The Alpha a6400 from Sony 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.

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. 

Increasingly versatile and fully featured in both photo and video realms, the a6400 is a fast and precise imaging tool for multimedia capture. 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 from shooting from high and low working angles. The touchscreen design also allows for intuitive touch-to-focus control. 

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 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. 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 are recognized by AI and the subject's eye is monitored in real-time with high tracking precision. 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. 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.

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. 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.

The E PZ 16-50mm f/3.5-5.6 OSS Lens from Sony offers a versatile equivalent zoom range of 24-75mm as well as a retractable design that makes your system much more manageable when not in use. Helping to deliver excellent optical quality throughout the range is an extra-low dispersion element and four aspherical elements to combat various aberrations and improve contrast. The lens also incorporates Optical SteadyShot image stabilization and a power zoom mechanism, both of which will help you capture smooth and steady stills and video. A variable aperture of f/3.5-5.6 helps keep the lens' overall size and weight to a minimum. Four aspherical elements are incorporated in the lens design to reduce astigmatism, field curvature, coma, and other monochromatic aberrations. Enjoy smooth zooms ideal for shooting movies with the power zoom mechanism available in this lens.
