Originally posted by pingflood By "on crop" I meant when used on an APS-C sensor camera; e.g. 18mm "on crop" would be in the same category as say 28mm "full frame". Hope that makes sense.
I guess it makes sense, though I was taught that 28mm means 28/1000 of a meter. Focal length is focal length regardless of the detector/film format. A 28mm lens used with APS-C is the same as a 28mm for any other size media.
For the purposes of this poll, it probably would have been more useful to skip the focal lengths and categorize the lenses according to class (ultra-wide, wide, normal, short tele, medium tele, etc.).
