Pentax Introduces 17-70mm Standard Zoom Lens

PENTAX smc DA 17-70mmF4AL[IF] SDM Standard Zoom Lens

The new smc PENTAX-DA 17-70mmF4AL[IF] SDM is a standard zoom lens offering 4.1x zoom, covering the most frequently used focal lengths between wide-angle and telephoto ranges. When mounted on a PENTAX digital SLR camera body, this zoom lens covers the equivalent focal-length range from 26mm wide angle to 107mm telephoto in the 35mm format.

This lens incorporates the PENTAX-original SDM system driven by a built-in supersonic motor, which boasts exceptionally smooth, quiet autofocusing operation.

Since this zoom lens offers a maximum aperture of F4 over the entire zoom range, it lets the photographer use higher shutter speeds to minimize annoying camera shake — especially in telephoto applications — or reduce the depth of field to intentionally throw the background out of focus.

The Pentax DA 17-70mm F4 AL [IF] SDM is compatible with the K20D, K200D, K100D Super and K10D (with Ver. 1.30 or later firmware installed) camera bodies. When mounted on other camera bodies, the focus mode is automatically switched to manual.
