Most Minolta lenses for SR-mount cameras are branded Rokkor; in the United States, to combat unofficial gray market imports, lenses officially imported were engraved as Rokkor-X, with the X colored orange. Before 1975, lenses also carried a two-letter suffix indicating the construction.[1]
Because the number of groups is always equal to or less than the number of lens elements, certain combinations are not possible (for instance -QC, which would be a four-group, three-element lens). In other cases, the combination is not used, such as -QG, which would be a four-group, seven-element lens. Although the -OJ suffix was never used for a production lens, a prototype MC Rokkor-OJ 24 mm f/2.8 lens was shown at Photokina 1970.[2]
In addition to Rokkor-branded lenses, Minolta also sold a lower-cost line of lenses, designated Celtic.[3]: 66 Compared to the Rokkor lenses, Celtic lenses have less sophisticated coatings.[4]: 8
In the final series of lenses (after 1981), the "Rokkor" branding was dropped.
Minolta SR-mount lenses can be broken into three broad generations with some overlap:[5]
In general, MD lenses tend to incorporate more plastic components and are lighter than MC and pre-MC lenses. Within each of these generations, there are minor differences which are generally cosmetic changes.
Name | Generation | Years | Example | Notes |
---|---|---|---|---|
Pre-MC | SR | 1958 – 1966 | The earliest lenses had pre-set and manual aperture controls. Lens engraving included "Rokkor" branding, basic construction details, maximum aperture (1:nnn), and focal length (f=nn mm). | |
AR (I) | 1958 – 1960 | These were contemporaneous with the SR lenses, and had automatic diaphragm, as designated by the engraved "Auto Rokkor" (AR) name. | ||
AR (II) | 1961 – 1964 | These are distinguished from the earlier AR (I) lenses by the evenly spaced f-stop engravings. | ||
"Compact" | 1965 – 1967 | Encompassing both AR and SR types; most have 52 mm front filter threads using a black-colored nose, while preceding generations had 55 mm with a chrome nose. | ||
MC | MC (I) | 1966 – 1969 | These lenses have a meter coupling tab on the aperture ring to signal the aperture setting to the body. The aperture ring is colored silver, while prior generations were colored black. | |
MC (II) | 1967 – 1972 | Cosmetically similar to MC (I) with a more deeply scalloped focusing grip knurling. | ||
MC-X | 1972 – 1976 | Rubberized focusing grip with square, truncated pyramid shapes; aperture ring reverts to black. Starting in the mid-1970s, Minolta began adding two to three anti-reflection coating layers[7] to balance color and contrast across the lens lineup.[8] | ||
MC Celtic | 1972 – 1976 | Budget line. Cosmetically similar to MC-X, with a different rubber grip waffle pattern (finely-spaced rectangular) and simplified coatings. The first lens was a 135 mm f/3.5 branded MC Celtic-QD, with a metal focusing ring and silver aperture ring similar to MC (I), and the Minolta name did not appear on the lens.[9][10] | ||
MD | MD (I) | 1977 | Additional tab added to signal the minimum aperture value (largest f-stop number, smallest diaphragm opening) has been set; aperture ring becomes plastic. | |
MD (II) | 1978 – 1980 | Cosmetic update to put focal length before maximum aperture on the front nameplate. | ||
MD Celtic | 1977 – 1980 | Update of MC Celtic, adding MD tab. | ||
MD (III) | 1981 – 1984 | Dropped "Rokkor" branding; sometimes referred to as "Plain MD". Mechanical lock added to aperture ring to secure the aperture ring at minimum value. | ||
MD (IIIa) | 1985 – 1996 | Possibly rebranded lenses built by a third-party manufacturer, lacking features compared to MD (III). |
