The 10 to 20 millimeters f4 to
5.6 EX DC HSM lens allows
enjoyment of super wide-angle
photography and it is a very
powerful tool for indoor
shooting and landscape
photography with APS-C size
image sensors of digital SLR
cameras.
Wide angle of view (102.4
degrees at 10 millimeters and
63.8 degrees at 20 millimeters)
offers the photographer greater
freedom of expression.
Three SLD glass elements are
employed for effective
compensation of color
aberration, which is a common
problem with super-wide angle
lenses. One piece of glass mold
and two hybrid aspherical
lenses, offer excellent
correction for distortion, as
well as all types of aberration.
This lens is equipped with an
inner focusing system, and the
models which are equipped with
HSM system provide quiet, high
speed autofocus shooting and
also offer full time manual
focusing. It has a minimum
focusing distance of 24
centimeters (9.4 inches) at all
focal lengths. The non-rotating
lens barrel perfectly suits the
petal shaped lens hood. A
circular polarizing filter can
also be used conveniently.
- It covers a superwide angle
of view 102.4 to 63.8
degrees
- Three pieces of Special Low
Dispersion (SLD) elements
and three aspherical lens
elements produce top quality
optical performance.
- Inner focusing system
ensures the length of the
lens remains unchanged
whilst controlling
aberrations.
- Equipped with HSM (Hyper
Sonic Motor) system
- Minimum focusing distance of
24 centimeters (9.4 inches)
at all focal lengths
- Relatively compact,
lightweight for an ultra
wide-angle zoom lens
