    For 35mm film or full-size digital imager, the choice has to be
    55mm prime. Usually an f/2 for the best compromise in speed and
    resolution.

    For those who may never have heard of a 55 or used one, the
    reason why this is an ideal focal length is it makes for a 1:1
    ratio of viewfinder to subject apparent size. One can viewfind
    with one eye and sight the field with the other and the two
    sightings are congruent. It's amazing what difference 5mm can
    make: a 50 makes everything smaller, ie., a wide angle effect.
    I have no idea why the manufacturers went to 50mm when 55mm was
    common in the early 70s, except maybe its cheaper to make a 50mm
    than a 55mm for a given maximum aperature.
