● Special-edition Custom Images

To make photographic experiences with PENTAX digital SLR cameras even more enjoyable and exciting, PENTAX is providing a new approach to SLR photography, through special-edition Custom Images designed to create subject- or scene-specific finishing touches in combination with certain PENTAX Limited-series lenses — lenses popular for their distinctive image rendition. PENTAX will release a series of season-specific Custom Images to create distinctive finishing touches dedicated to the spring, summer, autumn and winter seasons. As a lens is mounted, the camera automatically detects compatibility with the firmware. Once compatibility is confirmed, the user can then select special-edition Custom Images.

● KATEN (summer sky)

This special-edition, season-specific Custom Image mode is designed to emphasize the rich blues of summer skies and depict the fine details of dazzling white clouds. This mode can be selected in combination with HD PENTAX-D FA 21mmF2.4ED Limited DC WR and HD PENTAX-DA 15mmF4ED AL Limited lenses. Both lenses feature an ultra-wide angle of view and the latest HD (High Definition) coating, which effectively minimizes the generation of ghost images even with images captured under harsh summertime sunshine, or when the sun is in the image field. They have been selected as the best partners for the KATEN mode because they optimize the intended visual effects of the mode.

● Upcoming schedule

Following on the KATEN mode, PENTAX will release specific-edition, season-specific Custom Images specially designed for SLR photography in autumn, winter and spring. Check the chart below for detailed information.
