All three of these lenses are well-constructed and light weight. They are all ultra-fast focusing and produce high contrast images. They differ in resolution, 50% MTF (microcontrast), and background blurring (bokeh) produced as outlined below.

If I had to use one word to describe this lens, it would be CONSISTENT! My samples below look like I posted the same picture repeatedly (except for the color shift as noted): from f/2 through f/22 there is almost no perceptible difference in sharpness!

You can't go wrong with this lens. If you're trying to choose between this lens and the 85/1.8, decide what kind of portraits you want: standard looking, or a little more punchy. The subjects I shoot like creative Images, so I use the 100.

The 100mm focal length combined with the wide aperture makes this a very good portrait lens. Selecting the length of a portrait lens is a combination of functionality and personal preference. 100mm falls in the middle of my 85mm-135mm preference for a portrait lens.

The Canon EF 100mm f/2 USM is one of the "can't loose" offers in the Canon lens lineup. It performed almost flawlessly in all tested categories. It's interesting that the figures are marginally better compared to its more popular sister lens (EF 85mm f/1.8 USM).
