  • Long to Super telephoto with zoom ratio of 5.5 times
  • New HD (High Definition) Coating
  • Weather Resistant
  • Portraits, sports, events and wildlife

With a zoom ratio of approximately 5.5 times, the 55-300mm range covers a wide variety of telephoto focal lengths, perfect for any enthusiast looking for a long, highly versatile second lens. Complete with the PENTAX HD coating, this lens is capable to capture expressive portraits, fast action sports, music events, and wildlife, in any weather condition.

  • With its zoom coverage of approximately 5.5 times, the lens offers focal-length coverage from 84.5 medium telephoto to 460mm super telephoto (in the 35mm format), making it ideal for use with a wide variety of subjects and applications including portraits, sports, events and wildlife. It incorporates two ED (Extra-low Dispersion) glass elements in its optics to effectively compensate for chromatic aberrations over the entire zoom range and deliver well-defined, true-to-life images.

  • The lens features weather-resistant construction to prevent the intrusion of water and moisture into the lens barrel. When the lens is mounted on a PENTAX weather-resistant digital SLR camera body, the user is assured of greater durability and reliability when shooting in rain or mist, as well as at locations subject to a spray or splash.

  • The PENTAX-original SP (Super Protect) coating repels dust, water and grease to keep your lens clean and your image quality at its peak.

  • Treated with HD coating, a PENTAX-exclusive multi-layer lens coating, enjoy higher light transmittance and lower reflectance than conventional multi-layer coatings. This means it produces sharp, clear images free of flare and ghost images, even under such adverse lighting conditions as backlight.

  • The PENTAX-original Quick-Shift Focus System allows instant switching from autofocus to manual focus operation.
