The Sony α7 IV is a full-frame mirrorless camera built around a 33MP back-illuminated Exmor R CMOS sensor and Sony's BIONZ XR processor, with Fast Hybrid AF across 759 phase-detection points, 5-axis in-body stabilization and 4K 60p 10-bit 4:2:2 video. Only one review cited on this page tested this generation of the camera: wedding and portrait photographer Myles Katherine, who scored it 87 out of 100, found it "intuitive" and "user-friendly", praised the dual card slots and low-light handling, and shot a six-hour wedding on a single charge. Her reservations are specific rather than general: the electronic viewfinder image "just isn't the best", there is no built-in multiple exposure function, which she calls a dealbreaker for her own work, and the battery "died really quickly" once it dropped below about 11 percent. At roughly 658 g it is a hybrid stills-and-video body rather than the lightest thing in this guide.
- — 33MP full-frame Exmor R CMOS sensor resolves noticeably more detail than the 24MP generation it replaced
- — BIONZ XR image processing engine, which Sony rates at up to 8x the processing performance of the engine it replaces
- — 0.5-type Quad-VGA OLED viewfinder with 100% coverage and 3,686,400 dots
- — Electronic viewfinder image quality underwhelms: Myles Katherine, who shoots through the finder, found "the quality of the image in the electronic viewfinder just isn't the best"
- — Multiple exposures must be assembled later in software; Myles Katherine calls the absent in-camera function "a dealbreaker" for her own work
- — Battery falls off a cliff at the end of its charge: Myles Katherine found that "once it got to about 11% battery, it died really quickly after that"
