travel and photojournalism. It uses a
“floating” optical system for excellent
sharpness even at itsminimum focusing
distance of under 10 inches (0.25m),
and with a ring-type USM and full-time
manual focusing capability, offers the
speed and handling pros expect.

fastest ultra-wide-angle lens in the
world. The firstEF lens to combine
Aspherical and UD Ultra-low Dispersion
glassL-series optical technologies, the
24mm f/1.4L provides outstanding
sharpness and contrast even wide open.
It focuses down to 10 inches/0.25m,
and the AF is what you’d expect from a
professional Canon lens with USM—fast
and silent, with smooth full-time
manual focus available at any time.

If you need an ultra-wide angle and a large aperture, one of the
following lenses will fit the bill. Ultra-wide-angle lenses can capture
scenes beyond your natural field of vision. The EF 15mm f/2.8
Fisheye, the widest of them all, has a 180˚ angle of view. For more

up to 35mm with the maximum aperture you need.
