Sony ILCE7RM4A/B Alpha 7R IV: 61MP Full Frame Mirrorless Camera

The Sony Alpha 7R IV pairs a world-first 61MP full-frame back-illuminated Exmor R CMOS sensor with the processing power to shoot at up to 10 frames per second without sacrificing resolution. That combination makes it a compelling choice for photographers who need extreme detail — landscape, architectural, studio, and fine-art shooters will benefit from the ability to produce massive prints or crop aggressively while retaining clarity. The 15-stop dynamic range and 14-bit uncompressed RAW output ensure that shadows and highlights carry usable information, giving extensive room for tonal adjustments in post-production. An ISO range of 50 to 102,400 extends its usefulness from bright daylight into challenging low-light situations.

Autofocus performance is anchored by Sony's Real-time Tracking system, which locks onto subjects and follows them across the frame, complemented by Real-time Eye AF that works on both humans and animals in stills and video. The 5.76 million dot UXGA OLED Tru-Finder viewfinder provides a large, sharp preview that makes manual focusing and composition precise and comfortable. Connectivity options include Bluetooth, Wi-Fi, USB, HDMI, and NFC, ensuring flexible tethering and file transfer workflows. Housed in a weather-sealed magnesium-alloy body using the Sony E-mount, the Alpha 7R IV is built for professional reliability in the field.
