The α1 II is Sony’s professional mirrorless camera with a 50.1 MP stacked full-frame sensor. It offers 30 fps blackout-free shooting with the electronic shutter, pre-capture, recognition of humans, animals, birds, insects and vehicles via a dedicated AI processing unit, 8.5 stops of in-body stabilisation at the centre and 8K 30p video. It has a four-axis 3.2-inch screen, a 9.44-million-dot 240 fps viewfinder, two CFexpress Type A / SD slots and 2.5 GbE wired networking. Owners love the autofocus and image quality and mostly criticise the price and the small body for large hands.

All 10 reviews on Best Buy give 5 stars; nine carry the incentive tag, eight are verified purchases and one is a Best Buy employee. Owners most praise autofocus and tracking (especially improved bird AF versus the original α1), low-light detail, the 30 fps stacked sensor and the articulating screen for low-angle landscapes; CarlW notes features the original α1 lacked, OmerM says it combines the strengths of the α7R V and α9 III. Criticism is limited to price, a small body for large hands (a grip is said to fix it) and the Best Buy delivery and packaging experience. No faults or software issues are reported; ownership ranges from two weeks to one month.
