Medium-format telephoto prime

The Pentax SMCP FA645 200 mm F4 IF is a new medium-format telephoto prime lens designed for Pentax 645 system cameras. It provides a 35 mm-equivalent focal length of 157 mm for long-distance photography. Both manual and autofocus operation are supported for flexible shooting control. The lens includes a protective cap.

Upgrade from shorter focal lengths

This 200 mm focal length replaces shorter medium-format lenses when subject distance requires greater reach. The jump is worth it for photographers needing the 157 mm equivalent perspective for compressed backgrounds. Internal focusing maintains a constant lens length during focus adjustments. SMC and ghostless coatings reduce flare and internal reflections for higher contrast.

Headroom for portraits and detail work

The fast f/4 maximum aperture handles low-light conditions and allows shallow depth of field for subject separation. Two extra-low dispersion glass elements correct chromatic aberration across the frame. The optical design delivers sharp detail and a soft bokeh rendition. It runs out of width for environmental or architectural scenes requiring a broader field of view.

Questions about this item

What camera mount does the Pentax FA 645 200 mm f/4 IF lens use?

It uses the Pentax 645 bayonet mount for medium-format cameras.

How is the lens focused and what step is often missed?

Switch the AF/MF lever on the lens barrel to the desired mode; forgetting to set the camera body to the same mode prevents autofocus from engaging.

What regular care does the lens require over time?

Keep the front and rear elements clean with a blower and microfibre cloth, and store the lens with caps fitted to protect the SMC and ghostless coatings.
