Slaba ocena ostrosci Planara moze byc zwiazana z akurat kiepskim egzemplarzem, bo Photozone pisze inaczej o tym
The Zeiss lens produced superb resolution figures in our MTF lab. The center resolution is already exceedingly sharp at f/2 and the borders/corners follow on a very good level. The center quality broke the previous resolution record at f/4 - it's safe to state that the lens is easily outresolving the 21mp of our test DSLR here. The global peak performance is reached at f/5.6 with an excellent quality across the image frame. Diffraction effects have a higher impact from f/11 onwards but the quality is still very good at f/16. Field curvature is a non-issue.
Mieli naprawde swietne wyniki. :-D
