The PENTAX K-50 boasts outstanding basic specifications that rival many higher priced models, including high-speed continuous shooting at approximately six images per second, super-high-sensitivity shooting at ISO 51200, and high-precision AF with accurate tracking of moving subjects. The K-50 also features a weather-resistant, dustproof construction to assure solid performance under demanding outdoor conditions. It even provides a wide range of advanced shooting features, such as full HD movie recording and a selection of creative tools such as digital filters, to accommodate various shooting requirements. In addition to the standard lithium-ion battery the K-50 can be powered by easy-to-obtain AA-size batteries. The K-50 is available in 120 different colour variations. The colour-to-order service has been extremely popular as a unique, stylish way for PENTAX camera users to express their own style in the choice of their camera system.
