Founded by Antonio Bencini, in 1937 as I.C.A.F. in Milano (Italy), the company shortly changed its name to C.M.F. After WWII it was renamed again, to CMF Bencini, the name under which it became renowned for its characteristic rigid body cameras. But it made also folding cameras like the Argo rollfilm folder with Aplanatic F:10.5 lens in CMF A3 single-speed shutter.
