Wherever is cheapest... Adorama and B&H are very reputable online sellers, sometimes there are good deals on Amazon.com, too.
Check canonpricewatch.com.
I am kicking around the idea of an ultrawide lens for my 7D. Does anyone have experience with the Sigma 8-16? Right now I am leaning toward picking up a Canon 10-22 before the rebates end, if I do anything at all, but I am still a little tempted by the extra 2 mm/12 degrees from the Sigma. Similar to Dr. Croubie and kolorange, I have also been looking at the Sigma 10-20 f/3.5 and f4-5.6 and the Tokina. I am probably not going to wait for the new Tokina as I am used a trip I just booked in March as motivation for the lens. I would be using the lens mostly for landscapes.
Thanks,

i have a small doubt. Why do everyone prefer big aperture in wide angle lens? i know, that big apertures give more light. but then in that case, we mostly click the landscapes at 8 or higher value aperture for more span in focus.
if we use bigger aperture in wide lens, we have very less span in focus. so how does a big aperture in wide lens help?
i am planning for a t3i and interested in a wide lens. i would like to know, if i can replace the kit lens with a wide lens? as i already have a kit lens in my family which i can share. so i dont want to repeat the kit lens and get another good option.
please suggest.
A wide aperture helps mainly for handholding in dim light. Especially with the short focal length, DoF can be pretty deep even with a wide aperture. Here's an example of a handheld shot at f/2.8 where I was already at ISO 3200 (which is as high as I like to go):Originally Posted by DJ 86

in this image, at 2.8F, why the focus is not very tight?? i can see the background is not totally out of focus. and landscapes are clicked at smaller apertures for large span in focus, then how do we utilise big aperture?
can i see some more examples where wide lenses are used with big apertures?

35mm, F/1.8, ISO 3200, 1/50, an example of fighting to get enough speed to get a shot in almost total darkness. I had no lighting behind me and no flash used.

DJ, this shot focused on a very near-field object. Given the focal length the statue may have only been a foot from the lens. The fact that the building is recognizable as anything other than a blur is a result of using such a short focal length lens.
If someone were to frame the same scene of the statue with a telephoto at the same f/# the magnified blur of the building would have been unrecognizable as such. Each style of photo has its appeal. That's the artistic portion of photography.
Moving to SLR's you're leaving the world of point-and-clicks with micro-sized sensors. SLRs are far more capable but also more complicated and difficult to drive well. The SLR community does not speak of magnification powers per se. Instead everything is discussed in terms of the framing of the image relative to a 35mm negative. Any given focal length will capture light from a given arc in front of the lens. That's what ends up on the sensor. After taking that into account then the f/# and focal length and object/background will dictate what's in or out of focus.
If you're truly only interested in shooting landscapes that cover a wide angle with a narrow aperture then pretty much any lens with f < 35 mm will do. Obviously the more expensive the lens the better the image quality. However, most of us are not so single-minded in out photography desires. So having a mixture of focal lengths and the option for wide apertures allows flexibility.

One thing I found is just because your lens will shoot at F/1.4 it doesn’t mean you should be shooting at F/1.4. Close range even with a wide lens it can be hard to hit the exact sweet spot (thinking back about one of our past members who loved his 35mm F/1.4 at just F/1.4). Although it made for interesting cork pictures (arguably).
You want the wide aperture for low light, like indoor settings where you have no flash. You fight a battle to keep your ISO low, your shutter speed fast enough to avoid camera shake and your F# to give you the minimum setting you need so you can get a sharp un shaken picture.
Another use is to blur the surrounding background. Even in good light you use a low F# to isolate a subject in a crowd with a narrow depth of field. While a wide lens isn’t usually known for its bokeh, it can produce at a wide enough aperture.
While Canon’s 35mm and 24mm F/1.4’s can produce very nice pictures. Wide open the IQ falls off quite a bit. Around F/2.8 there IQ is quite acceptable.
If you are shooting landscapes off a tripod a wide aperture lens is less of a requirement.
