Hello, I am a newbie in DSLR, and I would like to ask for some help regarding the relationship between a cropped body camera and lenses.
Take for example, a cropped body camera like Canon 550D, and a EF-S18-135mm.
My questions are:
1. The EF-S18-135mm lens is actually not a 18-135mm lens but made to function like a 18-135mm lens on a ff camera, so that a cropped body like Canon 550D can function like a ff?
2. If a lens like EF-28-135mm is used with a Canon 550D, the lens will fucntion almost like a 44.8-216mm lens (x 1.6 times)?
