Sony's smart AI-based Real-time Tracking

Sony's unique subject recognition algorithm uses colour, pattern (brightness) and subject distance (depth) data to rapidly process spatial information in real time. AI is used to detect and track the eyes and face of the subject (human, animal or bird) with extremely high precision. Just select the subject to track, then leave it to the camera.

Improved Real-time Eye AF

Keep the targeted eye in focus so you can concentrate on composition. The high speed of the latest image-processing engine provides a significant boost to Real-time Eye AF performance, even when the subject is looking up, down or sideways. It is also possible to use Touch Tracking to initiate Real-time Tracking of any subject in the frame, simultaneously initiating Real-time Eye AF if an eye is detected, simply by touching the screen.

Pet photos made easy: Fast, accurate focus for difficult animal shots

By setting the camera's subject detection type to "Animal" in advance, you can automatically detect and track an animal's eyes, for greater success in both wildlife shots and photos and movies of your pets at home. Animal-eye detection has been improved, with reliable tracking and accurate focus even when the animal's face is upside down.

High-capacity Z batteries and USB Power Delivery

The α7 IV relies on a high-capacity Z battery (NP-FZ100), along with external power options that include USB power supplies and AC adapters. Battery drain can be minimized by adding a high-capacity mobile battery for outdoor shooting. A USB charger or mobile battery that supports USB PD*11 can be connected to the camera's USB Type-C® port, for extended recording.

*11 USB charging and power delivery are only supported via the USB Type-C® terminal. A battery must be installed in the camera when supplying USB power. The internal battery may drain even if USB power is supplied, depending on the adapter used and camera operating conditions.

Heat management

To allow extended continuous recording, efficient heat dissipation is provided by Sony’s proprietary Σ (sigma)-shaped thermal mounting. The mounting, which is also used on flagship models, is constructed from a graphite material with excellent thermal conduction properties. This structure allows the image sensor, a major source of heat inside the camera body, to move freely during image stabilization while heat is efficiently dissipated.

Dual media slots, with CFexpress Type A support

Dual media slots allow you to continue shooting even if one memory card fills up. One of the slots supports high-performance CFexpress Type A cards and both slots support UHS-I and UHS-II SDXC/SDHC cards. With their fast write speeds, CFexpress Type A cards*12 are particularly suited to high-speed continuous still shooting, as well as high-resolution, high-bitrate 4K movie recording.

*12 CFexpress Type B memory cards are not supported.

Reliable, robust engineering

Sony has improved the dust and moisture resistance of the α7 IV to provide outstanding reliability, even in challenging outdoor shooting environments. Design refinements include more sealing at body seams and the battery compartment cover (compared to the α7 III), a redesigned lens lock button and extra cushioning around the mount. A lightweight, high-rigidity magnesium alloy used for the camera's top cover, front cover and internal frame provides excellent durability.

Applying Sony's plan to the α7 IV

The α7 IV is no exception as Sony works to help preserve the environment. As with other new Sony products, the entire environmental lifecycle of the α7 IV has been considered, through development, production, packaging and logistics. High-performance recycled—and recyclable—plastic is used for various camera body components, alongside more recyclable packaging. Our production sites also leverage renewable, large-scale solar generation to reduce production energy impacts.
