The Canon EF 40mm f/2.8 STM Lens is a unique and indispensable addition to Canon's series of EF lenses. The 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.

LOVE THIS LENS!
I am thrilled with this lens. I use it on my Canon T4i for video. It makes the camera much more discreet, portable and user friendly - especially when shooting kids: the camera with this lens is so light I can easily get down on their level and get some great angles. The quality of the footage is terrific, it is a little slow on auto focus, but I use mostly manual focus which is smooth and easy.

This prime was what I needed to photograph a play, on stage, from a fixed position without using flash.
I bought this lens as a walk around lens and for street photography since it is so inconspicuous and very light. I have L lenses but when I put this on a smaller Rebel camera I am very happy with it's clarity and versatility. It is a real bargain plus pairing it with a Canon 12extension tube gives you an awesome macro lens.
This is one of the sharpest lenses I own. That said, I own the EF 24-105mm f4/L IS USM lens. It competes quite nicely with that lens. Enough said.
This thin lens is the perfect walk-around lens for a full frame camera and a decent portrait lens for a APS-C camera. Just add a protection filter and a thin sun shade, and you are ready to cruse the boulevard.
I have been a photographer for 40 years. When I saw the price on this lens, I didn't expect much but bought it anyway. I love it. Sharp and great color. I leave it on most of the time now.
This lens just arrived yesterday and I think it will be just perfect for my purposes. I wanted a small lens to put on my 60D that had a large aperture ,a close focusing distance and did a decent job of rendering backgrounds out of focus. It allows me to fit my camera in my small purse/camera bag with room for the other essential I need. I great lens for everyday use and traveling light.
This is the best Canon pancake lens. Very small, light weight, yet the build quality is excellent, with metal mount and good glass. Image is very sharp, even at F2.8. Focus is very fast, even in live view AF mode. With the STM, you may override focus manually at anytime. The only issue is the manual focus - this is not a true manual focus, when you rotate the ring, the motor will drives the lens, at the same time it make some hmm noise, that is not good when recording video as the mic pick up the noise. Also the lens will not retract when the camera is powered off. So far, I am very happy with this lens.
I keep this lens attached to my 5D Mk III most of the time. It's sharper, smaller, lighter, and less expensive than my 50mm f/1.4, and so I'm only missing the low light performance.
I'm so impressed by this little lens. Super sharp and excellent bokeh. Just a sweet lens that makes shooting common item found in my yard so much fun. I just love it.
Love the size. Let's me put a decent lens on my DSLR and I don't have to worry about sacking it into anything. Makes my big camera seem small. It's a little slow to focus, so that's something I need to work on more when using it. I would recommend this to anyone looking to get a nice fixed lens where they want to have a lighter and smaller load to carry. I hope canon makes more "pancake" style lenses, especially wider ones.
