MS-Optics (formerly known as MS-Optical R&D) is a small lens manufactory from Japan established in 2006. The “MS” in MS-Optics stands for Miyazaki Sadayasu (born in 1940), CEO of the company and designer of all these lenses.  This 73mm 1.5 is very small and lightweight, yet surprisingly sharp at f/1.5 where it matters and good enough for landscape shooting stopped down.  Bokeh is generally nice too, but a bit unsightly at f/1.5 with defocused light points in the background and unfortunately the amount of longitudinal CA is really high.
