Pentax FA 50mm f/1.4 Overview

A standard lens for Pentax autofocus cameras with a bright f/1.4 aperture.  The SMCP-FA 50mm f/1.4 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/1.4 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 23.5 x 15.7mm 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.
