Hi,
I'm looking at getting a Summitar and was wondering whether anybody can shed light on the two variants, namely the round aperture bladed version approx. pre 1950 and the later type with the hexagonal arranged aperture. Generally the latter version seems to be a little less expensive and less sought after if my observations are correct.
Both lenses opened at f2 there is clearly no difference in aperture shape but any smaller setting then does the hexagonal opening perhaps provide a little less appealing bokah for instance? Or perhaps there may be other discernible differences?
Thanks in advance.
