The fovea of the eye provides the sharpest image. Many years ago I read somewhere that the 90mm lens on a 35 subtends about the same angle of view as the fovea. [In other words, the 90mm captures what you are seeing the sharpest.] That bit of knowledge got me hooked on the 90 as my "normal" lens, with the 50 as my wide.
