Wide and Fast

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

normal-looking wide-angle shots, there are longer wide-angle lenses

up to 35mm with the maximum aperture you need.

EF 15mm f/2.8 Fisheye

A full-frame fisheye lens that's ideal for

special effects with any EOS camera,

film or digital. It focuses as close as

eight inches (0.2m), and is tack-sharp

throughout its focus range. Up to three

gel filters can be inserted into its built-in

rear filter holder.

EF 14mm f/2.8L USM

This is a true rectilinear ultra-wide-angle

lens that's absolutely corrected for

linear distortion — straight lines remain

straight. It's outstanding for shooting

in confined areas and interiors, and is

often used by professionals because of

the unique "look" its extreme wide-

angle perspective provides. The optics

are superb, highlighted by a ground

and polished aspherical element. It

has a gel filter holder in the rear that

allows up to three gel filters to be used

for color correction.

EF 20mm f/2.8 USM

The optical performance, fast f/2.8

speed and ultra-wide-angle coverage

make this a great choice for many

applications, like interiors, scenics,

travel and photojournalism. It uses a

"floating" optical system for excellent

sharpness even at its minimum 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.

EF 24mm f/1.4L USM

That f/1.4 is not a typo — this is the

fastest ultra-wide-angle lens in the

world. The first EF lens to combine

Aspherical and UD Ultra-low Dispersion

glass L-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.
