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.
This lens might be the best buy of the entire Canon line of lenses..I tested the canon 40mm against the 40mm f2 from Voightlander and was pleasantly surprised by the Cannon.I'm not going to say that the Canon was better in every way; but as far as center sharpness goes, I was amazed. I found my copy of the 40mm f2.8 pancake to be sharper in the center for all f stops untill f16 when Voightlander catches up. At f22 the voightlander is sharper. At 5.6 and F8 canon was quite a bit sharper.
I own 5 other canon lenses (all "L" glass). For the price difference, this little knock around lens is amazing.

I recently purchased the new 70 D body, I am never that fond of kit lenses so this is the first lens I decided to purchase to go with my new camera. I am in love with this lens. It is such a fun lens, it really captures the colors of the scene you are shooting well, and for the price the quality of the photos are great! If you are a intermediate photographer like me I know you will not be disappointed! This was actually my first stationary lens, I usually shoot everything with a wide angle zoom or a regular telephoto zoom, this lens has made me so excited to purchase another stationary lens. I see the 85 mm in my future:)

Great Compact Lens
I love the Canon EOS 40mm cause it is a great travel lens. It is also tack sharp because it is simple and only has 6 elements (pieces of glass). Since it weighs next to nothing, it definitely lightens the load of my 50D with accessories, which weighs almost 10 times more than the lens itself. I would definitely recommend this to someone with a full frame camera (6D, 5D, 1D) or to somebody with a ASPC camera (All Rebel models, 10D, 20D ... 70D) that wants a more zoomed in image.

Best Full-frame focal length and lens size
I am soooo happy canon made this lens. It really is the PERFECT focal length and size all in one camera. This lens will absolutely put the fun back into your photography days.
To say the least, 40mm on a full frame is not too sweet, not too sour, but just right. EVERYTIME! It's size and PRICE allows you to tote it around and ENJOY yourself. Thank you god! Geez. I've been waiting a looonnnggg time for something like this.
Canon.... please develop the 40mm focal length more. And please develop pancake lenses more. Pancake lenses are the future for anyone who wants to enjoy their DSLR. I can now carry my 6D everywhere and carry my children when I need to. It is 10x more easier to carry around than the 50mm f1.4. THAT is saying quite a lot.
