I’m kicking off my coverage of the Sony A7R IV by showing various lenses and their performance—good and bad—see Demands on Lens Performance with the Sony A7R IV are More Pronounced than I had Anticipated.
The Zeiss Loxia 25mm f/2.4 is one of the top few best of the 22 lens combinations I tested last night, but it has some field curvature behavior that is more important than ever to be aware of, that is, on a 60MP sensor.
This series evaluates the Zeiss Loxia 25mm f/2.4 on an extremely demanding target: a planar subject with exceedingly fine detail. Sony A7R IV 4-shot pixel shift was used to capture the best possible detail. This target is among the most demanding any lens can face, mercilessly showing most all lens weaknesses.
Includes images up to full camera resolution of 60 megapixels.
