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.
