Sigma 17-35 mm f2.8-4.0 EX DG HSM

Review Date: Apr 20, 2005 Recommend? | Price paid: $400.00

Pros: None really
focus problems with Canon EOS Cameras

Ok I've had the lens back from Sigma. I did ask for my money back but as their warranty says - they don't warrant that the lens is fit for purpose so if you want a $400 paperweight get this lens!
It came back with an invoice saying that they had replaced the optics - well it's certainly different to what it was but it's actually worse. I won't bore you with images but it still has serious focus problems.

Any company that doesn't warrant it's goods as fit for purpose, in my view, should be given a very wide berth. Save up a bit longer and get a Canon lens - in fact even the 90 18-55 kit lens with the 20D is better than this one

Pros: Can't think of one!
Focus problems with Canon EOS 20D

First let me say that there may have been a fault with my lens but... there seem to be a lot of faulty ones out there. Basically mine was just about acceptable above f8 as the depth of field at f8 and avove meant that the focus point may just be in focus. At wider apertures the CA and distortion at the edges are far far worse than on the cheap 18-55 kit lens that comes with the camera and the lens thinks it's in focus when it's not.

It's been sent back to Sigma. I'll report back when I hear something
