刚刚发现Winogrand专门考虑过这个问题,他觉得他看到的是21mm,但离近了实在变形太 大, 所以才用了28mm: Winogrand: Ideally, I wish I had a lens that took in my whole angle of vision, without mechanical distortion – that’s the headache with these things. Ideally, that would probably be the most interesting to work with. The 28 is probably where the mechanical distortion is least limiting – much less limiting than a 21. It’s closest to the angle of attention. It’s pretty close to at least my angle of attention. Probably the 21 is more so, but its just extremely limiting. You have to use it very carefully. Moderator: If you tilt it at all, you get very strange angles … Winogrand: Well, it’s not a question of tilting; the minute you get in the center of people, a little bit close, you get another kind of nonsense happening, that falling over. In the end, those pictures wind up being primarily about what the lens is doing. If there was a 21 that didn’t behave that way, I’d probably use it.
