When sold with a Leitz Minolta CL, the lenses were called "Minolta M-Rokkor 40mm f:2" (later just "Minolta M-Rokkor 40mm f:2") and "Minolta M-Rokkor 90mm f:4". It is said that the 40mm was made in Japan by Minolta while the 90mm was made by Leitz and is rare. With the later Minolta CLE, Minolta would produce lenses of the same name but with a different coupling system, the same as the Leica M lenses. A new "Minolta M-Rokkor 28mm f:2.8" lens was introduced as well. All these lenses can be mounted on the CL too. Rokkor-branded lenses for the CL and CLE take the more easily found 40.5mm filter size.
