• Digital audio interface for superior sound: A digital audio interface delivers outstanding audio quality with compatible audio devices connected via the Multi Interface Shoe. Pristine digital audio is delivered directly to the camera.
• Heat-dissipating structure for extended recording: A newly developed heat-dissipating structure prevents overheating during continuous recording without increasing body size. Record 8K/30p or 4K/60p video continuously for up to 30 minutes.

The cinematic S-Cinetone look

The α1 includes the same S-Cinetone colour matrix that produces beautiful colour and skin tones in the VENICE, FX6, and other Cinema Line cameras. S-Cinetone delivers natural mid-tones that are essential to healthy-looking skin colour, plus soft colours and gorgeous highlights, responding to a growing need for more expressive depth.

"Active Mode" image stabilisation

A new Active Mode dedicated to movie shooting makes 5-axis optical image stabilisation highly effective for handheld shooting. It uses the BIONZ XR engine's real-time processing capability to apply optimum compensation in all formats, including 4K. All of this is realised without compromising the compact size and mobility of the α system.

Control, reliability

• High-performance electronic viewfinder: The 9.44 million-dot (approx.) OLED viewfinder in the α1 offers the highest resolution in the industry at this time. It features 0.90x magnification with a 41 ° FOV for a clear, wide view, and an updated structure that results in a 25-mm-high eyepoint. A 240fps refresh rate with UXGA FOV is another world-first, for a clear view of fast action.

• Panning shots with an electronic shutter: Using an electronic shutter at low shutter speeds can reduce display response, making it difficult to follow fast subjects. Turn [Low Frame Rate Limit] ON to improve display response and allow panning shots.

• Seamlessly switch full-frame and APS-C formats: M and S size images have the same number of pixels and AF area in the full-frame and APS-C modes, so you can switch seamlessly between full-frame [M:21MP] and APS-C [M:21MP] while shooting the same scene.
• Separate settings for stills and movies: A subset of the settings now changes according to the selected mode. This is ideal when you want to use different aperture, shutter speed, and other settings for shooting stills and movies.
• New menu structure: Another feature requested by professional photographers and videographers: a revised menu structure for easier navigation, and touch-responsive menu operation for more intuitive control.
