Pentax release 100mm F2.8 WR MACRO weather-resistant lens

PENTAX-100mm-F2.8-WR-MACROPENTAX Imaging Company has announced the smc PENTAX D FA MACRO 100mm F2.8 WR lens designed for use with PENTAX digital SLR cameras. Combining a high-quality exterior finish with PENTAX-original weather-resistant construction, this new macro lens is especially useful for the demands of outdoor photography.

This PENTAX macro lens features a high-grade, aluminum barrel with the high-quality, exclusive exterior design and finish unique to the PENTAX D FA series lenses. Further, the entire mechanism of the focus ring has been reviewed and upgraded to assure flawless manual-focus operation. For improved performance, the PENTAX D FA MACRO 100mm F2.8 WR is the first PENTAX interchangeable macro lens featuring a completely rounded diaphragm blade to create a natural, beautiful bokeh at wide apertures, while minimizing the streaking effect of point light sources.

PENTAX WR lenses feature simplified weather-resistant construction to repel water and moisture. Combined with a PENTAX weather-resistant K-7, K20D, K200D or K10D digital SLR camera body, the lens performs well in damp, inclement outdoor conditions including rain, mist, water spray and splashes.

The lens also features the PENTAX-original SP (Super Protect) surface coating to repel dust, water and grease and to minimize fingerprints.

Other significant features of this latest WR lens include:

  • Mounted on a PENTAX digital SLR camera body, this lens offers a focal length equivalent to 153mm in the 35mm format for high-quality, true-to-life images, while minimizing flare and ghost images. The maximum life-size magnification allows photographers to capture dramatic close-up images with great ease.
  • A working distance of just over five inches (13 cm) facilitates close-up photography of subjects including flora, insects, and wildlife.
  • The PENTAX-developed Quick-Shift Focus System for instant switching to manual-focus operation after the subject is captured in focus by the camera’s AF system.
  • An image circle to accommodate 35mm film-format camera image size.
  • Compatibility with the macro adapter included in the PENTAX AF160FC dedicated Auto Macro Ring Flash.

The PENTAX D FA MACRO 100mm F2.8 WR lens will ship in January 2010 for USD $849.95.
