I'm using a T3i/600D currently with the intention of developing my skills while building a lens collection and switching to a full frame (5D-MKIII) in a year or so.
I couldn't wait to save up for a Canon 300mm so I purchased the Tamron 70-300 VC.
Right now, I'm looking for a Canon wide-angle lens to use on my T3i and the MKIII later on. While not knowing much about wide-angle lenses, I found myself looking at the "Canon EF 16-35mm f/2.8L II"
Correct me if I'm wrong but, since I'm using a crop-sensor camera the true lengths would be (25.6mm-56mm).. Is that correct? Now, would this still function as a "wide-angle" lens on a crop sensor?
Another question is, I already have the 18-55mm kit lense.. how is that range any different than the same range the wide-angle lens going to produce?
