In general, I do not find the normal lens especially desirable, functionaly or aesthetically. The angle of view and depth of field characteristics do not seem favorable to me in interpreting space and scale. In my experience, lenses of shorter or longer focal length are usually preferable in an aesthetic sence. I frequently find that the "normal" concepts and performances are not as exciting as those that make an acceptable departure from the expected reality. A short-focus lens makes possible exciting near-far images, exaggerating the differences of subject scale and depth. A long lens favors more accurate "drawing" of the features of portrait, and gives a quasi-abstract impression of two-dimensionality with distant objects.
