Unfortunately and very frustratingly I have great problems with the new
Sigma 18-125 DC f3.5-5.6 for Canon (20D). (That's the only lens I could
afford when I finally got enough money to buy the digital stuff.)
Optically - for a zoom of this type - it's not bad at all.
However it is consistently inconsistently malfocusing. Typically it will
focus at a point closer than the aimed focus point. But in between it will
focus all over the place except for where it's supposed to focus at.
Being observant and working it hard I manage to get good shots, but it's a
pain to use it.
I might add that I shoot a lot of moving objects why manual focus is not
always an option.
It's still on warranty and I will get it replaced. The only reason I haven't
yet done it is because there have been so many shoots that I havent had the
time to wait for the replacement yet.
Think I will get it replaced next week, though.
What do you guys think - can I trust a Sigma EX 70-200 f.2.8 APO HSM DG will
do a good job, or will it let me down like the 18-125?

I have the Sigma 50mm Macro EX and couldn't be more pleased with it. Sure
I would prefer the equivalent Pentax but I'm happy to have paid 1/3 the
price. Sigma has had poor, lower quality, non compatible lenses in the
past but do any of the newer Sigmas still have these problems? Most
reviews I have seen of the EX and DG seem to report at least good results.
So has anyone had poor results with a late model Sigma lens?
