Hi everybody I want to buy a wide angle lens, a Zeiss 25mm/2.8 Biogon T ZM. The price of the Voigtlander finder 21/25 is cheaper than the Zeiss finder. Is it a good idea to use the Voigtlander finder with this Zeiss lens? What about the 24 mm Elmarit whit this finder even there is a small difference? Which lens is the best, Elmarit,Biogon or the 25/4 Color-Skopar for you?
