EF 135mm 2L USM

The Canon EF 135mm 2L USM is a short-to-medium telephoto lens
Telephoto lens
In photography and cinematography, a telephoto lens 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 group that extends the light path to create a long-focus...

Lens speed refers to the maximum aperture diameter, or minimum f-number, of a photographic lens. A lens with a larger maximum aperture is a fast lens because it delivers more light intensity to the focal plane, allowing a faster shutter speed...

Aperture
In optics, an aperture is a hole or an opening through which light travels. More specifically, the aperture of an optical system is the opening that determines the cone angle of a bundle of rays that come to a focus in the image plane. The aperture determines how collimated the admitted rays are,...

 ideal for both of these applications.

Among Canon photographers, the lens is highly regarded for its sharpness, contrast, and color rendition. Arguably, Canon's sharpest lens to date. 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

EF 135mm 2.8 with Softfocus

The Canon EF 135mm 2.8 with Softfocus is a soft focus
Soft focus
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 retaining sharp edges; it is not the same as an...

 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
Spherical aberration

 technology; rather, it uses arc-form drive technology. Despite this, focusing is quite fast and reasonably quiet and, 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 use with any EF camera but cannot be used with Canon's teleconverters.
