Sony a1
2021 · 50.1 MP · 35.9 x 24 mm · 737 g · 8K 30p (7680 x 4320)
The Sony a1 is Sony's flagship full-frame camera for professionals in sport, wildlife and news who also need high resolution. It combines a 50.1 MP sensor with bursts of up to 30 fps on the electronic shutter, 759 phase-detection autofocus points, and 8K video at up to 30p. In-body stabilisation is rated at 5.5 stops and the body weighs 737 g. Against the a7R V it gives up some resolution (50.1 MP against 61 MP) in exchange for three times the burst speed, which makes it the choice when both detail and speed count.
