Rokkor
Rokkor was a brand name used for all Chiyoda Kōgaku Seikō and later Minolta lenses between 1940 and 1980, including a few, which were marketed and sold by other companies like Leica. The name was derived from the name of Rokkō (六甲山), a 932 metre (3058') high mountain, which could be seen from the company's glass-making and optics factory at Mukogawa near Osaka, Japan. The company's founder wanted the name to symbolize the high quality in optics. Overview The first lens to carry the Rokkor designation was a 200mm 4.5 lens that came with the hand-holdable aerial camera Chiyoda SK-100 in 1940. After the Rokkor name was dropped and no longer engraved in new lenses after 1980/1981, the Rokkor name resurfaced two times. As was revealed not before 2006, the Rokkor name was still used internally for prototypes of a never released SR-mount '' Minolta MD Apo Tele Rokkor 300mm 2.8'' manual-focus lens in the early 1980s, a lens design, which later saw life as the A-mount ...

AF (Minolta Lens Designation)
Minolta and its successor Konica Minolta released the following lenses for Minolta A-mount cameras between 1985 and 2006. History While most auto-focus lens designs were new developments, some optical constructions were derived from Minolta SR-mount lenses (as indicated). In the United States, the Maxxum system launched in 1985 with twelve lenses: * 24mm 2.8 * 28mm 2.8 * 50mm 1.4 * 50mm 1.7 * 50mm 2.8 Macro * 135mm 2.8 * 300mm 2.8 APO * 28–85mm 3.5–4.5 * 28–135mm 4–4.5 * 35–70mm 4 * 35–105mm 3.5–4.5 * 70–210mm 4 Initially, the lenses were equipped with narrow ribbed manual focus rings in hard plastic near the front; zoom lenses had a diagonally-ribbed rubber grip. Later lenses changed the grip style and added a rubber coating to the focus ring. Some of the original lenses were re-released with updated cosmetics and are known as "New" or "Restyled" versions; minor optical updates such as coatings and aper ...

Minolta SR-mount
The Minolta SR-mount was the bayonet mounting system used in all 35 mm SLR cameras made by Minolta with interchangeable manual focusing lenses. Several iterations of the mounting were produced over the decades, and as a result, the mount itself was sometimes referred to by the name of the corresponding lens generation (f.e. "MC", "MD" or "X-600") instead. All lenses for these mounts are interchangeable between older and newer Minolta manual focus 35 mm film SLR bodies. There are exceptions, such as, the lenses before 1961 feature a slightly different aperture leverage, and thus the automatic diaphragm may not work correctly on post-1961 cameras, and later MC/MD tabs may hit a screw of the front cover on earlier cameras. Four design enhancements, all forwardly inclusive and backwardly compatible, are: # SR - 1958-1966: Plain SR-bayonet featuring automatic diaphragm. Lenses are labelled ''Rokkor'' (pre-set) or '' Auto Rokkor'' (automatic diaphragm) # MC - 1966-1977: Meter coupling a ...
