| PENTAX Delivers Two Digital SDM Zoom Lenses PENTAX Imaging Company has announced a new series of high performance lenses – the smc PENTAX-DA Series (pronounced PENTAX D.A. Star Series). The first two lenses in the series are the smc PENTAX-DA 16-50mm F2.8 ED AL[IF]SDM wide angle zoom and the smc PENTAX-DA* 50-135mm F2.8 ED [IF]SDM telephoto zoom. Previously announced in September 2006, the two interchangeable lenses are designed for exclusive use with PENTAX digital SLR cameras. These PENTAX-DA series lenses feature tightly sealed, weather-resistant and dust-resistant construction to enhance durability for use in rain or dusty conditions making each a perfect companion for the weather-sealed PENTAX K10D digital SLR. The lenses also feature the PENTAX original Quick-Shift Focus System for instant switching to manual-focus operation and PENTAX-original SP (Super Protect) coating to repel dust, water and grease. A new SDM system has been incorporated for smoother, quieter autofocusing operation using a built-in supersonic motor. These lenses feature the PENTAX KAF2 mount, which incorporates additional electrical contacts to drive a built-in supersonic motor used in autofocusing operation. write your comments about the article :: © 2007 Computing News :: home page |
