Sigma 20mm f/1.8 EX Aspherical DG DF RF for Canon

08/06/2005 11:59:05 AM · #1

Well, I scrapped my original fisheye prime idea, and I'm now looking at super-wide zooms. Both Tamron and Sigma have recently come out with new products. Tamron has the SP AF11-18MM F/4.5-5.6 Di II LD Aspherical (IF) (not yet added to DPC Lens list) and Sigma has the 10-20mm F4-5.6 EX DC HSM. I've been able to find a pretty good review of the Tamron and photo.net and luminous landscape, both of which showed it as a pretty good lens. There doesnt seem to be anything at all written about the Sigma lens.

Does anybody know if, in general, Tamron is better quality and sigma or vice-versa? The Tamron is $100 more, but the Sigma has some added features like FTM focusing. Anybody here have any idea which one might be the better choice?

As usual, DP Review Canon SLR lens forum has sprinkles of samples that people that just got the Sigma 10-22 have taken. I don't remember anything on a review site though.
Should do a search over there.

Tokina also makes a 12-24mm which is supposed to be very good and at a nice price.

No mention of the Canon 10-22 f/3.5? That's an exceptionally fine WA zoom, completely free of barrel distortion, optically pure, at around $700.00... The Tamron is "listing" at 900+, I don't see how it can compete. The Sigma, at around $500.00, is attractively priced but I haven't seen any comparos.

The tamron is only about $569 at B&H, and they also have a Student Purchasing Program going on right now (applies I THINK to any student/faculty at accredited universities (although may just be photography schools)) where you can get it for $475. The lowest listing I found on the Sigma was about $469 (B&H again, although out of stock)

Sigma keeps saying "coming soon" for over six months now and B&H for almost as long, but they still haven't released it. I got tired of waiting and went for the Tokina 12-24 instead.

Just noticed that the sigma has become 'In Stock' at B&H for the Canon mount.

Which brings up another question I had, since it's now feasible that I might be able to by the Sigma before I go abroad.

In the specs, the Angle of View on the Sigma (10-20mm) is 102.4 - 63.8 degrees. On the Tamron (11-18mm) its 103-75 degrees. Does anybody know why, if the tamron is 11mm and the sigma is 10mm at widest the tamron has a wider maximum angle of view?

Edit: Not that its a big deal, just seemed strange to me.

Pure guess: because the Tamron is 'fishier'?
