Excellent for Portraiture. When mounted to an APS-C DSLR, the Pentax SMC FA 77mm f/1.8 Limited has a 35mm-equivalent focal length of 115mm, making it a perfect portrait-length lens.

High-Quality Construction. As one of Pentax’s Limited-series lenses, it offers a high-quality metal build, complete with manual aperture ring and focus distance scale.
