This is from my replacement Sony FE 70-300G lens where I am most interested in the central area shot wide open at the long end.

The entire 30”x48” test surface is approximately 34 feet away. There is a red outlined insert of the CENTRAL USAF-1951 target shown at 100%.

Out of the 42MP image those horizontal and vertical ‘1-3’ triplets exist in a roughly 9 pixels square box on a side. On the target itself the individual lines are approximately 0.25mm think.
False color is appearing on these triplets and smaller, presumably due to Moiré. At this point the 43MP FF sensor is the limiting factor.

My test images were processed from RAW using default settings in ACR except for color balance reset to 2750K and lens profiles checked. There was no exposure value compensation but in Photoshop levels were tweaked to re-set the black point a bit.

For comparison purposes, on the right side at 100% and outlined in green is the same area but taken with the Sony SAL 70-300G/LA-EA3 on the same camera, lighting and settings.
