Wait!!!! It's Sharp!!! Well, the review is for all those who are in dilemma between 50mm f1.8 and 40mm f2.8. On the spec sheet one would think that 50mm beat the hell out of 40mm, with it's larger aperture and better focal length for portraits.

The lens provides excellent auto focus for both video and still. I am using the lens in EOS-650D which gives an excellent clarity for portraits and closeups.

Fast / accurate auto-focus; Nice Bokeh

Lens Creep

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.

I bought this lens as a walk-around lens. It is not as fast as my 50 1.2 but is much much lighter and most important, do not draw attention. It makes my 6D looks very discrete. It is also cheap for what it delivers.

Small; light; small and light again..; Superb sharpness even wide open; Don′t draw attention at all...

STM focus wont manually work in auto mode; In manual mode still has an delay, You cant operate focus if camera is turned off or if the lens is detached, making impossible to retract the front element, It is quieter than old focus systems but is still audible

This is an exellent lens,I use it mayly for head shots,but for my porpose,I but I rather use the24mm f/2.8 STM,to me its the perfect lens for all an around lens unless you want to use a zoon lens.

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.

This Lens has been Awesome taking Christmas Pictures Lens it's great in low light and the STM is amazing for Video I have this and the 50mm f1.8 and I use this 99% of the time absolutely amazing little lens makes the Camera almost compact I use it on the Canon T5i and no regrets in buying it and I...

Wont feel lazy to carry this everywhere i go - Fits well on my 7D and now its easy for me to carry my camera ever were for clicking desert pictures.

Amazing quality ; Original; Compact and good for carrying everyday

Absolutely Nothing

The 40mm "pancake" lens from Canon is the first prime pancake lens that Canon has released. I purchased this lens about 5 days ago, and I took it with me on vacation to Asheville, NC. I used it to do some street photography on my EOS 70d.

I really didn't feel this was the lens for me, quite slow to focus and not as good as its 35mm and 50mm counterparts
