This is one lens I wish I had the opportunity to shoot more often. The combination of the bokeh and depth of field is like no other. It produces a "3d" effect at just the right distance. If I didn't mind shooting so long or if this lens had IS, I'd probably be better friends with her. The 135L is like a very fancy date who refuses to take anything less than extraordinary.
The fastest 135mm telephoto lens in its class, the Canon EF 135mm f/2L lens is ideal for indoor sports photography and portraits with background blur. Although the lens offers complete automatic focusing capabilities thanks to its Ultra Sonic Motor (USM), you can still take advantage of its manual focus function even when the camera is in AF mode. The lens also offers two UD glass elements that help minimize chromatic aberrations, giving your images outstanding sharpness and color. Other details include a 3-foot close focusing distance, an 18-degree diagonal angle of view, and a 72mm filter size. The lens--which is compatible with EF 1.4x II and 2x II extenders--carries a one-year warranty.
