HD Pentax-DA* 16-50mm F2.8 ED PLM AW Lens Officially Announced

Ricoh has just officially announced the new HD Pentax-DA* 16-50mm F2.8 ED PLM AW lens. It is a premium wide-angle zoom for the company’s APS-C cameras, featuring ED and anomalous glass elements as well as an HD coating to reduce flare and ghosting,  a “PLM” pulse motor to drive the focus group, the minimum focus distance of 30cm, with a max magnification of 0.24x. The lens is sealed against dust and moisture, much like the company’s DSLRs.

The newly designed optics assures great improvement in contrast and resolving power, while compensating various aberrations to a minimum and delivering sharp, clear images across the image field.
