50.1MP Exmor RS BSI CMOS Stacked Sensor
Newly developed 50.1MP Exmor RS full-frame sensor features a stacked back-illuminated design with integrated memory that maintains high image clarity, expandable sensitivity up to ISO 102400, and a 15-stop dynamic range while also enabling fast 30 fps shooting and and phase-detection AF. The sensor also enables recording lossless compressed raw files for flexible editing during post-production while maintaining a relatively lightweight file size. Additionally, the 50.1MP resolution not only benefits stills shooters as it also offers full-frame 8.6K oversampling for 8K video recording.
BIONZ XR Processor
A revised BIONZ XR engine greatly benefits image processing capabilities throughout the camera system, including up to 8x faster processing, greatly reduced rolling shutter, and more fluent interface and file management handling speeds.
Up to 30 fps Shooting and Updated Shutter
Efficient sensor design and processing enables high-speed shooting up to 30 fps at full 50.1MP resolution, with full AF and AE capabilities, when working with an electronic shutter. When working with the mechanical shutter, speeds are still kept high at 10 fps. Also, a large buffer memory permits recording up to 155 compressed raw frames, or 165 JPEGs, in one single burst at 30 fps.
Suiting fast-paced continuous shooting is a blackout-free viewfinder experience, which makes use of a 240 fps refresh rate for fluent eye-level viewing.
Updated electronic shutter offers silent, vibration-free performance and also supports anti-flicker shooting for working under fluorescent, LED, or other flicker-prone types of artificial light, even while shooting at 30 fps with 120 fps AF speeds.
8K 30p and 4K 120p Video Recording in 10-Bit
Making use of the high-resolution sensor and fast processing capabilities, UHD 8K 30p XAVC HS 10-bit 4:2:0 video recording is possible using the full width of the sensor, offering 8.6K oversampling for impressive sharpness and realism. For easy handling of this high-res recording mode, low bit-rate proxy files with HD resolution can be simultaneously recorded faster for playback. Also, 8K video at 400 Mb/s can be written to a V90-rated UHS-II SD card, or 200 Mb/s to a V60 card, and 8K can be output over HDMI in 8-bit 4:2:0 format.
Recording up to UHD 4K is possible with frame rates up to 120p; when recording up to 60p the a1 offers full pixel readout and at 120p it uses a 10% crop. Oversampled 4K recording is also possible, via a 5.8K capture area, with a Super 35 crop. Internal 10-bit 4:2:2 sampling is also possible in all recording modes and, if recording externally via the full-size HDMI A port, 16-bit raw output is also possible from a 4.3K capture for even greater tonal reproduction and 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 a 15+-stop dynamic range with increased grading control in the shadow to mid-tone regions of the image.
Fast Hybrid AF System
Covering 92% of the image area, a Fast Hybrid AF system incorporates 759 phase-detection points along with 425 contrast-detection areas for quick and precise focusing in a variety of lighting conditions with sensitivity down to -6 EV. This focusing system is available for use in all recording modes, to benefit both video and stills applications.
Fast sensor readout and improved processing also enables up to 120 AF and AE calculations to be performed per second for faster, more responsive tracking and accurate results.
Lock onto subjects quickly using Real-time Tracking for AI-based tracking on moving subjects or touch tracking for manual selection of the subject.
Real-time Eye AF, suitable for both humans and animals, also ensures critical sharpness when shooting portraits.
Dedicated Real-time Eye AF Bird Mode lets you select the bird to be tracked and the camera will automatically detect the bird's eye and track it, regardless if the bird is in flight or still. This mode even works once a sitting bird takes flight.
Helping to fine-tune how the focusing system performs, seven-step AF transition speed and five-step AF subject shift sensitivity controls let you refine how quickly focus shifts from point to point and how smoothly focusing shifts occur.
5-Axis SteadyShot INSIDE Image Stabilization
Enhanced 5.5-stop effective 5-axis SteadyShot INSIDE image stabilization system compensates for five different types of camera shake encountered during handheld shooting of stills and video and allows users to confidently use any lens, even adapted lenses, for critical shooting without encountering blur from camera shake.
For long focal lengths, the system will correct for pitch and yaw adjustments. Macro and high-magnification imagery, on the other hand, will benefit from the inclusion of horizontal and vertical shift compensation. All shooting styles will get usage out of the roll compensation. All 5 axes of stabilization will function at all times, even when used with third-party lenses and adapters or lenses with built-in optical stabilization.
Additionally, specifically for video, there is also an Active IS mode that adds even more precise stabilization methods for even smoother footage straight out of camera.
Pixel Shift Multi Shooting
This unique compositing mode allows you to achieve even greater resolution than the 50.1MP sensor affords. Working in conjunction with the sensor-shift image stabilization, this mode shifts the sensor while making 16 consecutive exposures in order to acquire approximately 199MP of information for greater color accuracy and detail than possible with a single exposure. These files can then be merged together during post-production by using the Sony Imaging software suite.
