Is it true that the Sony a1 or Alpha 1 could be the best camera Sony has ever made? In this article we will discuss what this camera can really do and what this camera is truly capable of. According to Sony, the Alpha 1 can do just about anything with its rare combination of speed, high-resolution stills and high-end 8K video.

Sony a1 processor


At the heart of any camera is the sensor and processor, the a1 or Alpha 1, features a newly designed 50.1MP full-frame Exmor R BSI CMOS sensor which produces incredible image quality, and is powered by dual Bionz XR image processing engines which helps produce 30fps continuous shooting. 

This combo helps accommodate the camera’s ability to shoot video at up to 8K at 30fps and 4K at 120/60fps and also, recording in multiple raw formats including S-Cinetone and S-Log3.

The Sony Alpha 1, or a1, is probably the most versatile professional camera there is.


Other key specifications are as follows:

  • 50MP ‘stacked’ full-frame CMOS sensor
  • 30 fps burst shooting with electronic shutter (lossy compressed Raw/JPEG only)
  • 8K/30p video recording with Log and 4K Raw video out over HDMI
  • 1/400 sec flash sync with mechanical shutter (1/200 sec with electronic shutter)
  • 9.44M-dot OLED electronic viewfinder with 0.9x magnification
  • 3.0″ tilting touchscreen with 1.44M-dot resolution
  • Full-size HDMI port, headphone / mic ports, USB-C port with 10 Gb/s transfer speeds, ethernet port
  • Dual UHS-II / CFexpress Type A card slots
  • CIPA rated to 530 shots with rear LCD (430 through the viewfinder)
  • Weather-sealed body
  • 737g (1.62 lb)

The only real downside with the Sony A1 is that it’s an extremely expensive camera. It costs around $6,500 / £6,499 / AU$10,499 for the body only. But other than that, the Sony Alpha 1 is truly a remarkable camera.
