I liked different lenses for different times. I am fond of the telephoto lens, as I am of the normal 50 mm lens. I had at one point a 150 mm lens and I was very fond it. I liked what it did. I experimented a lot. Sometimes I worked with a lens that I had when I might have preferred another lens. I think Picasso once said that he wanted to use green in a painting but since he didn't have it he used red. Perfection is not something I admire. [Laughs]. A touch of confusion is a desirable ingredient.
