"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. It is the highly regarded Canon EF 135mm f/2.0 L USM Lens. If 135mm is the focal length you need, you will not be disappointed by the Canon EF 135mm f/2.0 L USM Lens. " the-digital-picture
"One of Canon's best lenses, the 135/2 L has superb optics in a compact package with great ergonomics and immediate autofocus. Lenses like these simply aren't available for Nikon, which is why so many professional photographers prefer Canon cameras. All of Nikon's 135mm lenses have goofy autofocus controls." kenrockwell.com
"The fastest 135mm telephoto lens in its class. Ideal for indoor sports and portraits with background blur. Two UD-glass elements correct secondary spectrum for outstanding sharpness and color. Compatible with Extender EF 1.4x II and 2x II" dpreview.com
ngutip kata2nya dari para reviewer site,, pokoknya lensa ini dewa banget masbos,, sebelumnya pernah make 70-200 F4L dan 17-40 F4L dari Image Quality-nya masih lebih oustanding 135mm F2.0 L.. bokehnya sadis.. >.<
"if you have Canon gear, then you have to try this lens before you die!! wkk :D "
