Reaching the peak of resolution: 61.0MP full-frame CMOS sensor
Sony’s newly developed 35mm full-frame back-illuminated CMOS sensor with 61.0 megapixels12 enables the full-frame mirrorless α7R IV to attain expressive prowess once expected only in conventional medium-format cameras. Thanks to this mirrorless design, absence of mechanical mirror shock can maximise resolution without negative effect on image quality. The α7R IV realises the level of image quality that surpasses the expectation for conventional full-frame cameras especially in the low- to mid-sensitivity range. Sony’s proprietary technology achieves superb high resolution while assuring low noise and high sensitivity.
Enhanced image processing engine makes the most of CMOS sensor
To match the excellence of the new image sensor, high-speed BIONZ X image processing engine is also further enhanced to faithfully reproduce details and reduce noise significantly. Noise that tends to occur due to heightened pixel count is minimised for high image quality, especially in the standard ISO sensitivity range up to ISO 32000. 13 Wide 15-stop dynamic range at low ISO sensitivity (for stills) delivers smoother reproduction of gradations from shadow to highlight. Moreover, the α7R IV’s inherited colour reproduction in still pictures — acclaimed in the latest α series — captures skin colour in portraits and vivid colour of flowers for natural α7R IV depiction.
Features maximising superb 61.0MP resolution
The α7R IV’s extremely high image 61.0-megapixel resolution performance is maximised by other α7R IV advantages, one of which is 5-axis optical in-body image stabilisation with optimised algorithms to achieve up to a 5.5-stop shutter speed advantage. Another outstanding feature is the electronic shutter allowing silent, vibration-free shooting. Additionally, the α7R IV incorporates an internal damper structure to absorb the impact of shutter motion for a minimum of shutter vibration. Many features in the α7R IV serve for realising sharply resolved imaging.
5.76-million-dot UXGA OLED Tru-Finder
Newly featured in the α7R IV, this 5.76-million-dot electronic viewfinder provides high-precision, high-brightness, and high-contrast visibility, reproducing fine detail with 1.6 times higher resolution than α7R III. “High Display Quality” mode draws on the effective 61.0MP (approx.) image sensor to suppress moiré and jaggies for highly precise and natural images on viewfinder; 120/100fps of “High” finder frame rate mode shows smoother motion, so it’s simpler to trace moving subjects. Fluorine coating makes it easier to remove dirt or a fingerprint from the lens, for more comfortable viewing in inclement weather and better concentration on shooting
Wide, fast, and steadfast AF evolution
Thanks to increased coverage and density of AF points and enhanced algorithm for tracking moving subjects, overall AF performance has evolved to provide steadfast, accurate tracking of complex subject motion and speed changes. The α7R IV’s Fast Hybrid AF system combines high-speed, highly trackable phase-detection and high-precision contrast-detection autofocusing, even for shooting venues as dimly lit as EV-3. 567-point phase-detection AF and 425-point contrast-detection AF provide wider image area coverage20 of 99.7% height and 74.0% width. In addition, this remarkable AF system provides as rapid response as α7R III, despite mass data handling due to the extremely high-resolution CMOS sensor, even in dim shooting venues.
14-bit RAW output for natural gradations
The α7R IV supports compressed and uncompressed 14-bit RAW output for smoother, more natural gradations that contribute to higher overall image quality. Taking advantage of even higher 16-bit processing in the imaging engine, front-end LSI and the enhanced BIONZ X image processor make 14-bit RAW output available even when shooting in silent or continuous mode.
Up to 68 images in continuous shooting
Professional photographers need to achieve consistent shooting without interruption. With 1.5x greater buffer memory, system speed, and UHS-II support, the α7R IV can capture up to approx. 68 images in a continuous burst at 10fps. With APS-C shooting mode, approximately three times more photos can be shot than with full-frame shooting mode. Fn menu/menu display access, setting changes, and review playback can occur during data writing. A countdown of the number of still images remaining to be written to memory is on display during playback.
Exceptional high-speed 10fps burst shooting with AF/AE tracking
Despite high resolution of 61.0MP, an ingenious algorithm enables efficient processing for high-speed continuous shooting of up to 10fps with AF/AE tracking through a mechanical shutter. It is also possible to shoot continuously at up to 8fps in live-view mode, with minimal display time lag for capturing fast-moving subjects. After a full-frame image is cropped down to APS-C size or if APS-C shooting mode is chosen, you can still get 26.2MP high-resolution images. This is a great advantage for wild animal photographers who rely on cropping after capturing images of quickly moving animals/birds afar.
Dual media slots, both supporting UHS-II
The α7R IV provides two media slots for SD cards, both SLOT 1 and SLOT 2 now compatible with UHS-I and UHS-II for fast mass-volume data writing. Two cards in the slots can be used to simultaneously record or relay record data; separate RAW data from JPEG data, or stills from movies; and copy data from one card to the other. A slide lock structure prevents the memory card cover from being opened unintentionally.
Real-time Tracking keeps focusing on tracked subjects
With this technology, accurate focus is maintained automatically while the shutter button is half-pressed. You can select a subject as you intend, rely on the α7R IV, and concentrate on your composition since the camera takes care of subject tracking. A newly adopted Real-time Tracking algorithm uses colour, pattern (brightness), and subject distance (depth) data to process spatial information while AI technology detects subject’s face and eye in real time. Available for both stills and movies.
Increased Fast Hybrid AF speed and precision for smoother, more stable movie AF
Faster, more precise Fast Hybrid AF achieves smoother, more stable autofocus in movie recording. This greatly reduces the need for focus operation when the camera is used on a gimbal or in assistance-free movie shooting. New Touch Tracking function is also available in movie recording, allowing you to simply touch an aimed subject on the monitor to initiate tracking. Swift AF-S operation is activated when shutter button is pressed halfway (or AF-ON button is pressed), for simplifying movie-making in “must succeed” situations including weddings and documentaries.
Making true-to-life high-resolution 4K movies
For high-resolution 4K movies with great detail but minimal moiré and jaggies, Super 35mm mode36 condenses approximately 2.4 times the data required for 4K movies (QFHD: 3840 x 2160). Advanced α7R IV processing records 4K movies with enhanced reproduction of skin colour and smoother gradations. In addition to S-Log3 and S-Log2 gamma curves, the α7R IV offers HLG (Hybrid Log-Gamma) picture profile for instant HDR workflow, supporting a wide range of HDR movie production needs. The α7R IV incorporates XAVC S recording format for 4K and enables high-quality images at high bitrates of up to 100Mbps
Reliable durability and weather resistance in tough situations
The α7R IV brings you further enhanced body durability, with full use of lightweight, high-rigidity magnesium alloy for covers and internal frame, keeping the camera highly rigid and light. In response to pro opinions, enhanced sealing is applied to battery cover, terminal cover, and all joints in the chassis, and a double-sealed sliding mechanism replaces the hinge to the media compartment lid for better moisture resistance.33 Routes to dust and moisture entry have been re-examined, and a cushion around the lens mount is added to ensure reliable operation in challenging environments.
