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...

This 85mm focal length is perfect for portraiture as labeled by Canon and practicing professionals, due to the focal length creating just the right perspective for both the subject and the background. The 85mm is most commonly used for head and shoulder type portraiture, upper torso portraiture and selective floral photography. It will commonly be found in the kits of photographers that shoot wedding, birthdays, and other events involving people. These photographers would also carry a 70-200mm

Crop factor
In digital photography, a crop factor is related to the ratio of the dimensions of a camera's imaging area compared to a reference format; most often, this term is applied to digital cameras, relative to 35 mm film format as a reference.

 inherent with APS-C or APS-H (crop) sensor digital SLR cameras.

An example would be taking an image of a rock using two cameras with the same lens. The first camera a 18mp full frame and the second a 18mp APS-C, both shooting the same composition in a stationary position. The first image will be more "wide" while the second image will be more "magnified". After bringing the results into an image editing program and enlarging the first image so that the rock is the same size in both images, one will see that the enlarged image is approximately 160% (1.6x) of the original.

The major advantage to this extra "reach" would be the utilizing of the full sensor space for a cropped image rather than having to crop afterwards, thus utilizing parts of the sensor that would have otherwise been wasted. The major disadvantage would be the lack of change in perspective, since the focal length has not actually changed it will be like shooting with the field of view of a 136mm lens on a full frame sensor while having the perspective of 85mm lens. The resulting image will appear to have a less pleasing background blur and unlike using an actual 136mm lens on a full frame sensor. Some users will find that the crop factor actually benefits this lens since it is hard to get a tight framing around the head without running into the 0.95m minimum focus distance.

 speed of this lens is on the slow side when compared to most ring USM lenses, and photographing fast moving targets can be quite challenging with this lens. Manual focusing is done by wire: this lens does not have a direct mechanical connection to the focusing ring, but instead detects the rotation of the focusing ring and uses the autofocus motor to drive the lens elements. While full-time manual focus is available, the lens can not be focused when the camera is off. The front of the lens does not rotate, but does extend when focusing.

EF 85 mm 1.2L II USM

The newer EF 85mm 1.2L II USM version, which is aesthetically the same as the EF 85 mm 1.2L USM, is updated with a newer CPU, 1.8 times faster autofocus, and upgraded anti-reflective lens coatings to reduce chromatic aberration, ghosting, and lens flare.

EF 85mm 1.8 USM

The EF 85mm 1.8 USM is a consumer level lens. It is the shorter sister to the EF 100mm 2.0 USM, and is designed very similarly. It is constructed with a plastic body and a metal mount. This lens features a distance window with infrared index. An 8 blade, maximum aperture of 1.8, gives this lens the ability to create depth of field effects. The optical construction of this lens contains 9 lens elements, without any special lens elements. It uses an internal focusing system (meaning that the front of the lens neither rotates nor extends when focusing), powered by a ring type USM motor
