Canon 11-22mm IS STM
EOS EF-M (2013-)
Canon EF-M 11-22mm f/4-5.6 IS STM (fits EOS-M cameras only, 55mm filters, 7.6 oz./215 g, 0.5'/0.15 m close focus, about $399). I got mine at Adorama; I'd just as well get it at B&H, at Crutchfield or at Amazon.

The Canon EF-M 11-22 IS STM is a very high performance ultrawide zoom for Canon's EOS-M system.
It's near optically perfect as used on the EOS-M system. It also has remarkable macro abilities, focussing continuously from infinity to within 2" (5cm) in front of the lens.
It's a compact little lens that retracts to become about a half inch (15mm) shorter when carried.
It has plastic innards and a metal outer shell.
It has an electronic manual focus ring, that if activated in the menu system, can allow manual focus. Note that with a camera system that's usually held at arm's length I can't see how you'd ever want to use this mode; nothing is ever that far out of focus with a lens this wide.
As an EF-M lens, it only works on Canon's EOS-M series of cameras.
It cannot be used on anything else.

The Canon 11-22mm is an ultrasharp little lens that weighs next to nothing. Bravo!
Autofocus is fast and accurate, no worries here.
You set manual focus in the camera's menu system somewhere, which I never found.
It focuses by wire, and since autofocus is so great, I don't know why I'd use manual focus for anything other than to keep the focus locked for some reason.
Bokeh, the quality of out-of-focus areas as opposed to the degree of defocus, is neutral, but it doesn't matter since its nearly impossible to get anything out of focus with a lens as slow and as wide as this.
Here are samples shot wide open from headshot distance. Click either for the camera-original file to explore on your computer (portable devices rarely can display the full resolution of these files):
While you're here, notice how the spider webs are exceptionally sharp are in the center where they are in focus. The sides are out of focus; this isn't shot straight-on.
The Canon 11-22 has moderately strong barrel distortion at 11mm and 12mm, but no visible distortion from 14mm through 22mm
These values in Photoshop's Lens Distortion tool will completely remove the distortion. These aren't facts or specifications, they are the results of my research that requires hours of photography and calculations on the resulting data.

Most of the lens is its zoom ring, which works perfectly. It's geared just right and it's smooth and easy to use.
The focus ring turns well, but it only does something if you set your camera just right. I never bothered with it.
If you want to make the lens a little shorter, push the release button forwards and rotate the zoom ring to the dot. As you do this you'll see the lens get a little wider than 11mm, but the EOS M3 won't shoot since it knows you have the lens retracted and tells you so.
This is much better than LEICA's collapsible lenses, which ever since the 1920s have allowed you to shoot with the lens retracted without any warning — and with but one exception, none of LEICA's cameras have let you see that the pictures were worthless until you developed the film or played back the files.
Falloff is completely invisible as shot on the EOS M cameras, which correct this automatically by default.
Even at the worst case at 11mm wide-open at f/4, it's invisible in photos and not a problem even in the extreme case of exaggerating it by shooting a gray field and showing it on a gray background:
There's no need for thin filters. Even two stacked normal filters work with no vignetting as wide as 12mm.
Go ahead and use your standard rotating grad filters.
Don't use polarizers on ultrawide lenses; nature looks funny through them. This is the case for all ultrawides.
There are no color fringes as shot on EOS M cameras, which by default correct for any that may be there.
Macro gets very close: 2" (5cm) from the front of the lens:

Crop from above at 100%. If this is about 6" (15cm) on your screen, printing the complete image at this same high magnification would result in a 40 x 60" (100 x 150 cm) print!

This is super-sharp, and it's wide-open at f/5.6!

Image sharpness depends more on you than your lens, and lens sharpness doesn't mean much to good photographers. It's the least skilled hobbyists who waste the most time blaming fuzzy pictures on their lenses, while real shooters know that few photos ever use all the sharpness of which their lenses are capable due to subject motion and the fact that real subjects are rarely perfectly flat.
This Canon 11-22mm is super sharp. It's so sharp that diffraction is already dulling image by f/8; f/5.6 is usually the sharpest aperture if you don't need depth of field. It's sharp out to the edges wide-open. Bingo!
Canon's MTF curves confirm spectacular performance, and are unusual because they show wide-open performance is slightly better than at f/8. This is a relative first in the 30 years that Canon's been publishing MTF curves.

With curved diaphragm blades, the Canon 11-22 makes dull sunstars, if any.
This is the best I can get. See also the Sample Image at the top.
Image Stabilization (IS) isn't critical for ultrawide lenses, but its nice to have.
At 11mm, I always get tripod-equivalent sharpness with 24MP files viewed at 100% at 1/15 hand-held.
90% of my shots at 1/8 are perfect.
70% are perfect at 1/4.
50% are perfect at 1/2 second hand-held.
Even at 1 full second, about 15% of my shots are perfect at 1 full second exposure hand-held.
Of course no one displays images at 100%, so therefore I can hand hold this lens at much slower speeds and get great results for normal uses.
Here's the weird part: unlike telephoto lenses, where IS is always a good thing and usually completely fixes any camera shake, things get weird with ultrawides due to crazy perspective distortions at the sides. No matter how well IS corrects the center, it can't correct the sides independently of the center, so depending on how you move the lens in 3D space during the exposure and what and where you have on the sides, don't expect IS to correct the sides of the image as well as it eliminates blur in the center.
While this lens is ultrasharp in the corners wide-open, my shots made hand-held at 1 second that are sharp in the center still have motion blur in the corners. I doubt any of this would be significant at normal print sizes, but I can see it at 100% with 24MP images. The sides are softer due to IS' inability to correct camera motion at the corners as well as it does the center.
There are no other ultrawide EF-M lenses. Done.
The 10-22mm is the most expensive; it's also oldest and optically poorest. Forget it.
The 10-18mm is a superb lens, and less expensive. It's clunkier to use the 10-18mm with an adapter than to use this 11-22mm, but what you save buying the 10-18mm and apply towards the adapter might make sense if you plan to get the adapter anyway.
This 11-22mm has a metal mount and outsides, while the 10-18mm is all plastic. Both are optically superb.
Push the little catch on the zoom ring towards the front of the lens to unlock the zoom ring so you can turn it to the white dot.
To erect the lens for shooting, push the catch towards the front of the lens and rotate the zoom ring.

There is none on the camera or on the lens.
It is ON by default.
If you want to turn it off, look towards the bottom of the second red Camera menu.
As of 2015, this is the only ultrawide lens native to the Canon EOS-M system, and it is optically superb. Considering its very reasonable price, I'd strongly recommend it.
I'd use a Hoya multicoated 55mm UV to protect this lens. It's inexpensive and superb.
