Pentax SMCP-FA 31mm f/1.8 AL Limited Wide Angle Autofocus Lens (Black)
The Pentax 31mm f/1.8 FA Limited wideangle lens is a high performance fast optic for discriminating Pentax shooters. Fit and finish are on par with the world's best, and the nine-bladed aperture diaphragm renders unfocused highlights in a smooth, creamy pallette of blurred color. The depth of field scale is as usable as a classic's, and you cannot lose the permanently mounted lenshood.
