Popular Photography in its March 2002 issue called the Pentax SMC-FA 31mm Limited one of the greatest prime lenses it had ever tested
Yet all things considered, the 77mm may be the best lens of the three. A nearly ideal short tele, the 77mm Limited is superb — contrasty, excellent for portraits wide open, with a truly beautiful, delicate bokeh that compliments the almost 3-D vividness of the in-focus image. Tops in its class? There are certainly a lot of great short teles out there. But I can't name an AF SLR short tele I'd put above it.
