Review summary from DPReview
The EF 40mm F2.8 STM offers excellent image quality in a tiny, well-made package. For APS-C users it provides a great carry-everywhere complement to a kit zoom, and for full frame shooters it's an excellent general-purpose 'normal' lens. The STM motor means that autofocus is almost completely silent, but it's not super-fast.
Scoring is relative only to the other products in the same category.

I had the pleasure of owning the Pentax and Contax Zeiss lenses in the days of film. I loved them both, and they were never far from reach. When I bought Canon dSLRs, due to lack of any Canon pancake lens being available, I adapted both the Contax Zeiss and the Pentax pancakes to work on my 5D, 5D2 and 40D. Of course, this arrangement has serious limitations, as both the autofocus and the aperture have to be set manually, making for a slow, awkward shooting experience. At very long last, Canon has brought its own pancake lens to market, in the form of the EF 40/2.8 STM.
It is strikingly small and light, and if you've never seen or experienced a pancake lens before, you're likely to wonder how a lens can be so small and even work on full framed dSLRs. Despite its size, there is pleasing build quality to be found. Built nothing like the EF 50/1.8 II, there is a metal lens mount and a solid lens barrel, short as it is. Canon was barely able to fit the AF/MF switch on the barrel, the barrel is so short. I would compare build quality to the EF 50/1.4. Aesthetically, the 40 has a sex appeal all of its own. There's always been something about those pancakes and they way they look and feel. Canon certainly does not disappoint here.
Optically, I have found the 40/2.8 to perform in excellent fashion. CA is well-controlled, I have not experienced problems with flare, and I do not have a hood attached. Center sharpness at f/2.8 is excellent, and I have uploaded a photo here to help demonstrate. Corners look very good as well. Color rendition is excellent, and bokeh is much to my liking.
Mechanically, the AF is fast, quiet and accurate, and the new STM focus stepping motor technology is employed here. I don't shoot video, so I couldn't care less about the lens being quiet for filming of video, but that may we a huge deal for those of you that do use the video features of your dSLR.
While Canon points out that this lens makes it possible to shoot more discretely, I suppose that's true to a point. But it's rather difficult to achieve shooting discretion when the lens is mounted to the larger non-Rebel Canon bodies, being the big black blobs that they are. However, the pancake design does make your shooting experience very pleasant in that there is not a long lens sticking outing of it. Combined with the weight reduction, the shooting experience with this lens mounted to your camera is bliss. I will be using it a lot as a walkaround, and for vacations.
A possible issue with this lens concerns its use with a cropped sensor camera body. The crop on the 1.6x bodies results in a 64mm effective focal length. I'm not sure how useful a 64/2.8 lens would be for most shooters. For me, that's not very useful. You may disagree. I'll vouch for the usefulness of this lens on a full frame body.
I highly recommend this lens, and at this price point, it's a no-brainer to click the Buy button.
To give some background: I do shoot professionally, but got this lens mostly for personal use - I simply prefer the versatility of a zoom lens for professional work, although seeing the impressive results I might incorporate it for future assignments. I currently own two bodies, a 5D Mark II and a 7D. While my main lenses are high-end (the 24-105L, 70-200L 2.8 IS II, and 100mm Macro), since I started off with a Rebel series body I also am familiar with a lot of the cheaper lenses Canon sells, including the 50mm f/1.8. I really liked the 50 f/1.8 because of its convenient size - but by comparison to this lens, it now seems big!
I love this 40mm f/2.8 lens on both of my bodies, but find its focal range to be much more useful on a full-frame than crop-sensor body. Keep in mind that if you have a crop body, the effective focal length of this lens comes out to 64mm! Even at that length, you can still get impressive shots with beautiful bokeh, but in my experience 64mm was more inconvenient to work with than 40mm. I'd still recommend it for APS-C bodies though, because the image quality thus far has been very impressive.
* Very small lens, which allows for much more inconspicuous shooting if you want to blend into the background. This lens is tiny! Yes, mounted on a battery-gripped SLR you still stand out a bit, but not nearly as much as you do with most other lenses
* Very light - this is much more portable than any other lens I own. You could even carry it in a pocket.
* Great image quality. I really am impressed at the results based on the low price point
* Impressive build quality. This lens might be inexpensive, but it doesn't feel cheap.
* Hard to manually adjust focus. This is my only major gripe with this lens. It is doable, but it definitely takes getting used to. This is especially pronounced if you have big hands. That being said, I think the convenience of the small lens size makes up for this minor inconvenience.
* Yes, as some other reviewers have already mentioned, there is some vignetting wide open. This doesn't bother me too much as I find the vignetting to be acceptable, but some others might not like it even if it can be corrected in post-processing - it depends on personal preference
I will try to upload photos demonstrating this lens' ability in the next few weeks; in the meantime, some people have already added to the gallery here, and undoubtedly many pictures will start appearing on Flickr.
Some people will inevitably find the need to ask why I gave the lens 5 stars if there are some cons. For the price I paid for this lens, I am very happy with my results, and think the cons are outweighed by the pros. The size and weight of this lens are remarkable, and its optical performance is great for the price. Sure, you could compare this lens to much more expensive ones and find more shortcomings, but I think for most people's use, this lens is a terrific buy. The other reviewers thus far also seem to be happy with their purchase, which I think is a testament to the performance of this lens. I highly recommend you go for it!
