See my Sony wish list and get Sony A7R III and Zeiss Loxia at B&H Photo.

This aperture series at 105mm looks at the Sony 24-105mm f/4 G OSS on a planar target that gives many lenses (well, most) at best a passing grade, but rarely an 'A'. It is a very difficult challenge for a lens because it not only mercilessly reveals any symmetry issues, but the target is also planar (flat), so field curvature can wreak havoc with mid/edge/corner sharpness

Sony 24-105mm f/4G OSS Aperture Series @ 70mm: Mosaic

Includes images from f/4 through f/11 at up to full camera resolution, with commentary and large crops.

Correcting distortion this strong will automatically degrade resolving power and micro contrast in the areas that must stretch-apart the pixels the most (e.g., if 1.0 pixels become 1.2 pixels).

f5.6 @ 1/60 sec, ISO 100; 2018-01-20 08:35:33
