With a focal length of 70mm, 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, with an overall length of only 1 inch and weight of a mere 4.6 oz. 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, available in both black and silver models
