A unique and indispensable addition to Canon’s series of EF lenses, the new EF 40mm f/2.8 STM offers an ultra-slim and lightweight design. Incredibly compact in size, the EF 40mm f/2.8 STM delivers high image quality from the center to the periphery thanks to its advanced lens configuration including an aspherical element, a bright 2.8 aperture, and optimized coatings that minimize ghosting and flare while providing exceptional color balance. The EF 40mm f/2.8 STM’s unobtrusive design helps the photographer avoid overwhelming their subjects with a large lens and to remain discreet in sensitive shooting situations with no compromise in performance. Its diminutive design is complemented by features such as a newly developed stepping motor for smooth and quiet continuous AF while capturing video with the Canon EOS Rebel T4i DSLR, a circular aperture (7 blades) for beautiful soft-focus backgrounds, and a short minimum focusing distance of only 0.98 ft./0.30 m.1-Year Warranty

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.
CONSTRUCTION: Although a small lens, it feels solid in hand, boasting excellent build: metal mount, beefy plastic barrel and comely industrial satin finish.
STM AF is not silent but makes a soft electronic intonated "sheeeeet," resembling a sound effect from Tron. Most built-in camera mics will pick it up during video recording. The work around is to use an external mic or prefocus before the clip. Focus is slower than ring-USM but silky smooth. The motor uses "focus-by-wire" manual focus. The focus ring isn't mechanically coupled to the lens, but is a simply a switch for activating the focus motor. MF is smooth and accurate, albeit slow. The gotcha is it is only active when the shutter button is half depressed. The nested barrel extends during focus operation.
I use the EF 40 2.8 STM on a 6D, 5D MKII and SL1. AF is dependable on the 5D MKII and 6D, but randomly misses focus on the SL1 about 15 or 20% of the time. Other lenses are fine on the SL1.
IMAGE QUALITY: Wide open at F2.8 my first copy was sharp in the center of the frame but suffered with extremely soft corners on both full frame and APS-C. Corners improved when stopped down to F8 but were still unacceptably soft. Night images with points of light exhibited severe coma (comet-like tail) at F2.8. Stopping down reduced but didn't eliminate coma.
For the above reasons, I returned my first copy and bought a refurbished EF 40 2.8 STM from Canon Direct (with a big discount!). What a difference! Wide open, it was even sharper--deadly sharp--in the center. Corners were greatly improved but still slightly soft on full frame. On APS-C the corners were nearly as sharp as the center. And coma was greatly reduced: no coma center frame at F2.8 and only slight coma along the periphery. So second time around a home run!
Defocused areas (bokeh) have a pleasantly smooth swirl to them at F2.8, helping offset subjects from background. I find 40mm a natural snapshot FOV for full frame cameras like the 6D. The slightly wide view is perfect for landscapes and environmental portraits. Keep in mind, on APS-C cameras, e.g., 60D, 70D or Rebels, FOV is a 64mm equivalent, falling within the realm of short telephoto.
LENS HOOD: Canon makes a dedicated hood for this lens, the Canon ES-52 Lens Hood. It's just a 52mm aluminum filter ring around a disk with a hole in the center. It provides some shade but not much. The 40 2.8 is so popular there's a Chinese knockoff of the ES-62 available for a few bucks less: RainbowImaging HES52 Metal Lens Hood for Canon EF 40mm F2.8 STM. If you want more protection, a generic screw-in type like the RainbowImaging HM52 52MM Metal Lens Hood is better but will spoil the minimalist pancake vibe. I elected to use the ES-52, buying when the price drifted down to $18.
LAST BLURB: Normally $150 doesn't buy much in terms of optics but the EF 40 2.8 STM is the exception to the rule. This lens is sturdy, renders beautiful images and is barely larger than a body cap. If you get a good copy, it's an excellent optic. A basic 6-element design and offshore manufacturing (Malaysian factory) helped reduce costs but compromises in quality control were obviously made to maintain this price point. Test your lens for sharpness and coma before the return period is up. If Amazon delivered a sharp lens the first time, this would be a 5-star review. Nevertheless, I got a great sample the second try so it ended well after some toil and hassle.
