I have been trying to decide on a wide angle lens for spring break. I will be travelling to an area with quite a few beaches.
I would like to keep my budget under $400, and I have narrowed my choices down to two lenses:
-Sigma 10-20mm f/4.0-5.6 HSM DC AF
-Sigma 17-70mm f/2.8-4 DC Macro OS HSM (old version)
I originally decided on the 17-70, but I read something about how zoom lenses perform best in their middle range, and I would most likely be shooting at the 17-25 range of the 17-70. Would this be a problem?
What are the pros of each lens? For my budget, is there a better option? (I could spend up to 500 if the lens would be that much better). I am not against buying used.
I shoot with a Canon 50D, so I have a cropped frame.
