Pentax HD D FA 15-30mm F2.8 ED SDM WR

Covering ultra-wide to wide-angle perspectives, this 15-30mm zoom offers a unique option for full-frame K-mount Pentax DSLRs and is also compatible with APS-C models, where it will provide a 23-46mm equivalent focal length range.

Constant f/2.8 maximum aperture maintains consistent performance throughout the zoom range and also contributes to greater selective focus control.

ED glass elements are featured in the lens design and help to control chromatic aberrations and reduce color fringing for increased clarity and color fidelity.

The High Definition (HD) multi-layer coating is utilized to reduce reflections, flare, and ghosting for improved contrast and color in more trying lighting conditions.

Super Protect coating and integrated lens hood help keep the optics safe in the event of accidental impact or when it comes in contact with water or dust.

Supersonic Direct-Drive Motor (SDM) ensures fast, quiet, and smoother autofocus operation.

A rounded nine-blade diaphragm contributes to a pleasing bokeh quality when employing shallow depth of field techniques. It is completely rounded between f/2.8-4 when at 15mm and between f/2.8-5.6 when at 30mm.

A weather-resistant design features eight seals which better permit working in inclement conditions.
