24.2MP APS-C Exmor CMOS Sensor and BIONZ X Processor

The APS-C-format 24.2MP Exmor CMOS sensor realizes smooth, nuanced image quality with minimal noise and high sensitivity from ISO 100-32000, which can further be expanded to ISO 102400 for working in low-light conditions. The sensor features a unique design that utilizes thin copper wiring, enhanced circuit processing, and an enhanced front-end LSI to boost light-gathering abilities, reduce noise, and increase readout speeds to benefit video recording. The sensor and BIONZ X processor combination also avails a top continuous-shooting rate of 11 fps with AF and AE, or up to 8 fps with a silent shutter, and permits 14-bit raw file output for a wide tonal and color scale.

UHD 4K Video Recording in XAVC S Format

• Internal recording of UHD 4K video is possible in multiple frame rates up to 30 fps using the full width of the sensor with 8-bit 4:2:0 color sampling using the 100Mbps XAVC S codec.
• Oversampled 4K recording is also possible, which uses a 6K capture area within the Super 35 area, for greater detail. This full pixel readout is void of pixel binning for higher quality imagery with reduced moiré and aliasing.
• Affording extensive customizable color and gamma controls, the a6400 allows users to adjust the gamma, black level, knee, color level, and more. Use the same S-Log2 Gamma Curve that is found on high-end Sony Cinema cameras, which squeezes up to 1300% more dynamic range into the video signal than traditional Rec. 709, for increased post-production flexibility. HLG (Hybrid Log-Gamma) support is also available, along with the BT.2020 color space, for recording within a wide color gamut and, in addition to S-Log2, S-Log3 is also available for producing an effective 14-stop dynamic range with increased grading control in the shadow to mid-tone regions of the image.
• In addition to high-resolution internal recording, uncompressed HDMI output also enables the use of an optional external recorder for clean 4K recording with 4:2:2 sampling.

• Interval shooting mode is ideal for creating time-lapse movies with the aid of Imaging Edge software. Intervals can be selected between 1-60 seconds for recording up to 9999 sequential frames.
• 4K video recording also avails the ability to produce 8MP stills during playback by taking a frame grab from a movie and storing it as a separate file.
• Slow & Quick (S&Q) mode allows shooters to capture Full HD video at specified steps between 1-120 fps. These settings will allow you to slow down action as well as speed up a slow-moving scene.

4D FOCUS

Covering nearly the entire sensor area, a powerful 4D FOCUS system incorporates 425 on-chip phase-detection points along with 425 contrast-detection areas for precise focusing in as little as 0.02 seconds. The density of focusing points from this hybrid AF system also enables High-density Tracking AF Technology, which is adept at tracking moving subjects in a variety of lighting conditions.

• Real-time Eye AF can be used to base focus on recognized human subjects' eyes for portraits and is available in both AF-S and AF-C modes and for both stills and video.
• Eye AF can be used when photographing animal subjects, too, with any focusing mode when shooting stills.

• Lock-on AF maintains focus on moving subjects throughout the use of a configurable frame that is set over the desired moving subject
• Expand Flexible Spot employs neighboring focus points to retain focus on moving subjects even if the originally selected point loses focus
• The Focus Magnifier function can be used for critical focus when homing in on minute subject details
• Rear touchscreen can be used for Touch Focus and Touch Tracking control and a Touchpad Focus Control mode lets you use the rear screen intuitively while keeping your eye to the viewfinder
• In addition to autofocus, the a6400 also features a Peaking MF function to benefit manual focus control by highlighted sharp edges of contrast for a more objective means of acquiring sharp focus
