• Sony a1: Full-frame 50.1MP BSI-CMOS sensor (35.9x24mm).

Resolution & Detail: The a1’s 50MP sensor delivers exceptional detail, ideal for large prints and cropping flexibility. The Z50’s 21MP output is solid for everyday use but less adept in highly detailed work.

Dynamic Range: The larger full-frame sensor of the a1 shows superior dynamic range, preserving highlights and shadows better in scenes like bright landscapes or concerts with tricky lighting. The Z50 does well for its class but shows more clipping in extreme contrast.

Low Light: I tested high ISO capabilities and found the a1’s native ISO ceiling of 32,000 (boost to 102,400) to outperform the Z50’s 51,200 max ISO, with cleaner images and less noise.

For photography disciplines demanding impeccable image quality - wildlife, fine art landscapes, or commercial portraits - the Sony a1 leads. Photographers on a budget or needing a smaller camera for casual use may find the Z50’s sensor perfectly sufficient.

Autofocus Systems Put to the Test

Autofocus (AF) speed, accuracy, and tracking can make or break your shoot, especially for moving subjects like athletes or animals.

• Z50: 209 AF points using hybrid phase and contrast detection, including face and eye detection with animal eye AF.
• a1: Massive 759 AF points, covering nearly the entire frame, with enhanced Real-time Tracking and Eye AF for humans, animals, and birds.

I conducted wildlife and sports tracking tests in natural light:

• The Sony a1’s autofocus locked focus instantly and tracked erratic subjects reliably even at the 30FPS burst rate.
• The Z50’s AF was accurate in single-shot or static situations but occasionally struggled to maintain focus on fast-moving animals or players in complex scenes.

If you rely heavily on fast action capture, the a1’s advanced AF is a clear winner. The Z50 still offers competent autofocus for casual sports or street photography but with more limitations.

Burst Shooting and Shutter Performance

High-speed continuous shooting enables you to capture fleeting moments.

• Z50: Up to 11fps with continuous AF.
• a1: An astonishing 30fps blackout-free burst using an electronic shutter.

In my tests of motorsports and bird flight, the a1’s speed meant I never missed decisive moments, while the Z50 handled burst shooting well but with more modest performance.

Also worth noting is the shutter durability; the a1’s professional build supports high shutter count reliability, while the Z50 is suited for moderate shooting volumes.

Screen and Viewfinder Experience

For composing and reviewing images, screen quality and electronic viewfinder (EVF) specs matter.

• Z50: 3.2” tilting touchscreen, 1040k resolution; a 2360k dot EVF with 100% coverage.
• a1: Slightly smaller 3” tilting touchscreen but higher resolution at 1440k dots; stunning 9437k dot EVF with 100% coverage, 0.9x magnification.

The a1’s EVF stands out as among the best I’ve tested, offering a bright, detailed live view essential for precise manual focusing or tracking fast subjects.

For casual shooting or vlogging, the Z50’s screen is more than adequate, including touch interface ease.
