Great lens. Quite sharp. Accurate and fast focus. It's a joy to use. Of course, it delivers in terms of being compact. I'm using it on a 1.6x camera, so it's a somewhat awkward focal length. I look forward to the day I get to use it on a full frame. But you all know it's 40mm, so onward.

The mounting ring is really tight with my camera, and I have this feeling that I'm grinding something down when I mount or remove the lens. I don't think it hurts anything, so that's fine with me.

Unfortunately, the lens data is not pre-loaded on my t4i. But the image quality is so good that you hardly would ever need it. I will include a couple of photos. Both are unedited and were taken with in-camera settings neutral, and sharpness set to 0. The one of the leaf was taken with the lens wide open. You can see how quickly it passes in and out of focus. The background light shows the chromatic aberration about as badly as it ever gets, which is hardly at all! You can just barely see the opposing red vs. green fringe in the light. The one of the flowers is also wide open at 2.8, also neutral and unsharpened and unedited. With even the most light-handed increase of sharpness and contrast, stunningly crisp images, as well as softer ones, are at your disposal, and all at a ridiculously low price. I really like it, and it manages to jostle my other lenses off the camera which, on paper, should have much more versatility and utility.

Another note: The STM focusing is not silent. This is fine with me, but for those of you who might be interested, read on. In AF, there's a soft whine that it gives off, louder than my USM lens but quieter than my kit lens. In manual mode, the focus ring is, as many have pointed out, NOT a mechanically engaged gear, but rather an electronic input. When turning the ring medium to fast, it makes a lower and slightly softer hum. When turning the ring slowly, it makes a rather disturbing groan. However, when you turn it REALLY slowly, the focus moves with an amazingly controlled slow creep, and it's _completely silent_. That could come in handy for some nice cinematic effects.

I got this lens so I could take some more closeup candid photos of family on my 10D. It's been great. The low profile of it makes it more convenient in tight spaces and for carrying around. With its short macro distance I've also been taking some nice pictures of flowers.

The autofocus is a bit slow in my mind, but it's accurate. The lack of a distance meter is not too big of a problem. Its size made me a little wary about screwing it into my camera without breaking it, but it's a solid fit.

Comments about Canon EF 40mm f/2.8 STM Lens:

This is on of the best price/performance lens of Canon. Besides its image quality, the small size and lightweightness is its best features. Autofocus works almost perfect an very silently. The autofocus ring is a little bit tricky when you first use it because it does net work when the camera is off. Moreover there is a tiny delay with your ring movement and operation but this is not a big deal when you get used to.

      Comments about Canon EF 40mm f/2.8 STM Lens:

      This is one of my favorite and most enjoyable lens I us. I was looking for something with good enough picture quality and versatility that I did not have to be apprehensive about using on an entry level DRSL. They say 50mm is the standard, however the build quality of the 50mm 1.8 (plastic fantastic) was not up to my standards. In addition, having a crop sensor camera, 50mm is not a true 50mm anyway. At $, this 40mm lens does everything I ask of it and more. Nice bokeh, compact, versatile, lets in plenty of light (f2.8) and worry free. I would have given it 5 stars but this is an STM, slightest bit of noise when auto-focusing un-like other STM lens (which are completely silent).

          Comments about Canon EF 40mm f/2.8 STM Lens:

          For the money, this is one of the best general-use primes you can get. The optics are solid and the size and weight make it an great addition to any kit.

          The issue for me came from the focus. I'm a manual focus dweeb and, unfortunately, that's where this lens runs into trouble. It's focus ring is actually just an input to a motor. It's not terribly accurate, quick, or easy to use.

          That said, the auto-focus is fast and reliable. This issue comes from my love of manual focus.

          I may have traded up for a Voigtlander 40mm, but that doesn't mean you should. Unless you really like zone focusing and things made out of metal.

          Best Uses

            Comments about Canon EF 40mm f/2.8 STM Lens:

            That's probably due to my over-expectations. I compared this lens side-by-side with my EOS T3i kit lens (18-55, F/3.5-5.6) and discovered that my new EF 40mm f/2.8 STM gives LESS resolution than the kit lens. I set both lenses to F/5.6, manual exposure, zoom to 40 mm, and made tripod shots of bar codes. No doubt, kit lens was better. Then I checked Canon data (why didn't I do it BEFORE!), and their plots confirmed my conclusion. So, the only advantages of this EF 40 are: a bit higher F stop, and focus override. Minus ZOOM, minus IS, a bit heavier. Alas, I am going to return EF 40 because I see it unnecessary in my set of lenses. On the bright side, now I know that the kit zoom is a truly remarcable lens.

              I bought this to use on my 5d mkiii when I'm traveling and just generally out and about town - when I still want to still take nice shots, but not look 'professional' and without having to carry a bigger lens around. The 40mm pancake is great for that. Sharp, and in my opinion a perfect length and far more useable than my 50mm. Would love it if it came with a smaller lens cap - the stock one is nearly the length of the lens itself.

It can be a little difficult to navigate at first, especially with the limited frame that the lens gives you, but once you get used to it, it works great.

                        This is definitely not the sharpest lens in the camera bag but it is very small and light-weight. I use it to convert my professional DSLR to a handy "point and shoot" for general street photography, snap shots, and location scouting.

                        •I bought this lens for the specific purpose of making my camera as small as possible for casual shooting. There are definitely other options in this focal range and price range. I would recommend looking at different options in the 50mm category.

                                This lens is bright and tack sharp, corner to corner, even wide open at 2.8. Great colors and contrast. Focus is snappy even in extremely low light (it trounces the 50/1.2 and 50/1.4 at focusing). And it weighs nothing.

                                  I love this lens! It's a go to lens to just throw in your pocket when you go on a hike or are just running and gunning on a photo/video shoot. It producing sharp images, feels like quality and has the new whisper quite focus making to great for video. Best part of all is the price.

                                      I mainly shoot glamour, boudoir, lingerie, nude and wedding. Thought I buy this little lens to just try it out. When I brought it into the studio the first thing the model said to me was "what kind of lens is that" I guess she's was use to seeing the big guns like the 24-70mm 2.8 and 70-200mm f2.8 and others alike. But I did tell her it was a pancake lens 40mm f2.8 and she was surprised. Well from shooting with her that day, it gave me just the right range to zoom in and out with a little footwork. But good enough not to get in the way of other photographers. When I got home to do my post editing in light room 5 I was blown away how tact sharp the images came out. This I must say I can keep on my camera all the time as my favorite on the go to lens.

                                      Canon 5D MarkII & III 14mmL F2.8, 16-35mmL F2.8, 50mmL F1.2, 85mm L F1.2, 100mmL F2.8, 135mmL F2.0, 24-70mmL F2.8, 70-200mmL F2.8, 28-300mm L F3.5-5.6

                                      So far the 40mm f2.8 performs & I there are no Cons I can think of..........

                                        I am a wildflower photographer and I hike miles in search of my subject. I have to travel as light as possible. I shoot with a 100mm macro or a 180mm macro. I used to only carry one lens dut the the weight of an extra lens. Along the way I often see beautiful waterfalls and other great scenery. Wit the long macro lens I usually could not get good pictures of these. Now with this little wide angle lens I can get these great pictures and not increase my traviling weight.
