I saw Roger's answer, but I am wondering if this calculation factor of
1.6 is just for the equivalent focal length for digital, because of the
different 'film' plane size. I am guessing it is, since AFAIK the 18-55
mm lens on a digital is roughly equivalent to the standard 28-80 mm
lens that would come with a film-based SLR?
TIA,
Richard
