Pentax HD PENTAX-D FA 15-30mm f/2.8 ED SDM WR Lens

The HD PENTAX-D FA 15-30mm f/2.8 ED SDM WR Lens, designed specifically for full-frame cameras, is a specialized ultra-wide angle zoom lens that provides a constant f/2.8 aperture. This feature allows photographers to achieve remarkable control over depth of field and enhances performance in low-light environments. The lens incorporates ED glass elements to minimize optical aberrations and is equipped with an HD multi-layer coating to reduce flare and ghosting effects. Autofocus operation is swift, thanks to the Supersonic Direct-Drive Motor (SDM), and it includes a Quick-Shift focus system for seamless transitions between auto and manual focus. Furthermore, it can focus as close as 11 inches, adding to its versatility.

To ensure peak performance with Pentax DSLRs, this lens is designed to be fully dust- and weather-resistant, featuring eight seals to prevent the ingress of moisture and dust. The bulbous front element is protected by a Super Protect coating, and an integrated lens hood is included to minimize potential damage from accidental impacts. Additionally, the lens boasts a 9-bladed rounded diaphragm, which contributes to the creation of aesthetically pleasing out-of-focus areas.

• 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.
