Features / Specifications

76.5mm to 306mm 4x zoom in 35mm film format Can be combined with the DA 18-55mm standard zoom lens (equivalent to 27.5mm to 84mm in 35mm film format) to cover virtually all shooting ranges with only two interchangeable lenses.
Revolutionary design that is compact and lightweight
Telephoto equivalent to 300mm with 4x zoom in an unbelievably compact, lightweight size. Allows comfortable handling without an imposing appearance that could intimidate subjects when shooting portraits.
High-performance optical system using ED glass
The optical system uses extra-low dispersion (ED) glass to enable efficient correction of various types of aberration for delivering crystal-clear sharp images.
DA lens specifically for PENTAX digital SLR cameras
The design has an image circle matching the 23.5mm × 15.7mm CCD size. It features a simple lens design without an aperture ring.
New AF/MF switching mechanism
Quick-Shift Focus System for AF/MF switching is employed. After focusing by AF, immediately switches to MF if the focus ring is turned. This enables smooth focusing operation without the need for a switching action.
