Dpreview tested the 8K feature of the Sony A1:

8K might sound like it’s completely unnecessary, given how few people have 8K displays and the diminishing returns that higher-resolution panels show at comfortable viewing distances. However, just like the early days of 4K, there’s a distinct value to being able to capture footage at higher resolution than you intend it to be viewed.

In this instance, most of the footage has been downsampled to 4K resolution, which should give higher levels of detail than you’d get from native 4K capture. The higher resolution also offers the possibility to crop and pan within the larger 8K region, while still offering at least 4K quality. Such examples are marked in the video.

Lenstip tested the new lens and writes:

Like in the case of the Sony FE 35 mm f/1.4 GM, tested by us not so long ago, our summary will be short. It seems Sony is on a winning streak – they managed to launch another outstanding lens on the market. It deserves our ‘Editor’s Choice’ badge just for the way it performs at the maximum relative aperture but the list of its assets doesn’t end here. This list is really long and impressive. A round of applause!

Pros:

  • solid and sealed mechanical construction,
  • sensational image quality in the frame centre up from the maximum relative aperture,
  • very good image quality on the edge of the APS-C sensor,
  • good image quality on the edge of full frame,
  • properly corrected longitudinal chromatic aberration,
  • slight lateral chromatic aberration,
  • moderate distortion,
  • decent coma correction,
  • moderate vignetting on the APS-C sensor,
  • good performance against bright light,
  • very pleasant out-of-focus areas,
  • quite fast, silent and accurate autofocus.

Cons:

  • high vignetting on full frame.
