I'm looking to buy a wide angle lens for my EOS400D and the most obvious choices are the Canon EFS 10-22mm f/3.5-4.5 USM and the Sigma 10-20mm f4-5.6 EX DC HSM.

The Canon lens is typically about 150UKP/300USD more expensive than the Sigma and I was wondering if anyone has experience of either of these lenses as to whether the Canon lens is worth paying the extra. I'm not too concerned that Sigma finishes at 20mm vs 22mm for the Canon, but more interested in the difference between f3.5 and f4.

Thanks in advance for any advice.

ok i really wanna throw in two more options here.

Sigma 12-24(This is a full frame lens) and honestly at 12mm this lens has no vignetting even on my 5D. This on a 400d will be around 19mm. So no problems with vignetting for sure. This is my favorite lens. There are some who say they got a bad copy. But i bought it new and the copy was spot on.

The second more feasible option for u is the Tokina 12-24 F4. This lens is specific to the cropped sensor.

This is the terrific lens at constant F4. Great for low light fotography too.

I would pick 12-24 over the 10-20 options of simga and canon. Just a thought.

Hmm, I was fairly happy with my Sigma 12-24 on the 20D, and I did pick it after comparing it to the Canon 10-22 at the store.

Once I got the 5D I only used it a couple of times before I sold it. With the FF sensor I found it vignetted a fair amount, but I actually don't mind that. But the main problem was that the "plane" of focus wasn't a plane at all; it was all over the shop and displayed OOF areas in 3 places across the frame, even stopped down to f14 or f16. [Most of the frame was moderately sharp, but not at all in the same league as the 24-105L.] Even DXO optics could not sort it out, though it did help.

Frankly it was so horrible I was glad to get something back as a part-exchange when I bought the 50L.

Tests of the new 16-35 MkII L aren't terribly promising either. Just about the best option from Canon is the 17-40L at f8/14.

If I want to go wider I will just stich from the 24-105, or fork out the cash for the new Nikon 14-24 and the exceedingly expensive EOS-G adapter. Or maybe even a Leica R with adapter. No cheap options alas.

In fact for the price of the Nikon 14-24 + adapter I reckon one of these would be a better idea - matched up with my 50L at f8/11, or perhaps with the 24-105 set at 35mm. Or if you have the cash to burn and want a massive print then stich together some shots from the 85L.

Thanks for the comments so far.

I'm always open for other options such as the Tokina. I know that Tamron do a 11mm lens too. At the moment, the Canon is the frontrunner in my mind, but I am still working on justifying the expense to myself.

I'm new to the SLR thing and not about to upgrade my camera hopefully for a long time so I'm not too bothered whether it will work with a FF sensor or not.

Both lenses are very capable, both have good sharpness, but my overall conslusion is that Canon produces more vivid colours and is way above Sigma regarding flare resistance, which can be very problematic for ultrawide lens, since you can always expect to catch some reflection or light source with that angle.

I do not recommend to go for 12mm-something, if you do not plan to go for full frame - and why should you, since you have such a good UW option as Canon EF-S 10-22.

Another thing, Canon is one half f-stop faster through the range. I think it is worth extra money.

I only have the Canon 10-22, so I can't compare, but I do love that lens. Whichever one you get, this super wide perspective is awesome and everyone should have one of these lenses. My Avatar on the left was taken with the 10-22...

Matt,

I owned the Sigma and had lots of problems. I opened a forum and discussed it, see here:

http://forums.steves-digicams.com/fo...=65&page=1

The worst nightmare came true when the dealer refused to exchange it or take it back and blamed it on a "misaligned sensor" in my 350D. Imagine the discussions with Canon or Sigma if I would really have tried to find out wheter it's a fault of my camera or of the lens. Horrible.

Finally, I've bought the much more expensive Canon and I'm really happy with it. Image quality is excellent and it even survived a drop on concrete ground without any damage.

My conclusion after extensive research and discussion in the forum: Sigma has wider tolerances within their quality assurance processes and if you're unlucky then you get a really crappy lens (like it happened to me) andthen you can only pray thatyou've bought this lens at a good dealer and not some cheapo online shop.
