Sony 12-24mm f/4G Aperture Series @ 13mm: Pescadero Creek Side Pool (Sony A7R II)

See my Sony mirrorless wish list.

The 12mm focal length is not easy to do well.

Canon’s 11-24mm f/4L is a very fine lens, but it costs a lot more and is very large and heavy.

This aperture series with the Sony FE 12-24mm f/4 G at 13mm explores the near-to-far performance as well as what the lens can do in the outer zones and corners.

Aperture Series at 13mm: Pescadero Creek Side Pool (with Focus Stack)

Includes images up to full resolution from f/2.8 through f/13.

A two frame focus stack that corrects distortion is included for comparison with f/9 and f/13.

The about $1699 Sony 12-24mm f/4 G looks to have some high-grade attributes with some foibles. More work coming soon will explore its limits across the zoom range. But it sure is handy to have that 12-17mm range to complement the Zeiss Batis 18mm f/2.8 and Zeiss Loxia 21mm f/2.8.
