wider dynamic range. The balance of dynamic range and noise produced by each setting is different, allowing selection to best match the scene being recorded.

S-Log shooting support
The S-Log3 and S-Log2 Gamma curves feature wide dynamic range (up to 1300%) to minimize whiteout and blackout, and permit wider movie expression by performing color grading in post-production. The S-Log3 gamma setting further realizes a 14-stop latitude. The S-Gamut, S-Gamut3, and S-Gamut3.Cine color spaces are handled. A wide variety of professional end-uses such as cinema and broadcast are supported.

Zebra function
Checking exposure is often difficult especially when shooting movies in the S-Log setting, but the Zebra function is provided to simplify the task. The Zebra display brightness level standard is IRE 0 – 109%, and the target range can be set freely between +10% and -10% of a selected value in 1% increments. This helps users to easily adjust exposure whether shooting still images, 4K video and when using S-Log2 and S-Log3, by specifying the target value and range of the exposure level for Zebra display in accordance with their intentions. Furthermore, users can set a minimum brightness level.

Gamma Display Assist8
Gamma Display Assist8 is a function that allows users to monitor images or check focus while enlarging images of natural contrast when recording in the S-Log setting. It converts S-Log and S-Log into ITU709 (800%) gamma for monitoring on the LCD screen or viewfinder.

Ultra-fast OLED w/ EVF benefits and optical viewfinder immediacy
The 2.36 million-dot XGA OLED Tru-Finder electronic viewfinder has the ability to deliver continuous live shooting at up to 8 fps with AF/AE tracking - making it easy to track fast moving subjects - thanks to overall improvements in the EVF algorithm.

16-bit processing and 14-bit RAW output
The a6400 employs 16-bit processing and 14-bit RAW output for natural gradations. The digital signal from the image sensor’s AD converter is processed in 16-bit form by the front-end LSI and BIONZ X processor before being output as 14-bit RAW data to the memory card. The result is smoother, more natural gradations that contribute to higher overall image quality. Compressed and uncompressed 14-bit RAW format are supported.

High-quality view mode for finer, natural detail
A menu setting allows viewfinder and monitor display quality to be set to “Standard” or “High.” The “High” mode takes maximum advantage of the data read from the 24.2 effective megapixel sensor to provide extra fine viewfinder and monitor displays, with finer detail and a more natural overall view that can be a huge advantage when focus is critical. The Standard setting provides longer battery life.

Monitor OFF selectable via DISP button
A new “Monitor OFF” selection has been added for the DISP button while shooting. When “Monitor OFF” is selected the monitor will be off except during image playback and when using the menus. This can be useful when shooting the night sky or in other situations where a bright monitor might be a distraction.

GPS location data via Bluetooth
The α6400 offers location data acquisition via a Bluetooth connection to a compatible mobile device with Imaging Edge Mobile App installed. After the camera has been paired to the Imaging Edge Mobile installed on a compatible mobile phone or tablet device, it can acquire location data from the mobile device and record that data with still images. The acquired location data can also be used to correct the camera’s date/time and location settings.

Silent Shooting
Silent Shooting features an electronic shutter that is noiseless so you can shoot high-resolution images in situations that require complete silence. Continuous autofocus and auto exposure is available when using silent shooting.

AF accuracy in dark scenes
Advanced AF algorithm contribute to high AF precision in AF-S mode down to light levels as low as EV-2 (ISO 100 equivalent, F2.0 lens), a step darker than the α6300. Shooting using highly precise AF is possible even in dark scenes.

More detailed face detection settings
The face detection feature has been updated with individual AF Face Detection Priority [ON/OFF], Face Detect Frame Display [ON/OFF] and Multi AE Face Detect Priority [ON/OFF] settings that were not available on the α6300. This provides the flexibility needed for a variety of situations, such as where face priority needs to be applied in AF only, for example.

AF in Focus Magnifier
When shooting stills, it is possible to use autofocus while the selected image area is magnified in the viewfinder or monitor. You can even magnify the view after autofocus has been achieved for finer focus confirmation or refocusing. Since this function can be used to focus on an area smaller than the Flexible Spot, it is ideal for macro photography and other situations where focus must be precise.

