Thank you all.
dominikkolendo : WHy do you find the Takumar useless on digital? Because of its optical qualities and/or you don't feel confortable with the focal length?
bassek: Thanks you for this suggestion. It will read about it.
interested_observer: Wow your list is impressive. However I would like a 35 and not 28 or 24 because I want 35mm on film and 50mm on DSLR. Thus I keep the Cosina and the Zeiss under observation
.
Schmidlapper : I am looking for a 35mm ... I don't want to start a LBA looking at 24 but if I want 35mm on DSLR...
baro-nite: Yes the lenses seem to have the same optical formula (maybe SMC coating in the last versions) but they have different ratings in the database : 8.87/39 versus 9.75/20. I think this is not a negligible difference
nono : Thanks for the picture. Did you try it on a film SLR?
oxidized : Thanks for the suggestion
