I've read the FAQs above, as well as the Top 10 Newbie Lenses post, and I've narrowed down my selection to a couple choices.
I've been shooting only with the nifty fifty, but I would like a "walkaround" lens. Most of my shooting is done outdoors. I am not a professional by any stretch, nor do I have professional aspirations. Accordingly, I've set my price range at $300 or so for this new lens. I don't have a problem buying used.
Based on what I've seen, there are two choices for me here:
1) Canon EF 28-135mm f/3.5-5.6 IS USM
2) Sigma 17-70mm f2.8-4.5 DC Macro
slightly at the higher end of the spectrum is the Tamron 28-70mm, pricewise.
Given my budget, which of the above should I grab? Any others that I should look at for the same price?
