The 10-20/22mm range lenses do give some great results, as mentioned in an earlier post I have the Sigma 10-20mm which for me is a better built lens than the Canon (I've used both) although the Canon is slightly brighter and has the extra 2mm. All of the super wide zooms have their advantages and disadvantages so check out the reviews as shown below.

Sigma 10-20mm http://www.photozone.de/8Reviews/len..._456/index.htm

Sigma 12-24mm http://www.photozone.de/8Reviews/len...4556/index.htm

Canon 10-22mm http://www.photozone.de/8Reviews/len...3545/index.htm

Tokina 12-24mm http://www.photozone.de/8Reviews/len...24_4/index.htm

There is also a Tamron but it does not do as well as the above so would not add it to the list.

Hope that helps,

Mark

Mark: Thanks so much for going to the trouble of assembling these links--looks like I've got some reading [and comparison shopping :idea: ] to do.

Cheers,

You're welcome.... only took a moment as I always check out that site when considering a new lens...... however I have to behave now as I have enough (hmmm can you ever have enough LOL) lenses to cover the shooting I do. Actually I would like to change my Sigma 70-200 f2.8 to the Canon IS one for shooting weddings but that is not essential. Basically there will always be something on the wish list for any keen shooter, however my advice is to master then lenses that you have to get the most from them.

You just can't get too wide. I use the 12.24 Tokina. Had excellant reviews and fixed F4 aperture.

Have read a lot of reviews and I'm pretty settled on either the Sigma 10-20 or the Canon 10-22:

Sigma 10-20mm http://www.photozone.de/8Reviews/len..._456/index.htm

Canon 10-22mm http://www.photozone.de/8Reviews/lenses/canon_1022_3545/index.htm


The Canon is obviously a pricier item and as Mark pointed out, they all seem to have their drawbacks in that range. But I seem to be reading pretty consistently that the Sigma is neither asd bright or sharp as the Canon.

Is there a significant difference?

In reading I saw a lot of good things about this Tokina, but if I'm getting something in this range I think I 'd want the 2 mm on the wide end:

Tokina 12-24mm http://www.photozone.de/8Reviews/len...24_4/index.htm

It's a significantly better buy than the comparable Sigma, but again, with such a limited range, I'd think the 2 mm on the wide would be fairly significant. Is this assumption correct?

Might end up getting something before next Thursday, when I leave for Turkey for two weeks. That'll be my first chance to really spend some time shooting.

I agree on the brighter part if a 1/3 of a stop is that significant (i.e. f/3.5 vs f/4)
Also when one uses theses superwides stop down is the way to go for landscapes!


-> However the measured results on the links you posted shows the opposite:

Canon EF-S 10-22
@ 10mm f/3.5 f/5.6 f/8 f/11
Center 1818 2003 1891 1771
Border 1405 1527 1577 1537
Extreme 1510 1577 1619 1563

Sigma 10-22 HSM EX

@ 10mm f/4 f/5.6 f/8 f/11
Center 2018 2089 2040 1862
Border 1635 1714 1736 1650
Extreme 1534 1702 1777 1670

The Sigma is quite sharper @ all apertures (and focal lenghts - just check the results)!!!

This Sigma also has HSM vs the Tokina without and IMO the difference between 10mm and 12mm @ the wide is quite significant...

NHL:

Thanks for clarifying. I'm a bit embarrassed to admit that I'm not particularly knowledgeable when it comes to interpreting some of these results. :O

The Sigma seems to be the way to go. Thanks.
