Sony Alpha 7R IV

The Sony Alpha 7R IV (ILCE-7RM4) is a landmark ultra-high-resolution full-frame mirrorless camera created by Sony for landscape, commercial studio, architecture, fine art, and portrait photographers seeking unprecedented resolving power in a portable 35mm system. At its heart lies the world's first 61.0-megapixel effective back-illuminated Exmor R CMOS image sensor, coupled with the advanced BIONZ X processing engine and front-end LSI. This state-of-the-art configuration produces breathtaking 14-bit RAW tonal transitions, an expansive 15-stop dynamic range at low sensitivities, and superior signal-to-noise performance across detailed scenes.

The photographic power of the Sony Alpha 7R IV is elevated by a Fast Hybrid AF system featuring 567 focal-plane phase-detection points covering approximately 74% of the image frame, complemented by 425 contrast-detection points. Driven by sophisticated AI algorithms, the camera delivers Real-time Tracking and Real-time Eye AF for humans and animals in both still and video shooting. The Sony Alpha 7R IV delivers continuous burst shooting at up to 10 frames per second with full AF/AE tracking at 61 MP, while its Pixel Shift Multi Shooting mode composites 16 shifted exposures to produce massive 240.8-megapixel images with extraordinary color fidelity and moire elimination.

Crafted to excel in demanding field environments and high-paced studio workflows, the Sony Alpha 7R IV features a 5.76-million-dot UXGA OLED Tru-Finder EVF with 0.78x magnification, a tilting touchscreen LCD monitor, and an upgraded magnesium alloy body with enhanced dust and moisture sealing. It integrates a 5-axis SteadyShot INSIDE stabilization system providing up to 5.5 stops of compensation, dual UHS-II compatible SD card slots, dual-band 2.4/5GHz Wi-Fi for wireless tethering and high-speed background FTP transfer, and a USB-C 3.2 Gen 1 port for fast wired tethering. The Sony Alpha 7R IV sets a definitive benchmark in high-resolution photography.
