Canon Lens Codes
On the back of Canon lenses is a six-digit code, which indicates where the lens was manufactured and when.
Example of a code "UV1212"
The first letter 'U' represents the factory that made the lens. Three possible first letters are:
- U = Utsunomiya
- F = Fukushima
- O = Ōita
The second letter 'V' represent the year of manufacture
- A = 2012, 1986, 1960
- B = 2013, 1987, 1961
- C = 1988, 1962
- D = 1989, 1963
- E = 1990, 1964
- F = 1991, 1965
- G = 1992, 1966
- H = 1993, 1967
- I = 1994, 1968
- J = 1995, 1969
- K = 1996, 1970
- L = 1997, 1971
- M = 1998, 1972
- N = 1999, 1973
- O = 2000, 1974
- P = 2001, 1975
- Q = 2002, 1976
- R = 2003, 1977
- S = 2004, 1978
- T = 2005, 1979
- U = 2006, 1980
- V = 2007, 1981
- W = 2008, 1982
- X = 2009, 1983
- Y = 2010, 1984
- Z = 2011, 1985
The next two digits represent the month of the lens is manufactured.
The last two digits are for internal Canon use.
Therefore the example (pictured) of UV0512 means the lens was made in the Utsunomiya, Japan factory in May 2007.

Famous quotes containing the words canon and/or codes:
“O! that this too too solid flesh would melt,
Thaw and resolve itself into a dew;
Or that the Everlasting had not fix’d
His canon ‘gainst self-slaughter! O God! O God!
How weary, stale, flat, and unprofitable
Seem to me all the uses of this world.
Fie on’t! O fie! ‘tis an unweeded garden,
That grows to seed;”
—William Shakespeare (1564–1616)
“We must trust infinitely to the beneficent necessity which shines through all laws. Human nature expresses itself in them as characteristically as in statues, or songs, or railroads, and an abstract of the codes of nations would be an abstract of the common conscience.”
—Ralph Waldo Emerson (1803–1882)
