Sony has launched the Alpha 7R IV (or a7R IV), its latest 35-millimeter full-frame camera. It is the first such product to feature the new, back-illuminated, Exmor R CMOS sensor with a 61.0MP resolution. The a7R IV is also capable of professional-grade 4K video, an APS-C mode and USB 3.1 Gen 2 transfer speeds via a type C port.

Sony has packaged a trailblazing 61.0 MP resolution into the a7R IV, its latest 35mm full-frame camera. It is powered by a back-illuminated Exmor R CMOS image sensor, enhanced further with the latest-generation BIONZ X image processor. Besides its ultra-high pixel count, the a7R IV has a 15-stop dynamic range at low sensitivities in order to deliver next-generation detail in terms of features such as shadows.

The a7R IV also continues to support its ground-breaking new resolution in high-speed continuous shooting. It can snap up to 68 images in this mode at up to 10 fps with full autofocus (AF) or auto-exposure (AE) tracking. On the other hand, it also has an APS-C mode that cuts images down to high-quality 26.2MP shots. 

The new Sony full-frame camera also supports professional grade 4K recording, with a complete pixel readout in Super 35mm mode. It can also exploit real-time Eye AF. The a7R IV also features advanced real-time tracking and real-time Eye AF for still image recording.

The camera's body is equipped with a ultra-XGA OLED Tru-Finder electric viewfinder. Each a7R IV core unit was also designed with an improved grip and a compact lightweight body. It also has Wi-Fi and a USB type C port for enhanced transfer speeds. Accordingly, it is compatible with a number of new Sony photo- or data-focused accessories, including the XLR-K3M 3.5mm port adaptor kit and the ultra-fast MRW-S3 USB hub.

The Sony a7R IV is up for pre-order now on for US$3498. This price is for the camera body alone; its applicable lenses and accessories will be sold separately.
