The camera also benefits from 5-axis in-body image stabilization for up to 5.5 stops of shake compensations, with an optical active mode available to give stabilization performance a bump during video recording.įraming up can be undertaken using the 3.68-million-dot OLED viewfinder or 3-inch, 1.03-million-dot side-opening, vari-angle touch monitor. The a7 IV can record 4K/60p video in Super 35 crop mode, or 4K/30p with 7K oversampling in full-frame mode at 10-bit 4:2:2 detail, and there's support for the BT.2020 color gamut, as well as H.264 and (the more efficient) H.265 long-GOP compression. The real-time eye tracking can now zero in on birds and animals for still images and video too.
Its hybrid autofocus makes 759 phase-detection AF points available, which cover almost 94 percent of the image area, and the face and eye detection for humans gets a 30-percent improvement on its predecessor.

The a7 IV comes with a 33-MP back-illuminated Exmor R CMOS full-frame (35.9 x 23.9-mm) image sensor that's paired with the latest Bionz XR processing engine, for 15 stops of dynamic range, ISO light sensitivity of 100 to 51,200 that can expand down to ISO50 and up to ISO204,800, and continuous shooting at up to 10 frames per second with AF/AE tracking. Now the company has pulled back the curtain on generation four, which boasts a newly-developed 33-megapixel image sensor and performance improvements across the board. Back in 2018, Sony raided its flagship cameras for the third generation of the a7 full-frame mirrorless camera.
