Ricoh Imaging | Pentax FA 645 400mm f/5.6 EDIF Lens

PENTAX's medium-format, manual, autofocusing telephoto lens features a 35mm-equivalent focal length of 315mm. Extra-low Dispersion (ED) elements improve image quality by reducing chromatic aberrations, while multi-coating not only protects but further prevents reflection to reduce ghosting and flare. Easily switch between autofocusing and manual focusing. The Inner Focus (IF) mechanism additionally allows for manual focus operation, improves focusing speed, and lessens lens extension, which gives a closer minimum focus distance. Features a rotating tripod collar with clip, which allows for swift changes between vertical and horizontal configurations.

Extra-low dispersion (ED) glass is used to eliminate chromatic aberration for improved sharpness and contrast

Multi-coatings offer protection and prevent reflections on the inner side of the lens to minimize ghosting and flare. Also helping to prevent flare is the supplied large lens hood

Fast AF/MF switching is also possible, and an internal focusing system enables easy MF operation and improves focusing speed while minimizing lens extension, allowing for a closer minimum focus distance

Rotating tripod collar with clip to enable quick switching between vertical and horizontal orientations

Aperture can be stopped down from the maximum of f/5.6 to a minimum of f/45 via the aperture ring in manual mode. Alternatively, full automatic diaphragm control is available.
