So I'm starting to consider my next lens, with an intent to try to buy it this summer. I can't afford more than $1000, and more like $700 would be better. Obviously, that means I'm not getting an L, much as I'd like to, but I'd still like a good USM drive if possible, and I'm not interested in anything that's not stabilized -- my hands just aren't steady enough.
In an ideal world, I'd like something on the order of 18-125 or so. The Sigma 18-125 OS HSM looked pretty good, but the reviews I've seen haven't been encouraging, particularly about its AF speed. My intent is to eventually pair it with a single longer lens (Sigma 14-400 or 150-500) or, my preference, a 70-200/2.8 with a 1.4x converter. I mostly don't have space or weight available to carry more than a shorter zoom, a longer zoom, and one more prime (the 50/1.8 right now -- it's fun, it's cheap, it's pretty good. What more do I want?), so I'm willing to accept slightly lower quality images in order to manage it.
Also, I'm currently using a 20D, with the intention of moving up to 7D in a year or so, unless there's something better by then. (Or even if there is... if there is, the 7 might be cheaper!)
So, does anyone have any recommendations? Should I give up on this search, and accept something like the 17-85? (That being another option... 17-85, 70-200, 2x TC would fit my range requirements, but require more lens-swapping.)
Thanks in advance!
