α7R IV 35 mm Full-Frame Mirrorless Camera with 61.0 MP ILCE-7RM4
Ever more inspiring
Enter a whole new world of photographic expression with incomparable image quality and processing speed. A powerful new choice joins the α7R series with ever more advanced connectivity and enhanced reliability demanded by pros.
The 61.0-megapixelfull-frame Exmor R™ CMOS sensor combined with BIONZ X™ imaging engine delivers unprecedented resolution, fine gradation and low noise to open entirely new dimensions of detail just as pro photographers expect. The α7R IV captures the mood of each scene and the texture of subjects.
61.0-MP 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 maximise high-resolution sensor performance and up to 15-stops of dynamic range.
Factors maximising superb resolution
In-body 5-axis image stabilisation
The in-body 5-axis image stabiliser algorithm is optimised to maximise 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. A vibration-free shutter maximises the extremely high α7R IV resolution for crisp clear images.
To maximise the incredible resolution available to the α7R IV the tiniest vibrations need to be suppressed, so Sony re-engineered the shutter unit assembly with dampened screws to absorb any shutter shock. Combined with an enhanced image stabiliser 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 maximises the image sensor's high resolution.
5.76-million-dot UXGA OLED Tru-Finder
The 5.76-million-dot electronic viewfinder reproduces fine detail with approx. 1.6 times higher resolution than the α7R III. You can select the High quality mode for high-precision yet natural realism while suppressing moiré and jaggies for better concentration. The smoother image with 120/100fps frame rate makes tracking moving subjects easy.
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). 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 as 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 utilise 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 underlit 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 aperture is stopped down.
Shoot up to 68 images continuously
Because the buffer memory size is 1.5 times larger, the camera maintains a burst shooting speed of up to approx. 68 images. With the APS-C shooting mode, you can shoot approximately three times more photos than with the 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 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 the Face/Eye Priority in AF function, the α7R 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 α7R 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 favourite 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 a subject's face, even when capturing a fast-moving model in a photo session. The photographer can concentrate on composition—for a smoother workflow that pros can count on.
Instant focusing on an eye
When Face/Eye Priority in AF is on, simply half-press the shutter, press AF-ON button, or an assigned custom button. The camera takes care of focusing on your subject's eye.
Right/left eye selection to meet your needs
Now you can even select a specific eye—left or right—before or during shooting via a custom button. Eye selection allows you to focus on composition, lighting and other details.
Works with Real-time Tracking for eye-catching portraits
You can combine Real-time Eye AF with Real-time Tracking, which responds to dynamic subject motion. This teamwork enables tracking accuracy for comfortable portrait shooting.
