The Sony α7R IV boasts a 35mm full-frame 61.0 MP sensor, making it Sony's highest resolution full-frame camera ever. With unprecedented resolution and 15-stops of enhanced dynamic range at low sensitivities, the Sony α7R IV combines high-speed performance and a lightweight, compact body to provide outstanding focusing performance, high-speed continuous shooting and much, much more. This powerful new choice in the α7R series offers ever more advanced connectivity and enhanced reliability for pro-level creators.
61.0-megapixel1 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 MP1.
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-stop2 dynamic range at low ISO sensitivity.
Regardless of increased pixels, the α7R IV delivers highest standard ISO 320003, and reduces noise in the low- and mid-sensitivity ranges, achieving high-quality imagery.
The in-body 5-axis image stabilizer algorithm is optimized to maximize high-resolution 61.0-megapixel1 image sensor performance. This fully supports your handheld shooting for reliability as effective as 5.5-stop4 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.
A re-examined and redesigned mechanism infixes the shutter unit to suppress subtle camera shake, and enhanced image stabilizer algorithm effectively reduces image blur. Overall, the camera's high resolution is successfully maintained.
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.
The 5.76-million-dot electronic viewfinder reproduces fine detail with approx. 1.6 times higher resolution than the α7R III. Select “High” quality mode for high-precision yet natural realism while suppressing moiré and jaggies for better concentration. A smoother image with a 120/100fps5 frame rate makes it easy to track moving subjects.
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).7 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 at approximately 26.2 megapixels even after cropping a full-frame image down into 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.
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.
Thanks to responsive enhanced Fast Hybrid AF, despite its large data handling, the α7R IV delivers swift AF even under dim lighting conditions, with remarkable ability to capture an aimed subject.
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.
Advanced AF algorithms contribute to AF precision at light levels as low as EV-38. The 'Focus Priority in Aperture Drive' option is for more accurate focusing in dim lighting and when the aperture is stopped down.
AI-based Real-time Tracking11 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 tracking12, 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.13
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. The photographer can concentrate on composition — for smoother workflow that counts with pros.
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 a subject eye.
Now you can even select a specific eye — left or right — before or during shooting via custom button. Eye selection allows you to focus on composition, lighting, and other details.
You can combine the use of Real-time Eye AF with Real-time Tracking11, which responds to dynamic subject motion. This collaboration enables tracking accuracy for comfortable portrait shooting.
Because the buffer memory size is 1.5 times larger9, the camera maintains burst shooting speed of up to approx. 68 images10. With APS-C shooting mode, you can shoot approximately three times more photos than with full-frame shooting mode.
The α7R IV supports various options for PC Remote functions and means of data transfer, including 5-GHz14 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-GHz14 Wi-Fi option is available for more shooting flexibility.
Use USB 3.2 Gen 1 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 during15 and after shooting for JPEG and RAW file delivery. Up to nine FTP servers can be assigned in advance.
Release time lag is minimized for smooth, responsive flash photography, with continuous flash shooting at up to 10fps7. Select slow sync or rear curtain sync16 with wireless off-camera flash for enhanced versatility.
A standard sync terminal enables convenient synchronization with studio flash units and other external lighting equipment to establish desired lighting setting in studio photography.
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 MP20 from original data of approx. 963.2 MP (equivalent). Still images of architecture and art etc. are reproduced in true-to-life detail, texture, colour, mood, setting and 3D-like realism, with breathtaking fidelity.
Full-frame and Super 3522 formats can be selected for 4K movie recording. Super 35-mm mode can condense approx. 2.4 times23 the amount of data required for 4K movies (QFHD: 3840 x 2160), resulting in high-detail 4K with minimal moiré and jaggies. In either mode, the advanced image processing system delivers more accurate skin tones as well as smoother highlight gradations.
The α7R IV supplies S-Log3 for better gradation from shadows to mid-tones and wide dynamic range up to 14 stops, and supports S-Gamut3/S-Gamut3.Cine wide colour space, in addition to S-Log2. Also, HLG (Hybrid Log-Gamma) picture profile delivers instant HDR workflow. Recorded movies look true-to-life — no blocked shadows or blown highlights.
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 now 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 the Multi Interface Shoe (MI Shoe). Use the new ECM-B1M Shotgun Microphone or new XLR Adaptor Kit to record high-quality sound with minimized deterioration.
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.
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.
