Check out review articles and download hi-res photos
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.
61.0-megapixel full-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 aimed subjects.
The newly developed Exmor R CMOS image sensor boasts incomparable high resolution. Back-illuminated design exhibits high sensitivity and low noise, despite extremely high pixel count of 61.0 MP.
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-stop dynamic range at low ISO sensitivity.
Regardless of increased pixels, the α7R IV delivers the highest standard ISO 32000 and reduces noise in the low- and mid-sensitivity ranges, achieving high-quality imagery.
Factors maximizing superb resolution
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.
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 α7R IV resolution for crisp clear images.
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.
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 utilize 61.0-megapixel full-frame shooting, for example, in bird photography that tends to require cropping editing to magnify captured images.
Real-time Eye AF represents the evolution of portrait shooting. This AI-aided technology allows 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. The photographer can concentrate on composition—for a smoother workflow that pros can count on.
Wireless and wired connective solutions for demanding pros
The α7R IV supports various options for PC Remote functions and means of data transfer including 5 GHz Wi-Fi. Take full advantage of more choice and convenience in remote shooting operation and data backup.
Use PC Remote to control the α7R IV or transfer data to PC via Imaging Edge™ 'Remote' software application (ver. 2.0 or later). Faster 5 GHz Wi-Fi option is available for more shooting flexibility.
Use SuperSpeed USB 5 Gbps (USB 3.2) compatible USB Type-C® port for faster transfer with new algorithm for wired PC Remote shooting. Transfer large uncompressed RAW images smoothly without workflow interruption.
To meet pro needs for prompt delivery, the α7R IV supports FTP background transfer during and after shooting for JPEG and RAW file delivery. Up to nine FTP servers can be assigned in advance.
Elevate your photography with the Imaging Edge desktop applications. Use Remote to control and monitor shooting live on your PC screen, Viewer to quickly preview, rate, and select photos from large image libraries, and Edit to develop RAW data into high-quality photos for delivery.
Now supports compositing 16 images with Pixel Shift Multi Shooting
This renewed feature shifts the sensor in half or one pixel increments in a programmed order to capture 16 pixel-shifted images, composited into one high-precision image of approx. 240.8 MP from original data of approx. 963.2 MP (equivalent). Still images of architecture and art, etc. are reproduced in true-to-life detail, texture, color, mood, setting and 3D-like realism, with breathtaking fidelity.
Meet the rigorous autofocus demands of 4K movies with enhanced Fast Hybrid AF. You have high speed, precision and tracking performance at your command for smooth, stable AF movie shooting. Adjust AF tracking sensitivity for steady focus.
Real-time Eye AF newly supports movie shooting by detecting the subject's eyes and continuing to track one eye. As the α7R IV keeps that eye in precise focus, you can concentrate on composition.
When shooting movies, touch a subject on the LCD monitor. The α7R IV begins focusing and following with Touch Tracking. If the α7R IV spots a human eye, Real-time Eye AF activates and tracks it, too.
Digital audio interface enhances Multi Interface Shoe (MI Shoe). Use the new ECM-B1M Shotgun Microphone or the new XLR Adapter Kit to record high-quality sound with minimized deterioration.
