New Pentax Digital SDM Zoom Lenses
PENTAX Imaging Company has announced the first two lenses in the new SMC PENTAX-DA* Series (pronounced PENTAX D.A. STAR SERIES). 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 feature a tightly sealed, weather-resistant and dust-resistant construction making both a perfect companion for the weather-sealed PENTAX K10D digital SLR.
Both lenses use the PENTAX KAF2 mount, which incorporates additional electrical contacts to drive a built-in supersonic motor used in autofocusing operation. A new SDM system has been incorporated for smoother, quieter autofocusing operation using a built-in supersonic motor. The focus mode is automatically switched to SDM-assisted autofocusing when the lens is mounted on the PENTAX K10D digital SLR camera body1. When mounted on other PENTAX digital SLR camera bodies, the conventional autofocus mode (camera-mounted motor) is selected.
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.
