Sony announces 61 MP a7R IV camera
Sony has launched the a7R IV camera with a 61.0-megapixel full-frame Exmor R™ CMOS sensor combined with BIONZ X™ imaging engine to deliver unprecedented resolution, fine gradation and low noise to open an entirely new dimension of detail just as pro photographers expect.
The α7R IV captures the mood of each scene and the texture of aimed subjects.
The latest image processing engine
The latest BIONZ X image processing engine works in tandem with front-end LSI to maximize high-resolution sensor performance while achieving up to 15-stop3dynamic range at low ISO sensitivity.
Wide standard ISO 100-32000 range
Regardless of increased pixels, the a7R IV delivers the highest standard ISO 320004 and reduces noise in the low- and mid-sensitivity ranges, achieving high-quality imagery.
In-body 5-axis image stabilization
The in-body 5-axis image stabilizer algorithm is optimized to maximize high-resolution 61.0-megapixel image sensor performance. This fully supports your handheld shooting for reliability as effective as 5.5-stop higher shutter speed.
Shoot in absolute silence
Silent shooting not only provides a useful advantage in venues where quiet is required but avoids vibration that can cause camera-shake blur. Vibration-free shutter maximizes extremely high a7R IV resolution for crisp clear images.
Blur reducing structure
A re-examined and redesigned mechanism infixes the shutter unit to suppress subtle camera shake and an enhanced image stabilizer algorithm effectively reduces image blur. Overall, the camera’s high resolution is successfully maintained.
Shake-free remote shutter release
Remote camera operation using optional wireless remote controller (RMT-P1BT) allows you to shoot effective stills while avoiding camera shake caused by pressing the shutter release. This maximizes the image sensor’s high resolution.
5.76-million-dot UXGA OLED Tru-Finder
This 5.76-million-dot electronic viewfinder reproduces fine detail with approximately 1.6 times higher resolution than a7R III. You can select “High” quality mode for high-precision yet natural realism while suppressing moiré and jaggies for better concentration. Smoother image with a 120/100fps6frame rate makes it easy to track moving subjects.
Burst speed:
Regardless of remarkable image resolution, the a7R IV maintains its shooting speed of up to 10fps with a mechanical shutter (up to 8fps in live-view continuous shooting mode). This allows you to capture decisive moments—such as motion of wild animals—with subtle details made possible only by the 61.0 MP high-resolution imaging capability.
Useful 26.2 MP with APS-C cropping
Thanks to extraordinary image resolution, you can still maintain remarkable high-resolution images at approximately 26.2 megapixels even after cropping a full-frame image down to APS-C size. This means the a7R IV can help you proactively utilize 61.0-megapixel full-frame shooting, for example, in bird photography that tends to require cropping editing to magnify captured images.
Wide AF coverage
New image sensor supplies wide and high-density AF coverage with 567 phase-detection AF points (approx. 99.7% height and 74.0% width). 425-point contrast-detection AF supports precision focusing.
Fast AF despite higher resolution
Thanks to responsive enhanced Fast Hybrid AF, despite its large data handling, the a7R IV delivers swift AF even under dim lighting conditions, with remarkable ability to capture an aimed subject.
Steadfast AF tracking further improved
Increased AF points, widened coverage of AF sensor and improved AF algorithm have further enhanced subject-tracking performance for consistent shooting, even of complex or sudden movements.
High-precision AF in low-light conditions
Advanced AF algorithms contribute to AF precision at light levels as low as EV-3. The ‘Focus Priority in Aperture Drive’ option is for more accurate focusing in dim lighting and when the aperture is stopped down.
Shoot up to 68 images continuously
Because buffer memory size is 1.5 times larger10, the camera maintains a burst shooting speed of up to approx. 68 images. With APS-C shooting mode, you can shoot approximately three times more photos than with full-frame shooting mode.
Dual media slots, both supporting UHS-II
Both SLOT 1 and SLOT 2 are compatible with UHS-I and UHS-II for fast mass-volume data writing. The a7R IV can simultaneously or relay record, separate RAW/JPEG data and stills/movies and copy data between cards.
Extend shooting to professional length
The a7R IV uses a high-capacity NP-FZ100 battery. For longer hours of shooting, combine this with the optional VG-C4EM Vertical Grip holding up to two NP-FZ100 batteries, which allows you to shoot two times more shots than with a7R IV.
Rely on smart AI-based Real-time Tracking
AI-based Real-time Tracking is newly featured to greatly increase your success rate in challenging shots. Simply designate a subject and press the shutter button halfway and rely on the camera to steadfastly track the subject. With “Face/Eye Priority in AF” function, the a7R IV seamlessly changes tracking targets between face and eye when the subject is a person.
Real-time Eye AF with animal eye tracking for more success
Thanks to an improved algorithm, the a7R IV now supports animal eye in addition to human eye tracking, allowing fast, precise, automatic detection and tracking. This animal eye support will greatly increase your success in capturing images of animals in the wild or favorite pets at home when an obstacle comes into view or the camera’s horizontal/vertical orientation often changes.
For Movies
Full frame and Super 35mm* formats can be selected for 4K movie recording. Full pixel readout in the Super 35mm mode (approx. APS-C 16:9), without the need for pixel binning, makes it possible to condense approximately 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. Furthermore, the advanced image processing system delivers more accurate skin tones as well as smoother highlight gradations. 4K recording employs the XAVC S*** format at bit rates as high as 100 Mbps.
