Sony's new A7R IV is the first camera to offer a full-frame (35mm) 61-megapixel sensor. The camera also sports 15-stops of dynamic range, 10fps continuous shooting with AF / AE tracking, 5-axis in-body image stabilization and Eye AF that works for both stills and video.
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 latest image processing engine
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.
Wide standard ISO 100-32000 range
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.
In-body 5-axis image stabilization
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.
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. Vibration-free shutter maximizes extremely high α7R IV resolution for crisp clear images.
Blur reducing structure
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.
Shake-free remote shutter release
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.
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). 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 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.
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-3. 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 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.
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.
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. The photographer can concentrate on composition — for smoother workflow that counts with pros.
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 favorite pets at home when an obstacle comes into view or the camera's horizontal/vertical orientation often changes.
Instant focusing on an eye
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.
Right/left eye selection to meet your need
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 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.
Wireless tethered shooting for flexible setting
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.
Even faster PC Remote with wired connection via USB
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.
Support for FTP background transfer
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.
For full-scale flash photography
Release time lag is minimized for smooth, responsive flash photography, with continuous flash shooting at up to 10fps. Select slow sync or rear curtain sync with wireless off-camera flash for enhanced versatility.
Standard sync terminal
A standard sync terminal enables convenient synchronization with studio flash units and other external lighting equipment to establish desired lighting setting in studio photography.
Steadfast AF tracking for stunning movies
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.
Digital audio interface for clear sound recording
Digital audio interface enhanced with 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.
