Pentax SMCP-FA 645 300mm f/4.0 ED IF Lens

This medium-format, manual, autofocusing telephoto prime lens with a 35mm-equivalent focal length of 200mm assists with creating high-contrast, clear images, all while reducing extension when focusing.

PENTAX's Super Multi Coating was added to the surface to create sharp photographs, while Extra-low Dispersion (ED) elements reduce chromatic aberrations to enhance quality. Inner Focus (IF) functionality decreases lens extension during focusing, allowing for improved balance, smoother focus ring operation, and a closer minimum focus distance.

Features a compact f/4.0 aperture and lens developed with computer-assisted optical design technology for a higher degree of precision.
