this is not the lens for everyone. Some might want faster lens or even the L-brand. For me, this one is a PERFECT lens for street. Optically superb & sleek design. Nobody's gonna be intimidated with this tiny lens. a perfect lens for fullframe sensors. Price is highly acceptable.

sleek; very light; SHARP! nice build quality.

I should say this is a great value for what it is: a sub-$200, fast 40mm EF lens with well regarded sharpness stats even wide open. Where the EF 40mm f/2.8 STM is a huge letdown is in the realm of video. There is distinct and audible autofocus hum that is recorded on your video.

A great walk around that is perfect for low light situations. This is a lens you will be happy with because of its STM abilities,of its weight and the quality of construction and picture quality.

I'm new to the land of DSLRs and this is the second lens I've bought for my T4i. I don't particularly like the autofocus on this lens. I don't use it often, but there have been a couple of times where I needed it and it was a bit too slow. Other than that, I think it's nice lens.

40mm might appear to be a bit of an odd focal length for a lens, but after spending a week with Canon's first pancake lens, it makes complete sense on our crop-factor EOS 60D.

I bought this as an in-between lens, between my wide 16-35 and zoom 70-200 and as a potential video lens (not tested yet) on a 5Dmk2 First impressions were how small it is making it very unobtrusive, yet the manual focus ring is easy to use unlike the 50mm f1.8 On the occasion I tried it for...

Great Picture Quality; Lightweight; Simple Controls

This is my second of these. It is better value, better build, and picture quality than the basic 50mm Canon lens. It's a tough little thing and I use it about 80% of the time compared with my other lenses.

Works great on my T4i, but not as silent as I had expected. The 18-135 STM lens is silent and I assumed this one would be equally as quiet, but the buzz of the motor is audible and is quiet video situations you do pick up the buzz of the autofocus.

I didn't buy the nifty fifty due to its somewhat low build quality. So when this lens was announced in the 'cheap enough not to really worry' price bracket, I snapped one up. I think with the EF 40mm pancake, Canon have the balance right. It's not an 'L' lens but does have a metal mount.

Had this lens for a few weeks now and I find myself using it more and more. It is a great all round lens delivering high quality images and for street photography it's a must have. Good value for money.
