Although I own an A-1, I rarely use it for the reasons stated. It was the beginning of the reassignment of dials to other purposes, which ended in the madness of the modern DSLR. Why, for instance, allocate the choice of aperture to a little wheel, when there's a perfectly positioned, large and indexed dial around the lens. Because they could, is the real answer. There's pretty much nothing the A-1 does better than other cameras, and plenty it turns into a fussy, ergonomic mess.
