Lets say we have a fixed focal length (28mm) and it is made for APS-C. When are mounted on a DSLR with a crop factor of 1.5, does this lens gives a true 28mm focal length? or will the crop factor still have to be applied and becomes 42mm?

:think:

the difference is that it's supposed to be smaller, cheaper and you cannot use it on your full frame cameras....
