Another question regarding the efs lenses as I have one I think.
I think I have a 17-55 f2.8is lens
If I set it to 50mm will the field of view be the same as an ef-50mm lens on a 7d2? Or will it be closer to a ef28 on the 7d2?
I guess my question is really does the efs lens adjust for the smaller sensor or do it match the same field of view as an equaling sixe ef lens and there are other reasons you can't use them on ff cameras?
50mm is 50mm regardless of whether it's a prime or a zoom, HOWEVER, many zooms do not behave the same as a prime at a given focal length. By this I mean that it may say 50mm but it may, in fact, give the field of view of a shorter lens depending on your focus distance. Some lenses, have a drastically different effective focal length when focussed close. A couple of "famous" lenses showing this behavior were some models of Nikon's 70-200 and their old 70-180mm Macro.
The only reason I mention it is that you may make a comparison at some point and wonder what gives!
