nice and small

  • Excerpt: Because of it's size I think this is going to be a good lens to take hiking and creating panos. Don't much care for the focus ring and find this lens to work easiest on a tripod when you have time to focus, not sure I would say this is good for catching fast moments. I realize the costs is low, but I still don't like Canon's trend of skimping on the lens hood and a lens bag.
  • Pros: Compact Size, Lightweight, Popular Filter Size
  • Cons: No IS, No lens hood, Thin focus ring, Tough To Manually Focus

Good lens

  • Excerpt: Between 40mm and 50mm, I like the 50mm better. However if you want lens particularly for portrait, I strongly recommend the 85mm.
  • Pros: Sharp images, light weigh, decent price.
  • Cons: Slow focus, cheap feels, not good depth of field.

Plusses and Minuses

Calaverasgrande, B&H Photo
7 October 2014
  • Excerpt: Bought this lense for street photography with my T2i. Together they make a nice small pair.The stm AF motor is not silent, but I really am not disturbed by AF noise. I prefer that it does make some audible sound to confirm that its doing its job.The viewing angle is kind of interesting. Not as tight as a 50 or as natural as a 35.
  • Pros: Lightweight, Nice Bokeh
  • Cons: Blurry Focus, Lens Creep, Poor in Low Light

Disappointed

Anatol, B&H Photo
6 July 2014
  • Excerpt: 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.
  • Pros: Lightweight, Rugged, Strong Construction
  • Cons: No zoom, Resolution Worse Than Kit

It it a good lense

  • Summary: The lense is good and i like it came with the filter. However, the lense hood will NOT stay on, very irritating. the problem with the lense hood is the reason for 3 instead of 5 stars.

The Jury's Still Out

Sean, B&H Photo
9 April 2013
  • Excerpt: I recently picked up this lens. For the price I couldn't resist. I've yet to use this lens on a regular basis, so the jury is still out. Autofocus is not as quick as with a USM lens, as to be expected, but this reminds me a little of the Canon 50mm 1.8 lens. Images appears to be sharp with a nice blurred background.
  • Pros: Easily Interchangeable, Lightweight
  • Cons: Slow Focus

* Consistently INCONSISTENT...

PerfectSavage, B&H Photo
21 January 2013
  • Excerpt: So first, I always rate relative to the price point, market segment etc. of the product. In other words, I'm not going to give a T3i two stars because it doesn't shoot 12 FPS or have 'x'D series camera body features... I always hate that, especially when you guys rate something like a Zeiss Distagon lens and say "I'd have given it five stars IF ONLY IT HAD AF"... Really? If you want AF, why buy a MF lens? AF has no basis in rating a clearly advertised MF lens..
  • Pros: Easily Interchangeable, Lightweight, Strong Construction
  • Cons: Inconsistent Exposure, Not An Outdoor Lens, Slow Focus

  • Conclusion: The lens, for the money, is pretty good. However....the contrast is weak and it seems to have some distortion. A 40mm really souldn't have much, if any, distortion. The latter is easy to fix in Lightroom, or DxO, but the contrast is difficult to remedy.
  • Pros: Fast auto-focus, good for the price.
  • Cons: poor contrast, overall distortion
