This brings up some questions.
On a 35mm camera a 85-105mm lens is considered a portrait lens because
it keeps people noses smaller than a 50mm up close.
Now say a 55mm lens on a 1.6x camera (APS-C) equal 88mm. Is the 88mm
lens a portrait lens or do you get a big nose because it is really a
55mm lens?
Forget focal length; you pick the focal length to give the angle of view
you want, but it has nothing to do with perspective. It's where you put
the camera that controls the perspective. If the camera is close, the
nose looks big; you want it farther back for an ordinary portrait look.
(Skipping for the moment the fact that one sometimes wants to do
drastically unconventional things.) Which makes it very clear (to me,
at least) that it's 85-105 *35mm equivalent* lenses that are "portrait"
length. You don't use that *actual* focal length range for portraits on
a 6x7, or a 4x6, either.
