Sony has just unveiled its new flagship full-frame DSLM Alpha 1, which features a 50.1 MP (effective) sensor and can now shoot 8K video in 7,680x4,320 (4:2:0, 10-bit). At the heart of the new Sony Alpha 1 camera is the new multi-layer and rear-exposed 50.1 MP Exmor RS sensor and the improved BIONZ XR processor. The latter is said to be able to process image data up to 8 times faster than its predecessor.
As with other recent Sony full-frame alphas, the sensor is found stabilised and is said to provide a maximum of 5.5 stops of stabilisation performance. The autofocus module of the new Sony Alpha 1 has 759 phase detection points and, in addition to the familiar Face and Realtime Eye AF functions for people and animals, now also offers a tracking function specially optimised for bird&s eyes. For recording, the Sony Alpha 1 has two card slots, both supporting UHS-I and UHS-II SDXC/SDHC cards as well as new CFexpress Type A memory cards.
Video features include the aforementioned 8K video resolution (via 8.6K oversampling), 4K up to max 120 fps, a 5.8K oversamplimg mode for S35 and external 16-bit RAW recording with external recorder (with simultaneous internal 4K recording). The Sony Alpha 1 is also the only Sony DSLM we know of to feature the S-Cinetone colour profile familiar from Sony FX cameras. S-Log2 and S-Log3 log formats are on board.
If you want to record internally in 10-bit 4:2:2, you can do so in 4K UHD with a maximum of 100 fps. The higher resolutions up to max. 7,680 x 4,320 are available in max. 10 bit 4:2:0. The Sony Alpha 1 uses XAVC S (H.264) and XAVC HS (H.265) video codecs including i-Frame options. The maximum data rate is 600 Mbps (with XAVC S-I 4K in 3,840 x 2,160 (4:2:2, 10Bit 60p)).
The data for the OLED viewfinder of the Sony Alpha 1 is also quite remarkable. Not only does it have a blackout-free display, which is important for photographers, but it also has a resolution of 9.44 million pixels, which is probably the highest resolution viewfinder of all DSLMs on the market. Sony specifies a viewfinder magnification of 0.9x and a frame rate of 240 bps.
The Sony Alpha 1 will be available from March 2021 at a price of approximately 7,300 euros.
