Reply to Canon EF-S 10-22mm f/3.5-4.5 USM alternative

Crop factor does apply on the EF-S. That is why EF-S lenses are often made in zoom ranges 1.6 times less than their full frame counterpart.



For example:

EF-S 60mm macro, vs EF100mm macro (60 x 1.6 = 96mm)

EF-S 10-22mm vs EF16-35 (10 x 1.6 = 16, 22X1.6=35.2mm).
