Sony Alpha a7R IV Mirrorless Digital Camera (Body Only) Description
Sony Alpha a7R IV Mirrorless Digital Camera (Body Only) continues the noteworthy series of highly capable full-frame cameras, characterized by impressive stills and video performance and versatility. This fourth edition of the a7R sees the inclusion of an updated 61MP Exmor R BSI CMOS sensor and enhanced BIONZ X image processor, which afford impressive imaging results with marked smoothness, a 15-stop dynamic range, and, of course, speed.
Up to 10 fps shooting is possible along with the ability to record UHD 4K30 video, both with support for Real-time Eye AF and Tracking AF technologies. The revised sensor design uses a Fast Hybrid AF System, with 567 phase-detection autofocus points, for notably fast and accurate focusing performance. Despite being such a high-resolution sensor, it is also distinguished by its flexible native sensitivity range from ISO 100-32000 for working in a variety of lighting conditions. Additionally, benefitting both stills and video operation, the a7R IV retains the 5-axis SteadyShot INSIDE sensor-shift image stabilization, which is effective to minimize the appearance of camera shake by up to 5.5 stops.

The α7R IV captures the mood of each scene and the texture of subjects.
61.0 MP2 full-frame back-illuminated CMOS sensor
The newly developed Exmor R CMOS image sensor boasts incomparable high resolution. The Back-illuminated design exhibits high sensitivity and low noise, despite an extremely high pixel count of 61.0 MP
The latest image processing engine
The BIONZ X image processing engine and front-end LSI to maximize high-resolution sensor performance and up to 15-stops of dynamic range.
Wide standard ISO 100-32000 range
Regardless of increased pixels, the α7R IV delivers the highest standard ISO 320004 and reduces noise in the low- and mid-sensitivity ranges, achieving high-quality imagery.
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. A vibration-free shutter maximizes the extremely high α7R IV resolution for crisp clear images.
Blur reducing structure
To maximize the incredible resolution available to the α7R IV the tiniest vibrations need to be suppressed — Sony re-engineered the shutter unit assembly with dampened screws to absorb any shutter shock. Combined with an enhanced image stabilizer algorithm, blur is dramatically reduced, and pin-sharp detail is reliably captured.
Shake-free remote shutter release
Remote camera operation using the 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 α7R 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 120/100fps frame rate makes it easy to track moving subjects.
The highest-level burst speed in its class
Regardless of remarkable image resolution, the α7R IV maintains its shooting speed of up to 10fps with a mechanical shutter (up to 8fps in live-view continuous shooting mode).8 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 α7R 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 the enhanced Fast Hybrid AF, the α7R IV has the ability to capture a subject in remarkable detail, delivering swift AF even in dim lighting.
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-39. 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 α7R IV can simultaneously or relay record, separate RAW/JPEG data and stills/movies and copy data between cards.
Extend shooting to professional length
The α7R 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 α7R 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 α7R IV seamlessly changes tracking targets between face and eye when the subject is a person.
Thanks to an improved algorithm, the α7R IV now supports animal eye in addition to human eye tracking13, 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.
Real-time Eye AF: evolution of portraiture
Real-time Eye AF represents the evolution of portrait shooting. This AI-aided technology provides immediate, accurate eye detection and tracking for crisp, clear focus on the subject’s face, even when capturing a fast-moving model in a photo session.
