you shouldve made a comparison on a 50 mm vs 100mmLet me see if I can give you a sense of it here:
Forgive these photos. They're nothing exciting but maybe it'll give you a sense of the focal distance differences.
I'm standing 6.25m from this wall.
This is at 14mm (24mm equivalent):
This is at 50mm (100mm equivalent):
100mm is fairly long for most personal uses. For something like shooting stage performances it might be quite appropriate though.
One thing i Kinda like on the crop factor is lesser distortion or no vignette.
and of course it sucks when it comes to wide lenses.. we have a few wide lense selection
