The Sony Alpha 1 has landed
Posted on Jan 28, 2021
By any measure, the Sony A1 looks like a sensational camera. Its resolution is 50.1 megapixels with a new full-frame, back-illuminated stacked Exmor RS sensor that works with an upgraded Bionz XR engine, which boasts eight times more processing power than the Bionz X used in the A7R IV and A9 II.
All that power is needed because the A1 can shoot at 30fps continuously for 165 JPEGs or 155 compressed Raws with AF/AE tracking. In total, the AF/AE system makes 120 calculations every second. This drops to 20fps with uncompressed or lossless compressed Raws, while these speeds are with the camera’s silent, vibration-free electronic shutter and without blackout. Rolling shutter effect can prove an issue, with electronic shutters shooting moving subjects, while flicker is a problem in artificial light. Fortunately, the A1 has the technology to deal with those potential problems.
The electronic shutter can also work with the electronic flash, making the A1 the first camera to offer this – the flash sync speed in full-frame mode is 1/200sec and 1/250sec in APS-C format. Switch to the mechanical shutter and full-frame flash sync is 1/400sec and continuous shooting is possible at 10fps.

The A1 is not all about speed, but image quality too.
