FEATURES- EF 50mm f/2.5 Compact Macro Lens
A superior-performance lens offering excellent optics and focusing
from infinity down to one-half life size (0.5x). Its nine-element
design features a floating optical system, which ensures top-notch
performance even at close focusing distances. Light and compact, it
functions beautifully as a general-purpose normal lens. The
optional accessory Life Size Converter EF enables focusing down to
life size (1:1), and actually increases working distance - very
desireable in close-up shooting.
