bladephotog:Actually Canon has three crop factors - Full Frame - 5D and 1Ds MK II
1.3x - 1D MK IIn and ID MK II
1.6 - All others
And don't forget that Nikon's D2x has two crop factors - 1.5 and 2x in the high speed cropped image mode.
It sure was simpler when a 20mm was a 20mm in conversation. Lord, I sound old.![]()
Yes, you're right Andy. I didn't want to complicate matters too much.
