Sony α7 IV

The Sony α7 IV (model ILCE-7M4) is a full-frame mirrorless interchangeable-lens camera manufactured by Sony. It was announced on 21 October 2021 as the successor to the Sony α7 III. Featuring a new 34.1MP (approx. total) back-illuminated CMOS sensor inside, latest BIONZ XR™ image processor, Real-Time Eye AF tracking and 4K 60p video with Super 35mm mode. It was succeeded by the Sony α7 V, announced on 2 December, 2025.

Features The camera features several advancements from its predecessor the Sony α7 III, also incorporating some pro features from the high-end Sony α1.

33 MP (approx. effective) full-frame BSI-CMOS sensor 759 phase detection autofocus points and 425 contrast detection autofocus points Continuous Eye-AF tracking for Human, Animal & Bird Improved UI layout (new menu structure) compared to its predecessor Closed mechanical shutter function when the camera is turned off (feature debuted in α1) Flip 3-inch LCD vari-angle touchscreen with 1.04 million dots 3.69-million-dot OLED Quad-VGA resolution 120 fps refresh rate EVF, 1.6× resolution compared to α7III 5-axis optical in-body image stabilisation with a 5.5stops of shake reduction 10 fps continuous burst shooting (mechanical or electronic silent shutter) with compressed Raw, 6 fps with Uncompressed Raw Live stream through the USB Type-C connector in 4K(15 fps) or FHD(60 fps) Up to 4K 30p video recording with 7K oversampling available in full-frame mode, 4K 60p recording in Super 35mm mode 15-stop dynamic range Slow & Quick motion features up to 120 fps Battery life with NP-FZ100 is rated at approximately 580 images using LCD screen and approximately 520 images using EVF according to CIPA rating method Native ISO range is 100-51,200, extended ISO range is 50-204,800 10-bit HEIF image option (using .heic container) Weather sealed, magnesium alloy body No built-in flash Multi Interface (Mi Shoe) shoe with Sony's unique metal shoe Supports 4 different video file formats (XAVC HS 4K, XAVC S-I 4K, XAVC S 4K, XAVC S HD) Dual SD card slots, single CFExpress Type A slot (SLOT 1)

Dynamic range and color independent testing Independent testing by Gerald Undone using Imatest software and a Xyla color range chart demonstrates 12.8stops of dynamic range, which is approximately 1/3 of a stop better than the Sony α7S III and approximately the same as the Sony α1 It color matches fairly well with the α7S III and α1, with the α7S III leaning a bit green, the α1 a bit magenta, and this camera between the two (tested using DCS Labs -SW - CDM 28R - v15.2 A3 color chart) and with individual white balancing, the colors are very similar.

Video formats Camera is using in-house developed AVC Video Format called XAVC. The format is compressed format, achieving balanced quality and file size. Recording in color depth of 10 bits and 4:2:2 chroma subsampling is possible with Sony's XAVC codec.

All Intra-frame system that compresses each frame individually to achieve best quality. When recording 4K movies in the XAVC HS format is an optional which is using a HEVC codec (H.265) and has high compression efficiency. The camera can record movies with higher image quality than XAVC S movies but the same data volume. Camera can record in "Long GOP" codec (H.264) compression, which is compressing multiple frames to reduce file size.
