Pentax 90 mm F2.8 HD D-FA ED AW SR 645 Objective

The HD Pentax-D FA 645 90mm ED AW SR Macro is a short telephoto lens designed for use with PENTAX 645 digital cameras where the focal length is ideal for macro and portraiture. Pentax promises a beautiful bokeh (out-of-focus effect) thanks in part to an aperture with 9 rounded blades.

The lens provides up to 0.5x magnification and incorporates two ED (extra-low dispersion) elements and one glass-molded aspherical element in its optics.

The lens covers the full 645 format and can thus be used on 645 film cameras as well as on 645 digital cameras. It has built-in Shake Reduction and is weather-sealed like all other modern medium format lenses from Pentax. It was the first Pentax medium format lens to feature Pentax HD coating, which is superior to the traditional SMC.

The lens has a built-in motor for the autofocus function. On a 645 film camera the lens can be used in manual focus mode only, and only in P and Tv exposure modes due to the lack of an aperture ring.
