Hi all,
I stumbled over two more questions during my internet research :-).
1) The Rebel DSLRs have a crop factor of 1,6. With a full size (35 mm) sensor, a 35 mm lens would mean a 1x magnification factor, right? With the rebel a 35 mm lens would mean a 1,6x magnification factor, or? Therefore a 75 mm lens would mean a 3,something magnification factor on the rebel, right?
2) I stumbled over this lens: EF-S 17-55mm f/2.8 IS USM. Why does such a fast lens need image stabilisation?
Thanks,
Michael
