So, there are things I like about this lens. It's made for an aps-c body, such as my t2i. It's compact, even with the barrel extended. The front lens element doesnt rotate (unlike the Canon 55-250, which has more of a focal length range, but a couple downsides - such as the barrel, and the rotating front, that I didnt). And I hope that this doesnt come off as smug, because I promise that isnt the intention. Have I found the best in what I am looking for within that price range? Am I overlooking another lens in a similar range? I was able to get this for $150 off of eBay. What I am asking is that as much as I like it, it still feels fragile in the hand (although it may not be. But I'm not about to drop it to test) As I said, I have no interest in the Canon lens mentioned above. I LOVE the old Nikkors. But a lot of those lenses don't have the auto focus. The Sigma has AF and even image stabilization. Is there another lens that has most of these features that I overlooked? If not, I will learn to get over any downsides this lens has. If so, I am willing to invest in new glass, under $300 preferably. Older glass is fine, but autofocus is a bonus.
