Not sure what you mean by "short throw". With a projector, it means a
short focal length projection lens, so that a full size image can be
projected in a short room, i.e. the light is thrown a short distance.
125mm is certainly not a short fl for 35mm. Yes, I was a movie
projectionist during college. Long or short throw could also be used to
refer to the length of the theater.
Another possible meaning is a lens that goes from infinity to closest
focus in a short rotation of the focus ring. I can't imagine that two
full turns from infinity to 1:1 would be short throw. The Kiron 105/2.8
does it in about 1 3/4 turns and I don't feel that is short either.
In terms of distance from camera to subject or from front of the lens to
subject, 125mm is rather longer than usual for 35mm, a distinct
advantage for shooting critters, and a disadvantage with many copy
stands. not in any way "short".
Not sure what else it might mean.
