I have recently norrowed my search to the sigma 18-200 because of the range it covers. What does anyone thinks about this choice? Have heard different opinions about it : some say it's a good choice some others say that it's slow at long end, not sharp or has not any decent AF neither...
Another possible choice would be the Sigma 18-125. Basically I'm looking a good lense to keep on my second body which basically covers many shooting needs...
What are your opinions ? Any other possible candidate ? Thanks to all for input.

hi, well I've tried the sigma 18-200mm on my D200 before and i found it very soft and slow above 100mm, so not really good for moving subjects, i think is ok for ground stuff and static displays. Thanks. Yuan Le
Back in China now. Camera used: Nikon D70 D50 D200 D40 FUJI S3 PRO Canon 400D. Now with Nikon D7000.
Might be due to the "enormous" range this lens has, it starts at 18mm which is a quite good wideangle and ends at 200mm which is quite long, more than a 10x zoom.... I wouldn't buy it, get one with a smaller range, maybe 4x or 5x at most.

I'd agree with that - I bought that lens a couple of months ago and I'm using it with a 400D. On the wide end it is sharp, but I find it soft on the long end, even in bright light and using a tripod. I previously used an Olympus C765 compactish camera and I sometimes find it's sharper still.
The Sigma lens doesn't seem to like filters very much, they affect AF it seems.
