Despite the large maximum aperture, the lens remains compact. Lens group 5 moves for rear focusing, and sharp, crisp pictures are obtained at all apertures. The background blur is ideal for portraits. The USM autofocuses the lens quickly and quietly.
I love this lens
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.

Excellent mid-range prime
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, does hunt in low lighting, despite the f2.
I have "L" lenses, and I can honestly say, this is one of Canon's non "L" that feels, shots and performs like it deserves the red strip. Excellent lens.

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 candids- long but small so people dont know ur taking a photo of them... Get it!

One prime and shoot heads, look here...
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 the EF 2 USM lacks in sexy it gives back in real world image quality, much lighter weight and saves you enough money to buy another good prime. This is another workhorse lens that splits the range between the EF 85 1.8USM and EF 135 2L USM and because of it is less narrowly defined in what you can do with it.
Depending on your EOS sensor format it can be used for a lot of different subjects and can produce very fine images if you do your part. A bit more money for some reason than the shorter faster EF 85 1.8USM but has the extra reach you may need or want on a smaller format chip EOS body. Similar build to the EF 85 1.8USM which is to say solid feeling with fast and quiet focusing. Another excellent image and value lens IMO.
