The Canon EF 135mm 2L USM is a short-to-medium
telephoto lens
A telephoto lens, in photography and cinematography, is a specific type of a long-focus lens in which the physical length of the lens is shorter than the focal length. This is achieved by incorporating a special lens group known as a ''telephoto ...

photographers, the lens is highly regarded for its sharpness, contrast, and
color rendition. The lens is also popular because it is very sharp at its maximum aperture of 2, allowing the photographer to throw the background out of focus while recording a lot of detail on the primary subject. This gives the photographer fine-grained control over
depth of field
The depth of field (DOF) is the distance between the nearest and the furthest objects that are in acceptably sharp focus in an image captured with a camera.
Factors affecting depth of field
For cameras that can only focus on one object dis ...

In photography, soft focus is a lens flaw, in which the lens forms images that are blurred due to spherical aberration. A soft focus lens deliberately introduces spherical aberration in order to give the appearance of blurring the image while ...

in 1987 designed for portrait photography.
This is the only EF lens that has soft focus capabilities, allowing the user to control the lens's correction of spherical aberration. This feature is controlled by rotating the soft focus selector which has three choices; 0, 1, and 2. On the 0 setting, it functions as a standard 135mm prime lens. Settings 1 and 2 adjust the amount of softness in the focus. This is done by rotating elements that are inside of the lens to create deliberate
spherical aberration
In optics, spherical aberration (SA) is a type of aberration found in optical systems that have elements with spherical surfaces. Lenses and curved mirrors are prime examples, because this shape is easier to manufacture. Light rays that strik ...
.
Due to its old design, the 135mm SF does not feature
USM technology; rather, it uses
arc-form drive technology. Despite this, focusing is quite fast and reasonably quiet. Since focusing is achieved with the rear element, the front element does not rotate or extend. The lens supports all 52mm filters.
The lens can be used with any camera that accepts EF lenses, but cannot be used with Canon's teleconverters.
