The EF 16–35 mm lens is a family of professional wide-angle lenses made by Canon Inc. The original version, the EF 16-35mm f/2.8L USM, replaced the EF 17-35mm f/2.8L USM lens, which had itself replaced the EF 20-35mm f/2.8L lens.
The EF 50mm lenses are a group of normal prime lenses made by Canon that share the same focal length. These lenses are based on the classic double-Gauss lens, with the f/1.8 being a standard six-element double-Gauss with an air gap and powers between element 2 and 3 and its faster cousins adding additional elements. The 50mm focal length, when used with a 35mm film or full-frame sensor, has been widely considered to match the perspective seen by the human eye.
The EF 35 mm lenses are four wide angle prime lenses with EF mount made by Canon Inc. The family also includes one EF-S lens that only mounts on Canon bodies with APS-C sensors. Due to the 1.6 crop factor of Canon APS-C sensors, all of the 35 mm lenses have a 35 mm equivalent focal length of 56 mm, making them normal lenses on APS-C bodies.
The Canon EF 28–105 mm f/4–5.6 is an inexpensive zoom lens often included as a kit lens with Canon 35 mm single-lens reflex cameras. 28–105 mm is a standard wide to telephoto zoom range.

Some versions of the lens may include the word macro or a flower icon which indicates macro capability, however due to the 1:5.2 image magnification ratio it cannot be considered as a true macro lens.
