Ok, here is my gear being re-tooled, please help me by choosing a lens to fill the gap. (If two apply, please post your comments and why).
Background info: I do a lot of press photography, so I need a nice walkaround lens for hauling at all times outside, for any and all assignments, and yet I do a fair amount of indoor/lower light photography (City Halls, News Conferences, hallways, dusk - Comparable to Wedding photography conditions, but I do not do Weddings). So use this info, to decide -if this were you- whether you would go with IS or a wider aperture value.
So Here we go:
Canon MkIIN
Canon 30D
Sigma 10-20
[Choose Lens/lenses Here]
