I'm just undecided on which to nab, as I like backing out to 18mm, since it's an EF-S lens and is 18mm. I'm ok at 24mm~35mm. I really don't want to push past that, since I'm using it to test what kind of distance I will have and how wide it will be.
I think I like 24~28mm.
But I also think I would like something shorter.
Options seem kind of limited in terms of a shorter, fast prime lens. I may end up with a zoom after all. I guess I'll have to see just how sharp the glass is on a few of these short zooms.
fast zoom then, sigma 1.8 or if thats too steep / heavy, there are some good 2.8 alternatives.
