BAD INFORMATIO, the OP ask about the 60D which is a crop. The Tokina is for a FF, which I have and find it performs well..

Why is that?

Indoors, I would think DOF would be an issue. I tend to use the smallest apeture I can when shooting an interior in order to get as much as possible in focus. But I am interested in your position.

Suggest that you check out www.lenstip.com. It looks like they have done an extensive review on all or most of these lenses. One aspect I am most interested in is the various distortions, which they do test for.

A 10mm lens at f4 on a crop sensor camera will get everything from 3 feet to infinity in sharp focus (as calculated using http://www.dofmaster.com/dofjs.html Wide angle lenses have great DOF capability.

My bad. I thought the 60d was full frame. The ultra wide angle canon only works on EF-s models. Sorry

All those lenses are quite good, but none of them are what you might call "low light" lenses. And you have overlooked some of the best in the category.

The Canon EF-S 10-22mm has probably the best image quality of all in the ultrawide category, even though it's been around a few years. Besides excellent image quality, it's the most flare resistant, has fast and reliable USM autofocus ("ultrasonic motor" ), and it's well built and durable.

The Canon EF-S 10-18mm is a new model and the most affordable of the bunch at about $300. It is the only one with Image Stabilization and STM focus drive (Tha's "stepper motor", which is smooth and quiet and especially good for videography... STM is not quite as fast as USM in some cases, but I doubt you'd notice the difference on an ultrawide lens like these). I haven't used this lens personally, but have heard it's got pretty good image quality. The image stabilization can help with camera shake when you need to use slow shutter speeds for low light... but no form of stabilization can help at all with subject movement.

The Tamron 10-24mm is a decent lens at a relatively low price, though it's not as affordable as the Canon 10-18mm. Until recently it offered the widest range of focal lengths in a single lens, but I found it typically a little soft at the 24mm end of the focal length range and a bit more plasticky than the other models. Even though it's pretty good, I ranked it's image quality behind most of the others. Until the Canon 10-18mm was introduced, this Tamron was usually the least expensive too.

The Sigma 10-20mm actually comes in two versions. There is a cheaper one with a variable aperture (f4 to f5.6, if memory serves). You cited the f3.5 non-variable version, which is one of the most expensive lenses in this category... and also is the largest and heaviest lens in the group. It uses an an 82mm filter, while most of the others use 77mm or smaller (82mm filters tend to be significantly more expensive). Both these lenses are pretty good. They feel well built... even better than the Canon 10-22 (which has some plastic constructions)... though it's hard to say if they are actually any more or less durable. I tried out the variable aperture version some years ago and didn't feel it's image quality was as good as the Canon.

You completely overlooked four Tokina lenses in the ultrawide category. There were the 12-24/4 and 11-16/2.8 (still available used, and maybe even new)... which not long ago were superseded by the 12-28/4 and 11-20/2.8. I have used the first two, but not the two more recent models.

I haven't used a few of the newer models, but still consider the Toki 12-24/4 the second best ultrawide zoom, right behind the Canon EF-S 10-22mm. When I compared a bunch of them years ago, the Tokina 12-24 seemed a really good value and had image quality closely rivaling the Canon, and actually feels better built (almost "L-like" ). It's just not quite as wide, "only" 12mm, but has a non-variable f4 aperture.

The Tokina 11-16mm and the new 11-20mm are the lowest light ultrawides you'll find, with their f2.8 apertures. This does make them a bit more susceptible to flare. And the newer model has gotten larger, which I haven't used personally, has 82mm filter threads. The 11-16 might be the sharpest of all the ultrawides (and is popular for astrophotography, for this reason), but it also is the most flare-prone. I know of some photographers who tried it, but couldn't live with the flare issues. Some others work around that and love the lens. Again, I haven't tried the newer one, so can't directly compare.

(Note: there actually are two versions of both the 12-24 and 11-16, the original and a "Mark II". However there is almost no noticeable difference in the Canon-mount versions... It's a bigger deal with the Nikon-mount, because the more expensive Mark II has a built-in motor that allows it to autofocus on any of the Nikon DSLRs, while the lower priced original version did not have a motor, so will not autofocus on many of the more entry-level Nikon DSLRs).

Finally, there also is a Sigma 8-16mm.... this is the widest of the ultrawide. It's a cool lens, but a bit pricier than some of the others, has stronger distortion effects (inherent to ultrawides) and has a convex front lens element so cannot be fitted with standard filters.

Another ultrawide is the Sigma 12-24mm. That actually is a full-frame capable lens and is much higher priced, with some relatively strong distortions and aberrations. It would be ultrawide on a 60D or 7DII, too... but really would be sort of a waste of money using it only on crop sensor cameras.

And there its the Samyang/Rokinon 14/2.8. It's a relatively affordable (under $300) ultrawide prime lens that also sells under a bunch of other brand names, including: Bower, ProOptic (Adorama), Vivitar (who call it a 13mm) and more. It also is full-frame capable and has some relatively strong "mustache" distortion. Most notably, it's a strictly manual lens.... manual focus and manual aperture only. That makes it a bit slower to shoot with. And it can be challenging to focus a stopped down lens in low light. Note: there are also Canon 14mm and Zeiss 15mm lenses... But they're very high-end, full-frame-capable and, I suspect, cost a lot more than you want to spend.

Have fun shopping!

Thank's Alan for your input I canceled my order for the 10=18 mm and will rent the Canon 10-22MM to see how I like it then I'll purchase one of the Two.
Thanks to everyone again.

I was commenting on the comparison between the EF-S 10 - 18 and the 10 - 22, where any difference in depth of field would be small, not that DOF doesn't matter.

I sent you a private message.

BAD INFORMATION And there its the Samyang/Rokinon 14/2.8. is for Full Frame. They do make a dedicated lens for crop. I had one very briefly. I bought it used and sold it quick as I had bought the Canon 10-22 EFs.

All other information is mostly spot on. I bought the 10-22 before I purchased the 15-85 and am amazed at 5mm difference.

Sorry but thought it needed clarification.

Double post, Sorry!

None of them are exceptionally fast lenses, but should do a good job for you. I had the Canon EF-s 10-200 and it was a fine lens. I think now that the 10-18 is out and less expensive I'd buy that one if I needed a wide angle lens again.

My answer is f/2.8 Lenses take excellent indoor photos without a flash.
Not so good with the slower f/3.5-4.5 Lenses you're looking at.

Indoors, no flash is not going to be the strong suit of the 10-22 coupled to the 60D unless it is on a tripod using slow shutter speeds and high ISO. On a 7D MKII it should be much better, keeping in mind indoor light can be many things from bright to unbearable. At a minimum suggest looking at something with a 2.8. Maybe the Tokina would better serve your needs.
Possibly cheaper to go with a flash and not worry about it?
The Canon 10-22 is pretty much a standard lens for real estate photographers on both FF and crop sensor. Combined with the 7D MKII, I would think it a winning combination.
