Im trying to save up for some new lens on my canon t3i. I could eventually save for an L series lens but there are alot of other choices. I am mostly interested in night time, architectural, landscape, and astrophotography so I need an aperature below 3 if possible. I have been looking at this lens -
Tokina - 11-16mm f/2.8 AT-X116 Pro DX Digital Zoom Lens for Canon but I really need some suggestions. If a cheaper lens creates issues that can be fixed by photoshop its ok but I really need some advice here. Budget currently is sub 700 range.
