The Canon EF 135mm f/2 USM L is a highly desirable lens with excellent performance figures in most aspects. It is very sharp and contrasty straight from f/2 and it's outstanding at f/5.6. The bokeh is exceptionally smooth and buttery at f/2 and f/2.8 although it suffers a bit from bokeh fringing at these large aperture settings.

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.

A lens of this nature is a reasonably specialised piece of kit. It’s speed, both light gathering and focussing, make it ideal for indoor sport and event work. It also scores highly if you want portraits with OOF backgrounds where the focal length is near perfect.

It is very sharp, it is very fast, it is very well built and it is one of the least expensive L lenses Canon makes. If 135mm is the focal length you need, you will not be disappointed by the Canon EF 135mm f/2.0 L USM Lens.
