Sensor and Processor
33MP Exmor R BSI CMOS Sensor
Newly developed 33MP Exmor R BSI CMOS full-frame sensor features a back-illuminated design that promotes high claritylow noiseand vivid color rendering. This design benefits working in low-light conditions and works in conjunction with a broad sensitivity range of ISO 100-51200. The sensor's design also achieves an impressive dynamic range of approximately 15 stops and files can be recorded in rawJPEGor the 10-bit HEIF format.
BIONZ XR Processor
Using the flagship-class BIONZ XR enginehigh-speed image processing capabilities are available for fast continuous shooting4K video recordingand advanced AF tracking performance. The quick processing also helps to reduce rolling shutter and other motion distortions for clean rendering of moving subjects.
In terms of shooting speedsthe sensor and processor enable up to 10 fps shootingusing either the mechanical or electronic shutter and with AF/AE enabled. Alsothe buffer permits recording up to 828 consecutive uncompressed raw + JPEG frames when using a CFexpress Type A card.
Video Recording
4K 60p Video Recording in 10-Bit
- Making full use of the high-resolution 33MP sensor and fast processing capabilitiesUHD 4K 24p/60p XAVC HS 10-bit recording is possible using the full width of the sensoroffering 7K oversampling for impressive sharpness and realism.
- There is also oversampled 4K recordingvia a 4.6K capture areawith a Super 35 cropthat offers UHD 4K output up to 60p in 10-bit.
- No recording time limit allows for unlimited clip lengths and the camera's physical design features an improved heat-dissipating structure to promote longer possible recording times; longer than one hour of continuous 4K 60p 10-bit 4:2:2 recordingfor example.
- The a7 IV employs a pair of codecs to suit different workflows: XAVC HSwhich uses HEVC/H.265 encoding to retain more detail at smaller bitrates and XAVC S-Iwhich is an intraframe codec for consistent performance and quality at bitrates up to 600 Mb/s.
S-CinetoneS-Log3and Other Color and Gamma Controls
- S-Cinetone can be used to deliver distinct colors and healthy-looking skin tone rendering that matches the FX9 and FX6 camerasalong with the a1 and a7S IIIand is based on technology from the professional Cinema Line camerassuch as the VENICE. This color profile offers natural mid-tonessoft colorsand especially well-controlled highlights.
- HLG (Hybrid Log-Gamma) support permits recording within a wide color gamut for producing HDR-ready content directly from the camera.
- 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
AI-Based Autofocus
Covering approximately 94% of the image areaa Fast Hybrid AF system incorporates 759 phase-detection points for quick and precise focusing in a variety of lighting conditions with sensitivity down to -4 EV. This focusing system is available for use in all recording modesto benefit both video and stills applications.
Real-time Tracking and Real-time Eye AF
Borrowing from the flagship AF systemthe a7 IV has tuned tracking and subject detection capabilities that lock onto subjects quickly and refines focus accurately on recognized eyes and faces of subjects:
- Real-time Tracking is an AI-based subject recognition system that recognizes colorpatternand subject distance information for high accuracy and focusing speed.
- Beyond just tracking subjectsReal-time Eye AF fine-tunes the focusing accuracy and recognizes humananimaland bird's eyes for critical sharpness. Real-time Eye AF even maintains focus on a subject's eye when they leave and re-enter the frameallowing for working in more spontaneous shooting situations.
AF During Video Recording and Additional Focusing Modes
- Real-time Eye AF is fully supported during video recordingfor subject detection and tracking of humananimaland bird eyes while shooting.
- For more control over how focus shifts appear during recordingseven-step AF transition speeds 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.
- Focus Map is a unique way of visualizing depth of field and functions in a similar way to peaking with a colorful overlay of the scene that indicates which parts of the scene are in front of and behind the focus point depending on the chosen aperture.
- A feature carried over from the FX6 digital cine cameraAF Assist lets you intuitively switch over to manual focus control for adjusting focus position when working with AF. This is a quick way to shift selective focus between various subjects in a scene while recording.
- A unique solution to compensate for how certain lenses perform when racking focusFocus Breathing compensation will automatically smooth focus transitions and maintain a consistent field of view when changing the focus position during a shot. This mode crops into the image slightly and corrects for any detected shifts in composition when focusing is happening. This function is compatible with select E-mount lensescheck

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 lenseven adapted lensesfor critical shooting without encountering blur from camera shake.
- For long focal lengthsthe system will correct for pitch and yaw adjustments. Macro and high-magnification imageryon the other handwill 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 timeseven when used with third-party lenses and adapters or lenses with built-in optical stabilization.
