Summary: I purchased this lens due to the multiplication factor of Digital Cameras. This lens works as a normal size focal length and the wide open f-stop gives it excellent used in low light situations. I'd recommend to family and friends.
Summary: I am a prime lens lover for the lower apertures, and this was a great addition to my Canon EF 50mm f/1.8. It's a relatively small lens and weighs next to nothing compared even to some standard zooms. Tack sharp all over once brought down one stop. Plus, it has a metal mount, reasonable filter size, and extends hardly at all while focusing (maybe half an inch).
Summary: I bought this lens for it's low light capabilities and I was not disappointed. I used it for inside shooting w/out a flash and "freezing" action in good light like hummingbirds. Very "fast" lens. I eventually sold this for it's slightly sturdier and a little faster cousin the Canon 50mm 1.4. Honestly I don't see a huge difference. This is a good bang for the buck lens.
Decent Lens for the Money, hard to beat it for how usefull it is!

Summary: Decent Lens - I'm a pro photog, and use mostly primes, and this was all I could afford for a true 28mm prime... the 2.8 is fast enough for me for what I need it for... but it is a little bit fuzzy at the corners at f/2.8 - at f/4 it's much better for sure... I like it too, because it is very close focusing, and if you need a lens for this, you can't beat these... it is not a MACRO lens, some people get that confused... close focus and MACRO are 2 separate things...
Summary: I have been happy with this lens so far, using it on a Canon 30D body. The glass is decent quality, without any significant vignetting. It's not particularly wide angle, due in part to the 1.3 magnification factor on the 30D, so not great for getting the full room at a party for instance, but works well for landscapes and such.
Summary: I purchased a MK I version of this lens, have not seen the MK II but apparently it does not have the metal mount that this one does. I like the wide angle, which on a crop sensor like my Canon XTi effectively makes it a 45mm. It's great for portraits, for outdoor shots and even for some impromptu macro work. Almost as fun as the 50 1.8 for the money and playing with low apertures and skinny depth of field.
Pros: Sharpness, weight, size, value
Cons: Hunts a bit in AF, A bit noisy, plastic and obviously feels less substantial than a heavier metal lens. Decide for yourself what significance these characteristics mean to you.
Summary: Great price for this 2.8 lens if you do a lot of architectural work. On a crop factor body (I used it on a 30D and 40D), it produces virtually no distortion. Only gripes are that is focuses slow and noisy.
