About this item

• Sony’s extensive high-performance G Master line work with the 50.1 megapixel*1 Exmor RS image sensor and BIONZ XR image processing engine to create deep, lifelike, high-resolution rendering. The sensor’s high pixel count means that resolution is still a very impressive 21 megapixels (approx.) when shooting in APS-C mode or cropping to APS-C size after shooting.
• The massive volume of data from the 50.1 megapixel*1 full-frame Exmor RS image sensor is processed in real time by Sony’s BIONZ XR image processing engine. An advanced AI processing unit applies high-level subject recognition to reliably recognize a wide range of subjects. These state-of-the-art technologies make it easy to capture even the most challenging subjects in extraordinary resolution, with blackout-free viewing and full AF/AE tracking at up to 30 fps. *2
• The α1 II features a dedicated AI processing unit that helps to recognize people more accurately based on human pose estimation and supports recognition of a wide range of subjects other than people, such as animals, vehicles and insects*5, with high accuracy. This results in a dramatic improvement in Real-time Recognition AF and Real-time Tracking capability, and higher overall AF performance.
• High-speed continuous shooting at up to 30 fps*2 with full AF/AE tracking is possible at a stunning 50.1 MP*1 resolution, with up to 120 AF/AE calculations per second*12 on the data from the image sensor. Blackout-free shooting with no loss of viewfinder image allows seamless framing and capture of the subject as if viewed with the naked eye.
• 4K (3840 x 2160) movies can be cropped and edited from 8K source footage with overwhelming resolution from 8.6K oversampling. 8K 4:2:2 10-bit XAVC HS recording with optional Full HD proxy is available, as are 4K recording in XAVC HS, S, or S-I formats in full-frame, or Super 35mm size oversampled from 5.8K with full pixel readout and no pixel binning. XAVC S-I allows recording at up to 600 Mbps for outstanding image quality.
• Selectable RAW image size and quality, Compressed RAW images can be continuously shot at up to 30 fps. For easier handling, as well as L, Lossless Compressed RAW, JPEG and HEIF images are also available in M and S sizes with the same numbers of pixels whether shot in full-frame or APS-C mode, enabling seamless mode switching while maintaining resolution.
• "High sensitivity, low noise, and wide dynamic range, Feedback from professionals has been taken into account to create noise reduction that is highly effective without sacrificing image detail, so users can shoot clear images of indoor sports at mid to high sensitivity without hesitation. Dynamic range at lower sensitivities is a wide 15 stops12 for smooth, realistic gradations. [1] α1, ISO 6400, 1/1600 s, F2.8 [2] α1 II, ISO 6400, 1/1600 s, F2.8"
• Consistently accurate exposure and colour, Exposure and colour reproduction are notably improved compared to the α1, with exposure optimised for detected faces in stills and movies, and exposure stability improved by approximately 20%13 even when the face is backlit, over-illuminated in sunlight, or not facing the camera. White balance is accurate even for subjects in shade.
