The 4 non-IS version, the cheapest L-series lens that Canon makes, is popular among weight-sensitive landscape photographers and hobbyists who want L lens quality without spending thousands of dollars. The 2.8 versions are popular among event photographers and photojournalists; some portrait photographers also prefer this lens. The IS version lenses use circular 8-bladed diaphragms which maintain a nearly circular aperture when stopped down by up to two stops. The 2.8 and 4.0 image-stabilized versions also feature weather sealing (resistance to dust and water) when used with a weather sealed camera to match such as the 5D Mark II

of this lens is equivalent to a 112-320mm on an APS-C sensor, or 91-260mm on an APS-H sensor. This is due to the crop factor
inherent with APS-C or APS-H (crop) sensor digital SLR cameras.

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...

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,...

The focal length of an optical system is a measure of how strongly the system converges or diverges light. For an optical system in air, it is the distance over which initially collimated rays are brought to a focus...

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. In the case of digital cameras, the imaging device would be a...

Switches
