With a focal length of 70 mm, this medium telephoto lens is a multi-talented masterpiece that gets the most out of portraits and grandiose landscapes from a highly portable lens. This lens produces unusually sharp, high-contrast imagery, and its extraordinarily efficient optical glass is the key to its compact design. It is also equipped with "quick shift" focus system for fast manual focusing in the AF mode, and its unique design incorporates high-grade aluminum construction with treatments of both SP (Super Protect) and the Penatx-original high-grade multi-layer HD (High Definition) coating.
