The Sony a7R IV combines high-resolution, true-to-life colours, and speed in a full-frame mirrorless camera. Image quality and details that are typically found in medium-format models are delivered with ease and convenience in the a7R IV thanks to a robust feature set, broad connectivity, and professional-grade reliability.
Another Milestone
61.0 effective megapixels, true-to-life gradations, and blazing speed come together in a full-frame mirrorless camera body that is capable of capturing reality you can almost feel. Image quality and expression that were once only possible with medium-format cameras are now available in a compact, lightweight α series full-frame body with features, connectivity, and reliability designed to support professional workflows both in the studio and out on location. Stunning stills and movies with professional reliability and productivity. Another milestone from the leader in mirrorless imaging.
New 61.0-megapixel Exmor R 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 X 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.
Up to ISO 32,000 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.
Reliable low-vibration shutter
Shutter vibration that can cause blur is reduced to a minimum, even when shoot-ing continuous bursts at up to 10 frames per second, thanks to a new shutter unit with a fast-response coreless motor. The system also includes a brake that sub-dues mechanical front and rear curtain shutter vibration, and dampers that absorb mechanical shock. Low shutter vibration is critical to achieving full quality from the camera’s high-resolution image sensor. The shutter is also quiet, and has been tested for durability in excess of 500,000 shutter cycles.
Class-leading speed and high-resolution continuous shooting with accurate AF/AE
An advanced mechanical shutter unit and updated image processing algorithms allow continuous shooting at up to 10 fps with accurate AF/AE tracking, even with this camera’s high-resolution 61.0 effective megapixel sensor. With this type of speed, you won’t miss the most photogenic moments and expressions of moving subjects. It is also possible to shoot continuously at up to 8 fps* in live view mode, with minimal viewfinder/monitor display lag for easy, stable framing, even with dynamic subject motion.
Up to 68 images per continuous burst
Buffer memory has been increased by 1.5x, allowing up to 68 Extra Fine/Fine JPEG or compressed RAW images to be captured in one continuous burst. Approximately 3x more continuous images can be captured in the APS-C mode, so you can shoot continuously with confidence.
Enhanced productivity for the working pro
PC Remote (tethered) shooting, where data is directly transferred to a computer so it can be viewed on a large monitor by staff and clients, is essential for smooth, productive workflow at model and product shoots. The α7R IV offers high-speed wired and wireless tethering capability with a number of file transfer and sorting options for maximum flexibility.
Full pixel readout without binning in Super 35mm mode for high-resolution 4K movies
Full frame and Super 35mm formats can be selected for 4K movie record-ing. Full pixel readout in the Super 35mm mode (approx. APS-C 16:9), without the need for pixel binning, makes it possible to condense ap-proximately 2.4 times the amount of data required for 4K movies (QFHD: 3840 x 2160), resulting in high-resolution, high-detail 4K with minimal moiré and jaggies. Further-more, the advanced image process-ing system delivers more accurate skin tones as well as smoother high-light gradations. 4K recording em-ploys the XAVC S format at bit rates as high as 100 Mbps.
