Conventional lenses are optimized for focus at infinity not close-up but true macro lenses are corrected for close focus and can be used at infinity. Canon’s EF-S 60mm f/2.8 Macro USM has a floating optical system that lets you focus to life-size (1:1) magnification at a working distance of 4-inches allowing you to fill the frame with a subject the size of a penny. The EF-S 60mm f/2.8 Macro USM is the shortest focal length macro lens Canon offers with internal focusing. AF is driven by a silent ring-type Ultrasonic Motor so the lens’s length doesn’t change when focusing.
Like other EF-S series lenses, the 60mm f/2.8 Macro has a rubber ring surrounding the rear element. That ring sets deeper into the camera than an EF lens and will hit the camera’s mirror if you try to mount an EF-S lens on Canon’s other SLRs. The lens uses special coatings to minimize reflections and flare and has a circular aperture design, so even when stopped down it produces natural-looking bokeh.
When mounted on my EOS 50D, which has 9-point AF system arranged in a wide diamond-shaped array, the most accurate focusing were achieved using the camera’s multi-controller to select a specific focus point, which should be true for other EOS bodies as well. The EF-S 60mm f/2.8 Macro USM is a useful multipurpose lens that’s equally at home capturing macro images or even making portraits and would make a nice stocking stuffer for your favorite Canon-shooting photographer or yourself.
