Designed exclusively for Pentax digital SLR cameras, the ultra-
wide-angle 10-20mm offers a view from 102.4 to 63.8 degrees, making it ideal
for landscape photography and other vast applications. The lens is
distinguished by its three special low dispersion (SLD) glass elements, which
effectively compensate for color aberration, and its aspherical lenses, which
provide maximum correction for distortion and various aberrations. As a
result, the lens produces an extremely high image quality throughout the
entire zoom range. Other details include a minimum focusing distance of 9.4
inches at all focal lengths and an integral petal-type hood to block out
extraneous light. Lens Elements and Coating The new multilayer lens coating
and lens design reduce flare and ghost--a common problem with digital cameras
--while also creating an optimal color balance throughout the entire zoom
range. At the same time, the lens offers three SLD glass elements that
effectively compensate for color aberration, along with a piece of glass mold
and two hybrid aspherical lenses that offer excellent correction for
distortion and all types of aberration. Inner Focusing System The lens
incorporates an internal focusing system that eliminates front lens rotation,
letting you use a petal-type hood to protect from additional glare. Best
Consumer Lens The Sigma 10-20mm lens is so respected that it was named the
best consumer lens in Europe (2006) by the Technical Image Press Association
(TIPA), a collection of 31 publications from 12 countries. According to TIPA,
the 10-20mm lens offers a versatile range of wide-angle focal lengths, a good
optical performance, and a budget price, making it an excellent investment for
owners of DSLRs with APS-C format sensors. Its sharpness remains constant
throughout the zoom range, and its compact size makes it an ideal companion
for shooting travel, landscapes, or architectural subjects. Lens construction:
