這是解說L鏡編號
不知之前有人PO過嗎
內文轉貼一下:
Beside the rear lens element of many (but not all) Canon lenses is a date code (as seen above) in the form of "UR0902". This code is also present on many other Canon products including camera bodies.
The first letter, "U", indicates that the lens was made in Canon's Utsunomiya, Japan factory. Prior to 1986, this letter is moved to the last position of the date code.
U = Utsunomiya, Japan
F = Fukushima, Japan
O = Oita, Japan
The second letter, "R", is a year code that indicates the year of manufacture. Canon increments this letter each year starting with A in 1986 and prior to that, A in 1960 without the leading factory code. Here is a table to make things simple:
A = 1986, 1960
B = 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
* assumption of continuation being made for future years.
The first two numbers, "09", is the month number the lens was manufactured in. Month 02 is February, month 11 = November. The leading zero of the month code is sometimes omitted.
The next two numbers, "02", are meaningless in determining how old a Canon lens is. This is a Canon internal code (that is occasionally omitted).
由上述例如:UW1201
U:代表CANON公司於日本 Utsunomiya 廠生產,目前高品質之鏡頭大多在此生產。
W:代表西元2008年生產的,2009則為X,2010則為Y。
12:代表該年12月生產。
01:為CANON公司內用之生產序號。
這麼說到2012年則為UAXXXX了 |
