I still have some tamron lenses for my canons but i'm replacing them with Canon glass as I can afford it. I have yet to fins a lens from any aftermarket mfg that is good as the Canon glass in any focal length. I'm sure you can find tamron or sigma lenses in te f 2.8 range that is better than the Canon kit lens in the same focal length but if you compare low cost with low cost or premium with premium, in canon mounts, canon will always win. If I really needed a particular lens and just could not affort the Canon L then if I could save enough and quality wasn't the prime concern, then I might consider a premium tamron or sigma but if i then found that i did really need a lens in that focal length, I would start saving for the canon L. When I got it I would sell the off brand on e-bay, knowing i would get about 50% of what I paid.

I purchased a t3i recently. I was told at a camera store that with my camera, that the numbers in a wide angle lens had to be calculated up to get the true function...ie...with the T3i, a 20 mm lens is actually 30 mm. A 15mm would be 22, a 10 would be 15 and so on.

Until recently i would have agreed with you. However i found that the Canon 17-40 f4L lens to be optically inferior to the Sigma 15-30! I couldn't believe the test results and so repeated them - but found the center sharpness and contrast of the Sigma to be slightly better. It's a bit wider too. I sold my 17-40 in a heart beat and was $$$ better off!

Ken Rockwell ( kenrockwell.com )Swears by the Tokina 11-16mm - says it is sharper than the Nikon 12-24 ! See his review.

Good thoughts.... The cannon is a couple hundred higher. Strangely enough... the used ones didn't seem to be appreciably cheaper on ebay...
Canon does sell "refurbished" lenses on their site. I bought one recently and it has been a great. It came with a 90 day warranty, too.

I purhased the Tamron 10-24 lens prior to a vacation that included Monument Valley, Bryce Canyon, and Grand Canyon. It supplements my Nikon 28-300 Zoom. Between the two of them I've got things pretty well covered. I've been very happy with my results at about half the price of the Nikon Lens. It also provides a wide range of wide-angle shots which really came in handy in landscape situations.

Your camera, like most or ours, has a 1.6x crop factor. It has a smaller sensor than the full frame cameras (full frame meaning that the sensor is approximately the same size as a 35mm film negative). Full frames are more expensive, that's why most of us have the 1.6x crop sensor. Just multiply the lens number by 1.6. So actually, at 20mm, the lens is more like 32mm.

I am joining the club that loves the 10-20 Sigma as it has been a great lens.
The 3.5 8mm Fisheye lens is sold under a vareity of Names, Rikonin, Bower, Vivatar, etc. Bower is listed for $250 on B&H.

Just read a review by someone who bought the Tamron and "thought" they were happy with it. There was a problem within a week with the contacts. Sent it to Tamron for repair. Could not wait, as his job dictated a camera. Bought the Canon, was totally blown away by the difference in sharpness. He thought the Tamron was sharp until compared side by side with the Canon.

About a 7-15 mm would give an effective FL of 10-22.

Thanks for the info (1.6 crop factor). I am very happy with the camera, have a Tamron 90 2.4 macro and a canon 50 1.4, thinking about getting a zoom lens but dont want to spend a ton. I am thinking that a good all-around zoom lens would be best. Any help here would be appreciated.

Wow !! And it wouldn't be too "fisheyee" ?
Actually a fish eye and an ultrawide angle are two different beasts. An ultrawide is optically collected so that straight lines in the frame will look straight on the photo, while the fisheye intentionally makes straight lines look curved. Canon for example makes a 15 mm fisheye, and a 14 mm wide angle that is optically corrected for straight lines.
