Virtuoso expression. Sony’s full-frame mirrorless α7R IV reveals ever more overwhelming photographic vision, with expressive prowess once expected only in medium-format cameras, and overpowering high speed in a compact body. See how its enhanced rigidity and connectivity raise your productivity.
New 61.0-Megapixel* Exmor RTM sensor
The α7R IV features a 35mm full-frame back-illuminated CMOS image sensor with approximately 61.0 million effective pixels, delivering depth and dimension that were once only available in medium-format cameras. Back-illuminated structure and effective noise reduction techniques combine to deliver an extraordinary blend of low noise and high sensitivity for enormous imaging potential.
BIONZ XTM image processing maximizes sensor potential
Advanced Detail Reproduction Technology and Area-specific Noise Reduction, both features of Sony’s BIONZ X image processing engine, have been carefully tuned to maximize the performance of a sensor that offers approximately 1.5 times more resolution than the highly acclaimed α7R III, achieving extremely fine, realistic reproduction of textures and details. Wide dynamic range is another advantage, with approximately 15-stops* available at low sensitivities for smooth, natural gradations from the deepest shadows to the brightest highlights. Portrait skin tones and the colors of nature are rendered with breathtaking realism.

Shooting and focusing speed
Combining 567 on-sensor phase detect autofocus points with refined tracking algorithms, the Alpha 7R IV boasts extraordinarily sophisticated autofocus abilities, with real-time tracking and eye autofocus enabled for both still and movie recording. All of this is available for fullspeed 10fps image capture with AF.
Quality & reliability
The body of the Alpha 7R IV has recieved a huge raft of tweaks and improvements to ensure reliability and intuitive operation. Dust and weather sealing has been enhanced, with improved gasketing for all buttons and ports. A deeper grip and improved button feel make for a more enjoyable shooting experience and more comfortable operation, and the new 5.76 million dot OLED viewfinder provides a new level of accuracy and detail while shooting.
Up to ISO 32000 with undiminished quality
A standard ISO range that extends from ISO 100 up to ISO 32000 and is expandable to ISO 50 ~ ISO 102400 for still images makes it possible to achieve optimum image quality in just about any light. Noise is effectively minimized even at high sensitivities, maintaining excellent image quality even with this sensor’s high pixel count.
5.76 million-dot UXGA OLED Tru-Finder
The α7R IV features a new UXGA (Ultra-XGA) OLED Tru-Finder with 5.76 million dots, for outstanding detail, contrast, and brightness. A “High” quality mode provides extra fine viewfinder and monitor displays with minimal moiré and jaggies, for finer detail and a more natural overall view, and a 120/100fps* finder frame rate setting provides a smooth viewfinder image with minimum display motion blur when shooting moving subjects. The eyepiece window is fluorine coated to repel fingerprints and grime, and make it easier to clean.
Sony’s Eye AF has completely changed the way many portrait photographers work. Now even further advanced technology takes portrait photography to the next level while opening the door to unprecedented, extraordinary potential.
The α7R IV provides new support for creative moviemaking with improved overall AF performance and Real-time Eye AF. For 4K movies, 6K oversampling delivers an overwhelming sense of depth and detail, while an HLG picture profile facilitates HDR content creation.
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.
