Nature/outdoor photographer using a APS-C (1.6) body.
Option 1: EF-S 10-22 and a EF-24-70 so I can shoot the wider views, or
Option 2: EF-S 17-55 (Is this wide enough)
I would rather not own a 10-22 and a 17-55 (too much overlapping focal length and I dislike paying twice for the same thing). So, my question is: Will I really need a 10-22 if I have the 17-55 or should I just go with a 10-22 and 24-70 combo?
IS is really irrelevant as I shoot most often from a tripod.
Thanks and I am looking forward to hearing the reasoning.
