Canon EF 100mm lens : ウィキペディア英語版 | Canon EF 100mm lens The Canon EF 100mm lenses are used for Canon DSLR cameras. There are four different types of EF 100mm 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 2.8 Macro USM lens==
The EF 100mm 2.8 Macro USM lens is a prime lens made by Canon Inc. It is of the EF lens mount that fits the EOS camera system. There are three versions, the original, a second that adds a USM autofocus motor, and a recently released L series version that incorporates Image Stabilization (IS). It is a macro lens, meaning that it is capable of reproducing an object the size of the image sensor, known as 1:1 magnification. Despite the macro designation, the lens can focus to infinity like regular lenses. As such, it is appropriate for use as a portrait lens. This lens can be used with an extension tube, which increases the maximum magnification to 1.19x (EF 12 II) or 1.39x (EF 25 II). In these cases, focusing at infinity is sacrificed, with maximum distance reduced to 1002mm (3.3 ft) and 606mm (2.0 ft) respectively.〔Canon Extension Tube EF12 II / EF25 II Instructions〕
