Canon 100mm f/2.0 USM EF Lens
Going with a fixed lens sacrifices some versatility but typically offers much more speed. This midrange telephoto has a nice f2 maximum aperture to let in plenty of light and shoot at faster speeds than with a f4 zoom lens. The larger aperture also allows for softer backgrounds and a more dramatic bokeh effect. The lens is also compact and weighs just a pound. Canon designed this model in five groups, allowing for the rear focusing function. The USM designation in the name means it includes Canon's ultra-silent motor for quiet yet speedy focusing. The lens doesn't include image stabilization, but it isn't as much of a necessity at this midrange 100mm.
