I went out on Saturday for some street photography (mainly also to try out some Fujicolor 200). I took a Bessaflex with a 35mm Flektogon and a 50mm Zeiss Ultron, both of which are gorgeous lenses. I hardly used the Ultron - 50mm is just a bit too long, and all my 35mm shots are just a bit wide.
As I like the 40mm Canon F2.8 pancake for focal length and size, I was wondering about the Voigtlander 40mm f2 Ultron for Nikon - fast, small and seemingly well built, and well rated.
Looking around there appear to be three versions - the SL aspherical, the SL II and the SL II S.
Is there any fundamental difference in results between them, and how generally do users rate them?
Help, as always, much appreciated!
