christoph_d Posted February 3, 2011 Share #1 Posted February 3, 2011 Advertisement (gone after registration) Just out of curiosity: I noticed that on my Summaron 2:2.8/35mm the aperture has only click stops at full stops (2.8, 4, 5.6, etc). Is this normal? Is there an evolutionary trend from the "unclicked" early lens designs to full stops to half stops (to the 1/3 stops of the Zeiss lenses) ?
