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.

It′s amazing, especially for night shoot′s, I'ts light and inexpensive in comparison to others. It′s perfect for low light shots and you will never regret getting it nor will ever let it go.

Pancake lenses have come into some popularity in recent years, and Canon has answered with their own version, the . Some may question the point of a fixed lens that is only f/2.8 these days, but there are plenty of reasons to pick up a lens such as this.

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.

There was a lot of hype after Canon's release of the 40mm pancake lens & I wondered if it was worth getting this inexpensive prime lens versus saving up for L glass for 10X or even 20X the price & made the leap when the price dropped.

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 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.

Canon's new standard fixed 40mm lens is so slim and light (just under 3cm protruding from camera body to lens cap edge and weighing 130g) it can slip into a gear bag or pocket with little bother.

Versatile; small and light; Sharp images; Silent autofocus in video mode on 650D and 5D Mark III

Auto/manual focus switch a little fiddly; Quiet autofocus feature only with the above models

Canon has launched two new lenses with the EOS 650DRebel T4 DSLR - the EF 40mm f/2.8 STM and the EF-S 18-135mm f/3.5-5.6 IS STM, priced at £229.99 (about $355) and £479.99 (about $740), respectively.

I love this lens. I prefer to use prime lenses over zoom lenses and I bought this lens to replace the "nifty fifty" that was recommended to me when I bought the camera body. This lens is a much higher quality and takes better images. The auto focus mechanism is also a lot more responsive.

High quality construction; compact size; amazing price
