March 2010: HOYA CORPORATION PENTAX Imaging Systems Division is pleased to announce the launch of the PENTAX 645D lens-interchangeable, medium-format digital SLR camera. Thanks to the incorporation of a large image sensor, equal in performance to professional-standard digital camera backs, this high-performance model delivers super-high-resolution images with approximately 40 effective megapixels. It also offers outstanding dependability and superb operability and manoeuvrability to make outdoor shooting effortless and comfortable for demanding photographers.
The PENTAX 645D has been developed to provide super-high-resolution images produced by large image sensors — something previously available only on professional models — to serious landscape and outdoor photographers. It combines exceptional image quality with excellent manoeuvrability and outstanding reliability to simplify professional-level outdoor shooting. Thanks to the incorporation of a large, high-performance image sensor (measuring 44mm by 33mm) and PENTAXoriginal image-processing technology, it produces extra-sharp, super-high-resolution images with approximately 40 effective megapixels. It features remarkable durability and dependability, thanks to its lightweight but solidly built body featuring a magnesium-steel-alloy frame, reinforced glass LCD panel protectors and a reliable dustproof, weather-resistant construction. In addition, it is designed to be compatible with the majority of the existing PENTAX 645 system, so that current PENTAX 645-series camera users can take advantage of their valuable assets, including high-performance SMC PENTAX 645 interchangeable lenses.
