I bought this lens not knowing what to expect. It was my first prime lens which I got myself and for some reason, I picked this 100mm over the nifty fifty. When I finally received it, it was a really good lens. But when I kept using it over the months,...

Superb medium telephoto landscape lens on full-frame at apertures ranging from f/8-f/16. Clean and sharp edge to edge, nearly zero distortion, and great color/contrast. It's exactly what you want for professional landscape work. I only use prime...

This is the only non-L lens in my kit. It is often overlooked because of Canon's other 100mm offerings and some say that the 2.8L IS macro makes this lens redundant. If you shoot macro and want something that doubles as a portrait lens, then by all...

This lens is very well built, it may not be fully sealed but in my opinion that's the only thing stopping this having a red ring. The lens does not move either the front or rear element for focussing which means it is naturally reluctant to attract...

Despite its age, that's still an amazing lens. Unfortunately, it lacks the stabilizer and the AF is not up to the best Canon lenses, but other than that, this lens is just great. Distortion is negligible, vignetting is very well controlled and...

I love this lens, I use it on a Canon 5D Mark II for very low light theater photography and I get some really stunning photographs. Even in situations when there is almost no light I am able to obtain really good results.

This is an amazing and affordable mid-range prime lens. Often over shadowed by the 85 f1.8, the 100 provides a little more reach for those of us that don't like to be too close. The bokeh is smooth, the images sharp. The focus is acceptable, however,...

Yes- its better than the 85. Buuuuut both are loooouuudddd when autofocusing... I wish they would come out with a mii with a silent autofocus. It sounds like someone is chattering their teeth... Other than that, great little lens for portraits and...

If you can only buy one prime and shoot a lot of heads the EF 100 2L USM is the one to buy! Oh sure the EF 135 2L USM may be a bit sharper on film or high-end FF EOS 1Ds XX body and it is a lot more sexy than the more pedestrian EF 100 2 USM. But what...

I recieved this lens for Christmas, hoping for a great portrait lens. And I got just that! This lens is amazing for portraits! The Bokeh is soo buttery! The colour and contrast are right on, and the sharpness is like a razor! Great great lens! The only...
