Sony's full-frame mirrorless α7R IV reveals ever more overwhelming photographic vision, with expressive prowess once expected only in medium-format cameras and overpowering high speed in a compact body. See how its enhanced rigidity and connectivity raise your productivity. Shipping September 12, 2019.
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 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.
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.
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.
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.
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.
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-3. The ‘Focus Priority in Aperture Drive’ option is for more accurate focusing in dim lighting and when the aperture is stopped down.
Because buffer memory size is 1.5 times larger, 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.
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 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.
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 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.
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 the 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 a 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 Tracking, which responds to dynamic subject motion. This collaboration enables tracking accuracy for comfortable portrait shooting.
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.
