Super telephoto lens equivalent to 460mm in the 35mm film format.
Designed to produce powerful telephoto images, the smc PENTAX-D★ 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). 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.
Ultrasonic motor is used in the lens for providing an "SDM" mechanism that enables quiet and smooth autofocus operation. (AF driven by the internal camera motor is also supported.)
The lens components are sealed for enabling a dust-resistant and drip-proof construction that prevents the entry of water and dust into the lens. An inner focus optical system is used for correcting various types of aberrations over the entire shooting range.
SP (super protect) coating for protecting the lens front surface from water and dirt, Quick-Shift Focus System for enabling manual focus operation after focusing by AF without any switching operation.
