Designed to produce powerful telephoto images, the smc PENTAX-DA* 300mm F4 ED[IF] SDM is a uni-focal super-telephoto lens with a focal length equivalent to 460mm in the 35mm format. It minimizes chromatic aberrations by incorporating ED (Extra-low Dispersion) optical elements in its second and fifth lens. It also offers a minimum focusing distance of 1.4 m (4.6ft), which is the shortest in its product category. Featuring advanced technologies, such as special optical glass elements and PENTAX-original lens coatings, it is designed to assure exceptional optical performance and deliver clear, high-contrast images, even at image-field edges.
