The black HD Pentax DA 40mm f/2.8 Limited Lens from Pentax is a pancake-style prime normal-length lens providing a 35mm-equivalent focal length of 60mm. The standard 39° angle of view is well-suited to everyday situations and the slim profile is ideal for an inconspicuous shooting style. A high-grade multi-layer HD coating has been applied to lens elements to help minimize flare and ghosting for enhanced contrast, clarity, and color fidelity and a seven-blade diaphragm contributes to an aesthetic out-of-focus quality to benefit shallow depth of field imagery.
