And yet.....
Lolz at someone obviously trying to defend there expensive purchase.
I think there must be done variation in sigma lenses...big time.
I'm sure there is but I for one have never had a bad copy.
I'd suggest trying the sigma in store and if it's sharp, ask for THAT copy!
I've bought all my Sigmas in store after trying them and always ended up with a good'un first try - just lucky, I guess! The one excption was when I tried my 12-24 but the shop couldn't meet their online price instore. I asked if it was possible to ensure that I got the copy I had tested if I ordered it online and, sure enough, it was. Oh, and my 8mm fisheye which came from here - it was described as brand new etc and since the seller lives in Scotland, it wasn't practical to test it! When it turned up, it was as described, still sealed in a plastic bag in its case in its box. AND it is a good copy. (And was about 1/2 the new price.)

I've also had a 120-400mm. Sold it for the same reason above and you guessed it, I thought it was soft where others claim it to be pin sharp.
Tom (TCR4x4) has an incredibly good copy of his 70-200 but it goes against the charts and reviews RE wide open sharpness...

sorry to drag this up again... people saying that the sigma 70-200mm is a fantastic lens are you using the older none os version or the os?

Happy to ramp up the iso on my D700 also, but since having the OS version, I havent had to as much.
TBH, my 70-200 tends to live in the cupboard at home, unless I'm pretty sure I'll need the speed. I carry a Nikon 70-300 VR instead - the VR is excellent and the extra 100mm makes all the difference on FF!
Soda Farl said:I loved my 70-300vr but from 200mm - 300mm it was pretty poor. I have the SIGMA 70-200 O.S now and when I need the extra focal length I just use it with a teleconverter. I have the 1.4 and the 2x there is a noticable drop of in performance with the 2x but the 1.4 is great and it makes the lens f/4 all the way through so still faster than the 70-300vr.
Tommy can you give a bit more light on the OS version and a 2x? I had this in mind for a next buy...Sharpness wide open/AF/vignetting?
