Ricoh Imaging | Pentax FA 645 120mm f/4 Macro Lens

This medium-format, manual and autofocusing short telephoto and portrait prime lens from PENTAX gives a 35mm equivalent focal length of 96mm, when used with the PENTAX 645D or 77mm with the 645 film camera. This lens features floating and independently-moving aperture mechanisms and was developed with computer-assisted design technology for precision.

Super Multi Coating (SMC) improves light transmission, while Extra-low Dispersion (ED) corrects chromatic aberration to create sharp, high-contrast images across the focusing range. It features a 1:1 magnification ratio, has a f/4 maximum aperture that stops as far as f/32, and focuses as close as 15.4 inches. Use the focus limiter to set a distance range for increasing the autofocus speed.
