This lens is a great compact lens. If you wanted to travel as light as possible, this is a great choice. It is wide enough for scenic shots, and great for street and distorted people shots. I wish this version had an Ultrasonic motor, but for the price, I can live with the buzzy motor.

I wanted a small, wide autofocus prime lens for my full-frame Canon 5D. I already have a superb 24mm lens - a tiny Olympus 24mm f/2.8 that I use with an OM-EOS adapter - but I find myself running out of patience with manual stop-down and zone focus.

Sharp in the very middle at all apertures; sharp almost to the corners at f/8; small; light; good colour, contrast

Feels redundant - you really have to want it; overpriced; physically old-fashioned

This is one of the truly &#147MUST HAVE&#148 lenses for almost every Canon EOS SLR camera bag.

NO DISTORTION! WOW! Nice n' Fast * "L" Class Resolution

Not As Quiet As A USM; But So What

I bought this lens to widen the views possible on my EOS 10D. The build quality is great. It feels like a little tank compared to the 50mm f/1.8. It's only sliiightly larger but nicely heavier than that lens. But, check the weaknesses....

Depth of field is great; The horribly wrong autofocusing is quick, and f/2.8 ain't bad either; Build quality is great; It feels like you could throw it at someone, hurt them, and pick it up and use it again

Here's the main problem: It brutally overexposes everything on my 10D; It's not reliably "x stops off" of you would simply set some exposure compensation whenever you mount it on your camera; It's very hit and miss.

I had to wait 2 months for this lens to arrive. I even tried to cancel the order but it was too late. It arrived. 30hrs later .. I accidentally threw it onto concrete and the front glass had a crack and the barrel filter ring dented and some plastic bit in the front was shattered.

Superior build quality; Super-sharp images

Yes, I would recommend this to a friend

For those of us closely following Canon's lens line, the Canon EF-S 24mm f/2.8 STM Pancake Lens looks exactly like a very successful lens we have seen before. That lens is the first Canon pancake-designed lens compatible with EOS DSLR cameras, the Canon EF 40mm f/2.8 STM Lens .

Primarily a macro photographer, I wanted to try my hand at wide angle nature photography. The 24mm lens is absolutely fantastic, sharp, durable, and was very easy to get the hang of. Very inexpensive as well! I love the focusing distance- enlarged subject up close with a nice bokeh background.

Previous reviews are for other Canon 24mm's. The Pancake STM is just now released and got my copy yesterday. Small (same as 40mm), sharp, small and sharp. Perfect for what it is, small and sharp. Disappointing Canon didn't improve small STM motor over the 40mm as it is audible on my SL1.

Sharp; Small

Stm Not Quiet Enough

I'm going to say that this lens is pretty good can make some very good lenses the one thing that I was expecting from this lens was more sharpness for middle of the road performance I think it's a good lens but I have a tokina 11-20 which is much sharperso I think can and could have done a better...
