This is a very compact lens designed for the Pentax K mount crop-sensor SLR camera bodies. The effective focal length becomes 60mm with those systems.
Note that this lens despite being built for crop sensor cameras is apparently useful on full framed Pentax film bodies as well. Boris Liberman has some test shots on his site that show the DA 40mm in action, mounted on his film body. Viginetting for this lens is not as bad as you would expect.
