Sigma 20mm f/1.8 EX DG Aspherical RF

Review Date: Nov 16, 2006 Recommend? no | Price paid: Not Indicated | Rating: 1 

Pros: Good price, wide aperture, close focusing.
My copy was an unusable dud.

Now I'm first to admit that the copy I received was a dud and the store I bought it from was happy to order another one in, but it took 2 months to get the first and it was going to take at least another month to get the second. So I went with the Canon 20mm f2.8, which took 3 days to arrive and works wonderfully.

So I'll review the lens I received.

One of the first shots I took with this, cropped to 25% and minimal USM to compensate. Notice the top right hand corner.

Here's the 100% crop, no sharpening.

For the brief time that I used the lens I found it was built nicely, I really didn't seem an problem with the focus clutch wheel. It would have been a good feature if you didn't have to hit the AF/MF switch as well (of course now I have my first USM lens with full time MF and realise that the sigma method was a joke). I really liked the magnification factor as you could do some fun things with it and the f1.8 would surely have been useful, I'm worried I'll miss it using the Canon 20mm.

I was really concerned with ordering third party glass and I guess my concerns were justified. As you can see the lens was unusable.
