Still shot with Pentax LX. It seems to me that all 3 lenses under the test (Quinon, Summicron-R, Planar) perform well with color negative films. I really like Quinon’s rendering of red color. Zeiss seems to have more brilliant tone in the whole image (but I tend to miss the focus in the largest aperture), while Leica R50 always performs above average without any unexpected issue.
