The Canon EF 100 mm lenses are used for Canon DSLR cameras. There are four different types of EF 100 mm lens for Canon. Certain lenses are best for macro photos, whereas other lenses are good for taking pictures of subjects from a distance.

EF 100mm f/2.8 Macro lens

The Canon EF 100mm f/2.8 Macro was a prime lens designed for Canon's EF lens mount. It was first marketed in April 1990 with an original price of 72,200 yen.

, which increases the maximum magnification to 1.19× (EF 12 II) or 1.39× (EF 25 II). In these cases, focusing at infinity is sacrificed, with maximum distance reduced to 1002 mm (3.3 ft) and 606 mm (2.0 ft) respectively.

EF 100 mm 2.8L Macro IS USM lens

The EF 100 mm 2.8L Macro IS USM lens is the second macro lens in the Canon L series. It incorporates IS, improved build quality, weather sealing, and a new lens configuration resulting in improved MTF plots. This is the first lens on the market to incorporate Canon's new Hybrid Image Stabilization Technology. Hybrid IS effectively compensates for both angular and shift camera shake during close-up shooting. This lens requires the Macro Lite Adapter 67 to be used with the MR-14EX and MT-24EX macro flashes.Canon EF100mm f/2.8L MACRO IS USM Instruction manual
(The instruction manual says "Macro Lite Adapter 67" but the product is sometimes sold by other vendors as "67C".)

EF 100 mm 2.0 USM lens

The EF 100 mm 2.0 USM lens is a compact medium telephoto lens with a large aperture. Its physical and optical characteristics are similar to the Canon EF 85 mm 1.8 lens. Since this lens is not a macro lens, it is lighter and smaller than the macro lenses. It is also a stop faster. Therefore, it can act as an excellent general-purpose lens. It can be used for candids,

, and other situations where a somewhat narrower field of view compared to the standard 50 mm lens is useful. Its fast maximum aperture lends itself to low-light photography like standard lenses, with excellent performance wide open. The addition of EF Extension Tubes allows close-up and partial macro-like photography using this lens.
