So a while ago I bought a sigma 24-60 2.8, for about £150. It's never been hugely sharp, but it let me down massively at a wedding recently. I ran it through a moire based AF test and it's all over the place.
Long story short, it doesn't focus consistently across the zoom (not so much a problem) nor consistently when you are closer/further away from a subject. That's a huge problem; I can't ask everything I take pictures of to stand at exactly 3.5m and hope for the best.
Anyways, I'm looking for a replacement. With this lens and a couple of other cheapies, I can get about £200 trade in and can save a little money to go towards something else.
I've got a 7D, and I've found the 24 to be a little too zoomed for me, but I love the 2.8
Locally, one of my camera shops is selling a 17-40L for £449, and that seems like the best option to me. It's nice and wide and the L glass is always good.
I was wondering if anyone had any good suggestions? I'm not adverse to third party options but if possible I'd like to avoid Sigma.
