The EF-S 18-135mm f/3.5-5.6 IS Lens from Canon
is a wide-angle to telephoto zoom lens with a
field-of-view of 29-216mm in the 35mm format. It is designed for use
with Canon APS-C EOS Digital SLR cameras. Measuring just 4.0" (10 cm) in
length and weighing about a pound, the lens offers a versatile set of
focal lengths and is sized to be your everyday, use-for-everything lens.
16 elements (including a UD-glass element) in 12 groups, the Canon EF-S
18-135mm f/3.5-5.6 IS lens captures an angle-of-view range of 74.2° to
11.3°, which is wide enough for most interior shots and long enough to
capture distant subjects.
The lens features an internal focusing
system with a minimum focus distance of 1.5' (45 cm), and provides
optical image stabilization for up to 4-stops of compensation against
blur when shooting in low light conditions.