Additional 1:1 image aspect ratio
In addition to 3:2 and 16:9 aspect (width: height) ratios, the 1:1 aspect ratio used by Instagram etc. can also be selected. This eliminates the need for cumbersome hand-trimming of images after shooting before they can be posted on social media.

Proxy recording
4K movies and lower-resolution proxy movies can be recorded simultaneously. Proxy movie files are smaller than the corresponding 4K files, and are therefore ideal for quick previewing or pre-editing that can reduce the time required for final 4K editing.

Photo Capture (image extraction from movies)
Users can select, extract and save still images of decisive moments from movie footage (frame grabs). High-quality 8-megapixels stills can be extracted from 4K video and 2-megapixels from Full HD video in camera during playback and stored as separate files on the media card.

Peaking function makes manual focus even easier
The excellent performance of the advanced BIONZ X image processor has improved the detection accuracy of the peaking function that color-highlights the most sharply focused area during manual focus and direct manual focus shooting. It’s now easier than ever to identify the focus peak areas during the delicate focusing required in macro or portrait shooting. Blue has been added to the peaking colors (red, yellow, white). The expanded range of colors from which an easily-visible peaking color can be selected, depending on the subject and environment, improves the visibility when using the peaking display.

AF tracking sensitivity adjustment
When shooting movies, the sensitivity with which autofocus will follow subjects that move outside the focus area can be adjusted. Sensitivity should be set [High] for subjects at varying distances which require repeated refocusing, whereas the [Standard] setting can prevent the focus from jumping to new objects and maintain stable focus on a subject that is briefly obscured by other objects.

ISO value display while movie shooting
When shooting movies in ISO Auto mode, the current ISO value can be constantly displayed. If concerned about noise levels in a dark location, for example, the user can monitor the current ISO value.

Additional initial focus magnification setting
When shooting movies, it is now possible to set the initial focus magnification. In addition to the current 1x > 4x, a new 4x only setting has been added. Through the setting of frequently-used magnifications, the number of focus magnification operations can be minimized.

4K movie transfer to smartphone
By using the newly introduced smartphone app Imaging Edge Mobile, high-bitrate movies including 4K can be transferred to smartphones (Probability of transfer / playback depends on the performance of the smartphone). Refer to the product information for Imaging Edge Mobile for details

Microphone jack and XLR adaptor kit compatible
The a6400 provides a microphone jack for an external microphone and a MI (Multi-interface) shoe which provides direct connectivity to a range of compatible MI-shoe microphones. The MI-shoe also provides line input via optional XLR adaptor kits (XLR-K2M/XLR-K1M) that allow the connection of many types of pro (XLR) microphones. A modest audio set-up with some noise reduction supports better sound quality suitable for serious movie shooting or self-shooting for vlog.

High bitrate Full HD high-speed recording at 120 fps2
High-quality slow-motion sequences can be created during post-production processing as high-speed Full HD recording at 120 fps2 is supported. A max. 100 Mbps high bit rate recording is possible with XAVC S2 format.

Enhanced menu usability
An illustration to indicate position of camera control keys and buttons are added to the custom settings screen. A glance confirms which button or switch one is attempting to assign to. Another improvement in menu usability is that function menu options can be viewed when setting the function menu, improving ease of operation.

Restricted display of AF area and ISO display limit
On the AF area setting screen, a new function has been added that displays only focus area types that the user uses frequently. Another new function on the ISO setting screen displays only frequently-used ISO ranges. These allow setting changes to be made efficiently while shooting. These display restrictions apply even when “Switch Focus Area” is assigned to a custom button.

Improved AWB control
Auto white balance can now be locked or unlocked at any time with the “AWB Lock function”. This is convenient when one wants to fix auto white balance in an environment with multiple (artificial and natural) light sources. Setting the white balance color temperature has been simplified as well as reducing the steps in setting of custom white balance. With “Priority Set in AWB”, when white balance is set to Auto and incandescent lamps or similar are the light source, the color tone priority can be set to Standard, Ambience, or White. Ambience priority produces a warm tone, while white priority produces accurate white reproduction.

Power supply via USB "The α6400 can be powered via USB connection to AC adaptor, a PC or mobile battery. This conserves the camera’s battery, allowing you extended use of the camera without worrying that the battery will run out. When the camera is turned off, the battery can be charged via the same connection.
