Thank you for all this precision, I have in small telephoto lens on my RD-1 a hexanon 50 f2 which gives me completely satisfaction, but I look more opened (for the portrait). A MS-MODE 50 1.3 in the ideal, but it seems untraceable... J-3 would thus be an interressante temporary solution!
As for focal shorter digital, I would tend to prefer recent optical formulae not?
But this J-12 (without trap with small strip of shutter) seems to me nevertheless suitable.
Ps:Are any other formulae "old" known to be successful on an epson (between 21 and 28mm)?
