HD Pentax-DA 15mm f4 ED AL Limited lens (Black)
Super wide lens using the latest HD coating and a round iris diaphragm for delineation performance
This super wide lens uses an aspherical lens and extra-low dispersion (ED) glass lens to correct distortion and chromatic aberration for delineation performance. The curvature of the first lens front surface was reduced, and it supports use of a circular polarizing filter. The lens also includes a built-in retractable sliding flower-shaped hood.
