Sony a7 V Announced: New Sensor, Faster AF, and Stronger Video Features

Sony has announced the a7 V, the fifth generation in its full-frame mirrorless line, built around a newly-developed partially stacked Exmor RS CMOS sensor offering 33MP effective resolution.

Sony has announced the a7 V, the fifth generation in its popular full-frame mirrorless line. The camera debuts the updated BIONZ XR2 processor, which incorporates the AI processing unit found in Sony’s recent Alpha models. Sony says the combination improves autofocus performance, tracking reliability, colour accuracy, and overall responsiveness for both stills and video.

The company has also introduced the FE 28–70mm f/3.5–5.6 OSS II, a compact standard zoom designed to support the A7 V’s high-speed continuous shooting.

AI-Driven Performance Upgrades

Sony says the updated BIONZ XR2 engine and integrated AI unit deliver faster and more accurate autofocus. Real-time Recognition AF is rated as up to 30% more accurate than the previous generation, assisted by 759 phase-detection points covering up to 94% of the frame. The system is designed to track subjects in low-light conditions down to EV –4.0.

High-resolution RAW processing is also now supported via Sony’s Imaging Edge Desktop application, offering more flexibility for post-production workflows.

Partially-Stacked Sensor Improvements

The partially stacked sensor provides approximately 4.5× faster readout than the previous generation, helping reduce rolling-shutter distortion.

The a7 V performs up to 60 AF/AE calculations per second and offers blackout-free continuous shooting at up to 30fps with AF/AE tracking, including when capturing 14-bit RAW files. The camera also introduces a Pre-Capture function that records up to one second before the shutter button is pressed to help catch those unpredictable moments.

Video Features

The a7 V introduces additional 4K recording modes, including 7K oversampled 4K60p recording available in full-frame mode and 4K120p mode recording in APS-C mode/Super 35mm.

Full pixel readout without pixel binning enables highly detailed video recording down to the finest details.

Image stabilisation features Dynamic Active Mode, enabling smooth and stable video expression, which Sony says works even when handheld. The camera also features an Auto Framing function that automatically maintains optimal composition of subjects during recording through AI-powered subject recognition. 

New in-camera noise reduction and improved internal mic functionality ensures high-quality audio recording by reducing steady background noises, minimising interference, and maintaining natural sound.

Still Image Performance

Sony rates the A7 V for up to 16 stops of dynamic range, aiming to retain detail across highlights and shadows in high-contrast scenes.

A newly developed AI-driven Auto White Balance system analyses scenes and estimates the light source using deep-learning models. The system is designed to improve consistency and reduce manual correction in mixed-lighting environments.

Handling and Connectivity

The a7 V adds Wi-Fi 6E for faster wireless transfer and dual USB-C ports for greater workflow flexibility. Other usability updates include:

• Support for vertical-format shooting

• Adjustable electronic shutter sound

• A 4-axis 3.2in  multi-angle rear monitor combining tilt and vari-angle mechanisms

• 3.68-million dot Quad-VGA OLED EVF

• Updated grip design for improved handling

Weight is 695 grams / 24.5 ounces with battery and recording media. And it comes in at nearly the same size as its predecessor and 130 x 96 x 72 millimeters / 5.1 x 3.8 x 2.8 inches.

Battery Life and Thermal Management

Sony says the camera offers improved power efficiency, supported by a new “Monitor Low Bright” mode to extend battery runtime. Thermal management has been revised to allow longer 4K recording times, with 4K recording time @ 25°C / 77°F approximately 90 min; 4K recording time @ 40°C / 104°F is approximately 60 min. CIPA-rated battery life is approximately 630 shots when using the viewfinder.

FE 28–70mm f/3.5–5.6 OSS II

There is also the new lens to consider. The updated standard zoom is designed to take advantage of the a7 V’s continuous-shooting performance. When paired with compatible bodies, Sony rates the lens for up to 120fps AF/AE tracking. It supports coordinated image stabilisation, maintains autofocus performance while zooming, and includes breathing-compensation support.
