NEW EF LENSES

The EF24-70mm f/2.8L II USM is a high-performance L-series large-aperture

standard zoom lens with a wide focal length that uses three aspheric lens

elements, one Super UD lens element, and two UD lens elements. This

accurately corrects magniﬁcation-type chromatic aberration at wider angles

to achieve incredibly pure image quality.

Now in a more compact form, this highly durable and tough lens is fully

capable of weathering harsh conditions and frequent usage. Besides quick

yet silent autofocus, the EF24-70mm also has a mechanical manual focus and

a circular aperture for beautiful soft-focus images. With minimum focusing

distance of 0.38 meters and magniﬁcation of 0.21x, this lens is also perfect

for close-ups.

EF 24-70mm f/2.8L II USMEF 24mm f/2.8 IS USM & EF 28mm f/2.8 IS USM

Introducing two of the ﬁrst wide-angle single-focus lenses to possess a built-in

image stabilizer — the EF24mm f/2.8 IS USM and the EF28mm f/2.8 IS USM.

This new image stabilizer feature achieves the equivalent effect of up to four

stops faster.

With a ring ultrasonic motor (USM) and optimized autofocus algorithms

for responsive and quiet auto-focusing, these small and lightweight lenses

are a breeze to operate. The EF24mm f/2.8 IS USM has a shorter minimum

focusing distance of 0.2 meters compared to its former model while the

EF28mm f/2.8 IS USM features a shorter minimum focusing distance of 0.23

meters, thus allowing photographers to get closer to the subject.
