Summary: This is my sharpest lens period. When range is not an issue, this is the one I use. I use this on a D70 and T3i both of which are crop sensors. This gives an effective focal length of 44mm which puts it between 35mm and 50mm. For me this is a sweet spot.
This is an essential lens for Canon 5D cameras, as well as for Rebels.

Summary: This lens is a normal lens for Canon Rebel cameras. For the larger Canon 5D cameras, this lens is 50% more wide than a normal lens. With a fixed focal length, it is sharper and brighter than the corresponding setting on the kit zoom lens. The focus motor is noisy and the build quality is not a match for lenses in the luxury class. I am delighted to be able to use this lens.
Summary: It's a great lens in the item cost x benefit. Consider the Canon FD lenses of high standard. And she with 28mm focal length equivalent to 42mm on a DSLR with an adapter. It's good overall quality, sharpness and contrast even at 2.8, but are excellent with f 4.0 to 8. Recommend for use with the Sony NEX adapter.
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: My son has recently begun a career as a professional photographer and as a good luck gift I ordered him this lens. He does a lot of weddings and realized he had a need for a 28mm f/2.8 lens for some of his group shots and interior distance shots of the services. When he got the lens he put it to use right away and the results were cool! It's a real high quality lens that Canon has built to it's exacting standards. (One of these days I'll get one for me, too!
Summary: I am currently going back to collect older FD mount lenses to use with my AE-1 Program. I am also using these to mount to my Olympus OM-D E-M5 camera, which make it an amazing photo machine. JPEGs render great with this camera and FD lenses attached.
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).
