Capture Distant Subjects with Clarity

The Pentax SMC-FA 645 150mm f/2.8 IF Lens is designed for medium format cameras, providing both manual and autofocus capabilities in a telephoto lens. Its 35mm-equivalent focal length of 118mm, coupled with a bright f/2.8 aperture, excels in low-light conditions and offers a shallow depth of field for stunning bokeh effects. The lens incorporates high-refraction and extra-low dispersion glass to minimize chromatic aberrations, ensuring sharp, high-contrast imagery. Additionally, the Super Multi Coating enhances sharpness and contrast. Its inner focus system minimizes lens extension during focusing, allowing for closer minimum focus distances. A large hood with a PL filter operation window is included for convenient use of circular polarizing filters.
