AF LENSES for Canon, Nikon, Sony/Minolta, Pentax & Sigma
ULTRA-WIDE ANGLE ZOOM LENSES
10-20mm f4-5.6 EX DC HSM
This ultra-wide zoom lens has a wide angle of view from 102.4 - 63.8° (when Sigma mount is used) and it
is exclusive to digital SLR cameras. SLD glass elements effectively compensate color aberration. Aspherical
lenses provide maximum correction for distortion and various aberrations; high image quality is displayed
throughout the entire zoom range. HSM-equipped it makes fast AF speed and quiet shooting a reality, and
it is also capable of full-time manual focus. Minimum focusing distance of 9.4˝at all focal lengths. Has an
integrated Petal-type hood to block out extraneous light. Filter size is 77mm.
15-30mm f3.5-4.5 EX DG Aspherical
This rectilinear lens has a minimum focusing distance of 11.8˝ at all focal lengths. Ideal for images
of landscapes, large buildings, group photographs or even more. A hybrid aspherical lens in the
front lens group minimizes distortion and astigmatism, while molded glass aspherical lens in the
rear group minimizes spherical aberration. 8-blade diaphragm achieves beautiful out of focus
images in the foreground and background. Dual focus mechanism and inner focusing system
makes it easy to hold. Includes non-removable “Perfect-Hood” and uses rear gelatin filters. Used
on most digital SLR cameras, the effective zoom will be 22.5-45mm. Super Multi Coating reduces
flare and ghosting that tends to occur when using digital SLR cameras. Includes a padded case.

17-35mm f2.8-4 EX DG Aspherical HSM
The 17-35mm lens covers a super wide-angle range and has improved closer focusing over it’s
predecessor. It is equipped with the inner focusing system that will keep the length of the lens
unchanged while controlling aberration. The models which are equipped with HSM system
(available for Sigma, Canon and Nikon) offer full time manual focusing. SLD (Special Low
Dispersion) glass is used for effective compensation of color aberration. Accepts a Petal-type hood
and it is easy to use a circular polarizing filter. Filter size: 77mm.

12-24mm f4.5-5.6 EX DG Aspherical HSM
This lens has a large angle of view (122° at 12mm) making it ideal for shooting indoors as well as outdoor
landscape photography. It has a variable angle of view from 122° to 84.1°, and is equipped with four
Special Low Dispersion (SLD) glass elements for effective compensation of color aberration which is a
common problem with super wide-angle lenses. Three pieces of aspherical lenses offer excellent correction
for distortion as well as all types of aberration for a high level of optical performance. Inner focusing system
ensures the length of the lens remains unchanged while controlling aberration. By effective arrangement
of lens elements and advanced technology the lens has super compact dimensions of 100mm full-length,
and 87mm maximum diameter. Minimum focusing distance of 28˝ at all focal lengths. The lens is
equipped with an integral petal-type hood to block out extraneous light. Rear gelatin filter slot.
