Many EOS shooters consider this two professional lenses in one: a
superior-performance portrait-length tele with a fast f/2.8 aperture and
lightning-quick USM AF; and a superb macro lens that focuses to life
size (1x) without accessories. It has a unique internal focusing design
and floating optics for sharpness throughout its vast focus range, and
allows a working distance of 5.9 inches (149mm) at life size. Full-time
manual focusing and an available Tripod Mount B with adapter round out
this terrific macro lens.
