Pentax Normal SMCP-FA 50mm f/14 Autofocus Lens

A standard lens for Pentax autofocus cameras with a bright f/14 aperture  The SMCP-FA 50mm f/14 is an excellent choice for lowlight handheld photography - and effectively becomes a brilliant short telephoto portrait lens when used upon the ist series of digital SLR cameras  The Pentax Super Multi Coating process provides the highest possible transmission of light If you use the SMCP-FA 50mm f/14 with an ist series digital SLR camera and desire the light-shielding contrast benefits from a lens hood - Pentax's RH-RB49 hood (catalog number 34774 - B&H item code PELH70210AF) provides the most effective shielding  While this hood would cause vignetting with a full-frame 24 x 36mm-type camera(such as a Pentax 35mm SLR) - the smaller 235 x 157mm sensor size of the ist series makes the RH-RB49 an ideal shielding device  In such applications - a 49mm polarizer can be used at the front of the hood with no darkening of the image corners
