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 61.0MP1.
The BIONZ X image processing engine and front-end LSI to maximise high-resolution sensor performance and up to 15-stops2 of dynamic range.
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 stabiliser algorithm is optimised to maximise 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. 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 supressed, 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.
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.
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 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 61.0MP 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 into 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.
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 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.
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. ‘Focus Priority in Aperture Drive’ option is for more accurate focusing in dim lighting and when aperture is stopped down.
Because 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.
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.
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 your subject's 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 use of Real-time Eye AF with Real-time Tracking11, which responds to dynamic subject motion. This teamwork enables tracking accuracy for comfortable portrait shooting.
Wireless and wired connective solutions for demanding prosThe α7R IV supports various options for PC Remote functions and means of data transfer including 5GHz14 Wi-Fi. Take full advantage of more choice and convenience in remote shooting operation and data backup.
