The Canon EF-S 60mm f/2.8 Macro USM lens is Canon's only EF-S (APS-C sensor specific) macro lens. Introduced in 2005, it was the first EF-S prime lens, and remained the only EF-S prime lens until the announcement of the EF-S 24mm f/2.8 STM in September 2014. It can only be used on cameras with a 1.6x crop factor and is the equivalent of a 96mm lens mounted on a 35mm format camera. As such this lens also can be a good choice for portrait photography.
Its front element does not rotate, nor does it protrude when focusing. This is especially useful when working with a polarization filter or close to the subject.
