As a prelude to a very interesting study of the Sony A1 vs the Sony A7R IV, I show this series...
This series from f/2 through f/11 evaluates the Voigtlander 65mm f/2 Macro APO-Lanthar at close range for overall rendition, sharpness, etc.
Includes images up to full camera resolution from f/2 through f/11 along with a 4-frame focus stack at f/6.3, for a stunningly detailed capture.
As far as I can tell, my eyes says that it doesn’t get any better than this with any camera or lens on the market today. Color, non-existent noise, superb detail, etc. What a disappointment that Fujifilm has screwed the pooch with the Fujifilm GFX100S with the inexplicable absence of a 4-shot pixel shift—this Sony A1 quality beats any single-shot medium format capture.
