I'm really itching to buy this lens since it's a heck of a lot cheaper than the Canon 12-22mm. Anyone have any thoughts? Likes? Dislikes?

I do know that I can use this lens in most EOS bodies as I'm also thinking of getting an extra body. Maybe the D60 or the 10D. The canon only fits two bodies so that's a bit of a deterent.

Thoughts?

What do you want to use it for?

I'm getting the Sigma 105mm for macro, portrait and wide angle shots.

Started a little forum last week getting some advice and samples ...

I plan on using it for landscapes.

I don't know much about the Canon 12-22, but the Sigma 105mm has had awesome reviews and from what I have been told, should be suited to landscapes. Its a very versatile lens.

Am sure its a pukka lense, but reckon it's way to long to be too useful as a landscape lense (the Sigma 105 I mean)

Well... what about the 10-22mm (as this thread says)
:D

Its a fantastic lense, I have no complaints.

Canon doesn't make a 12-22mm :-) But, Rikki, that 10-22mm lens is as pure and free of barrel distortion as any superwide I've ever seen. This might be a real boon for you with your architecture. Check carefully to see that the Siggy matches the Canon in this regard.

Edit to add: the Sigma is also designed for 1.5/1.6 crop cameras. They say it has slight vignetting on 1.3 crops; so I'd assume it won't go full frame anyway.

I loooove my sigma 10-20mm! I can't compare it to the Canon (becasue I've never tried the canon) but I do like the fact that its an EF mount (vs EF-S). I have never had any complaint with softness or too much distortion, but if you do alot of architecture you may want to double check.

Also, check out this review, it was a big push for me to buy this lens.

Yeah... If you look at the interior shot in that review you'll see barrel distortion in the ceiling. And I trolled around on the web and found some more interiors that exhibit the same thing. For what it's worth, the Canon is clean in this regard; virtually NO barrel distortion. Not a big deal for general work, it's relatively minimal, but a problem for architecture.

Another contender in the wide wars is the Tokina AF 12-24mm f/4 AT-X Pro DX, a review is here: Tokina
Although I have the Canon 10-22, and am very impressed, if price is a consideration the Tokina might also be a consideration for these wide indispensable focal lengths.

I have the Sigma 12-24 and I really like it, but I'm considering the Sigma 10-20 as an alternative.

Yeah you're right Rob't. There seems to be a bit of barrel distortion there. And you're right in calling out that I might use this for interior shoots. Is there any software that could potentially fix BD? The extra $200 is a bit much to fork out for the 10-22mm EF-S. And I can only use it for the 20D and the Rebel XT :(

It's not just interiors, it will curve the verticals on exteriors also if they are close to the frame edge. And this lens also is only fully functional on cropped sensors. That said, you can get Richard Rosenmann's "Lens Corrector Pro" to fix the barrel distortion. I used it for my coolpix 5700, works like a charm.

I got the sigma 10-20mm from amazon after reading most of the reviews available for it (not too many out there). But anyways I tested it for a day and have to say i was really dissappointed with the optics. Dont know if i just got a bad version or what, so i sent it back to amazon and Im getting the tokina 12-24mm instead which popphoto has deemed to be sharp and optically very good at 100%.

A lot of the shots up close looked similar in quality to the kit lens. I know the kit lens has gotten bashed a lot, but its not that bad. However considering the kit lens is cheap and the sigma costs $500 I was expecting something a lot better. The last lens I got which was the tamrom 28-75 was razor sharp so maybe my standards a set a bit higher but i wasnt impressed at all with the 10-20's optics. That being said it was well built, not to heavy and just the right size, and came with a nice lens hood. The zoom ring is sturdy and turns nicely. I liked everything about the lens except the optics and unfortunately that is the most important thing because I need shots that look good at 100% and this is where the lens fell short.

hmmm... seems like more and more I'm starting lean towards the more expensive Canon
10/13/2005 03:33:26 PM · #17
Rikki, if you are patient, there are some deals on eBay for the Canon. I have been watching for a few weeks now. Unfortunately, I did jump on a brand new one that went for $580. I have been watching and hoping for another deal. Most are going for low-mid $600's, so you can get something a little bit off wholesale.
