As to zooms, I just don't have the eye or the discipline to use them. I tend to stand where I am and zoom without considering whether I should move to get a better shot. The primes force me to either move or change lens, which is enough hassle to make me think seriously about moving for a split second.
Some go fishing, I go photographing ! Sometimes I get small fishes and sometimes a big one... But the pleasure is still the same ! "What can I do, What can I write, Against the fall of Night". A.E. Housman
