This series from f/2 through f/8 evaluates the diminutive Zeiss Loxia 35mm f/2 Biogon on an extremely demanding subject that makes mincemeat of most lenses, mercilessly revealing every weakness, lack of symmetry, etc. Most lenses require f/5.6 or f/8 to sharpen the whole mosaic.
The Loxia 35/2 is a rangefinder design adapted (tweaked by Zeiss) for mirrorless use. It is not a high performer wide open, but its intrinsically superb optical design can shine when stopped down, so how does it do on the 60MP Sony A7R IV?
Includes images up to full camera resolution of 60 megapixels.
