New PENTAX K-m digital SLR camera


HOYA Co. PENTAX announced the launch of the PENTAX K-m digital SLR camera. Designed primarily for beginning digital SLR photographers, this new entry-class model offers simplified, user-friendly operation, and an easy-to-maneuver compact, lightweight body.

The PENTAX K-m was developed as an entry-class digital SLR camera offering simple, straightforward operation, making it possible for first-time digital SLR users and family photographers to enjoy high-quality digital SLR photography with little trouble or confusion.

It features an upgraded version of the PENTAX-original Auto Picture mode, which automatically detects the type of subject or scene, and sets the proper shooting mode for the photographer. It also features a host of advanced features and sophisticated functions - including the innovative in-body Shake Reduction mechanism - to assist the photographer. It also offers a compact, lightweight body, designed by incorporating PENTAX?s advanced downsizing technologies, accumulated over the years of digital SLR development, into different body parts. As a result, the PENTAX K-m assures simple operation and outstanding operability, even for inexperienced first-time digital SLR users.

Along with the PENTAX K-m, PENTAX will also launch two DA L-series interchangeable zoom lenses: the smc PENTAX-DA L 18-55mmF3.5-5.6AL and the smc PENTAX-DA L 50-200mmF4-5.6ED. Designed for exclusive use with PENTAX digital SLR cameras, these DA L-series lenses are designed to be more compact and lightweight than conventional counterparts, without sacrificing any of the exceptional optical performance common to all PENTAX lenses.
