The Pentax 120mm Macro f/4 645 is a short telephoto that’s as useful for portraits and general purpose photography as it is for macro, providing an equivalent focal length of 96mm when mounted to a medium-format Pentax 645D camera, or 77mm when used on a 645 film camera. Providing a “true” macro magnification factor of 1:1, reproducing subjects at life-size, this lens also allows the user to get as close as 39cm from the subject.

It has been treated with Super Multi Coating, which significantly improves light transmission and ensures faithful colour reproduction, and has a maximum aperture of f/4. Thanks to its sophisticated internal optical construction, the lens is ideally placed to take advantage of the high quality offered by Pentax’s medium format 645 cameras.
