I went to a gallery in Torontos distillery district today. I saw some street done with just a tele 200mm lens. I spoke to the photographer, and he said that a wide limits you in street photos. He also said that Canon zooms are as good quality as Leica primes. He also said that digi black and white is the same as film black and white.
Just don't ask me to do it. Even 50 seems too long for me for street shooting. I don't thing I have taken the 25mm Biogon off for the last three months. Here's what I have been getting - fortunately, as a hobbyist, I am in a position to ignore the "market."
