Norita

Norita(ノリタ光学,Norita kōgaku) was a Japanese optical manufacturer. Founded in 1951 by Toshio Norita (車田利夫), it originally made lenses for binoculars but moved on to prisms and thence pentaprisms for SLR cameras.

Musashino Kōki (武蔵野光幾) had been making a 6×6 SLR called the Rittreck 6×6 from 1968; for which Norita had been making the pentaprism finder and the three lenses (wide, standard, and tele). When Musashino decided to terminate production of this camera, Norita decided to expand from being merely an optical designer/manufacturer to manufacturing cameras, and took over machine tools, assembly, and some staff from Musashino.
