Pentax Ricoh has announced the Pentax DA 18-270mm F3.5-6.3 ED SDM superzoom and a the HD Pentax DA 560mm F5.6 ED super-telephoto prime. The 18-270mm offers a 15x superzoom covering a 27.5-414mm equivalent range and is based around the company's SDM 'supersonic AF' motor. Meanwhile the 560mm F5.6 becomes the first Pentax lens to be given its 'HD' coating which, the company says, denotes high performance. The 859mm equivalent super-telephoto lens is environmentally sealed, to match the performance of the company's higher-end DSLRs. The lenses will cost around $800 and $7,000 respectively.
