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.Read more ›
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!Read more ›
A quick note about me: I have been into SLR cameras and lenses for more than 20 years - as a hobby in the beginning and professionally later. Maybe because of my technical background I started testing my own lenses quite a while ago. I have a (no longer so) little test lab of my own where I do 6 different image quality tests (after taking a lens out for a while).
Canon's first-ever "pancake" EF lens is a real treat. It's so small that it looks like a 20 mm extension ring rather than a lens and yet it feels solid as a rock and delivers very respectable image quality. It comes with Canon's stepping motor technology (STM) that allows continuous AF during video recording or live-view mode (when used with a hybrid CMOS AF system) and that gives the lens a fast, silent and accurate autofocus performance. The EF 40mm f/2.8 STM is best used for street and travel photography but can also make great portraits or other things. Its maximum aperture of f/2.8 is great but not good enough for available light photography (which requires even lower f-stops i.e. wider apertures) and I would have loved to have an image stabilizer - but of course that would have been very difficult to build into a 2.7" x 0.9" (68 mm x 23 mm) lens.
In regard to image quality the EF 40mm f/2.8 STM is really a high-end lens. The difference is most apparent if you compare it to a zoom lens but also amongst prime lenses of similar focal length the EF 40mm f/2.8 STM is a high performer. The resolution is great straight from f/2.8 both in the image center and corners.Read more ›

Nice small normal to have on hand for general use. Small size is perfect when you need to travel light and/or need to be a bit less conspicuous. Great bang for the buck. Read morePublished 3 days ago by J. Harrison
Great lens, you can get pretty creative with it. I am really enjoying it so far!Published 5 days ago by kwin91
This lens does perfectly the things it purports to do. Using it on a 5d Mark II is fun. It focuses a lot more accurately than the 50mm f/1. Read morePublished 12 days ago by Blunt But Honest
I totally love this lens.
Perfect shallow depth of field.
It's a small frame than normal, keep that in mind.
