Canon lens production date codeCanon lens production date code has the following identification methods:
1. Early Canon lenses had a line of white (or gilded) symbols above the rear contacts to represent the lens number. The number similar to U1140F in the film compartment on the back of the camera could also be used to determine. Among them, the first character represented the production date of the camera: 1980, arranged in alphabetic order, A = 1960, B = 1961, T = 1979, U = 1980, until Z = 1985. The last two digits represented the month (sometimes omitting 0 and using a single digit). The following number was Canon's internal factory number, and the last letter represented the place of manufacture (such as F for Fuzhou).
2. The machines produced after 1986 were rearranged from the letter A. The first place became the place of production, and the second place was the date of production (A = 86, B = 87, C = 88, D = 89, E = 90, F = 91, G = 92, H = 93, I = 94, J).
3. For Canon lenses with a 10-digit serial number, the first digit in the body code was the year of production. If the camera was produced in the year of release, the first digit of the serial number would be 0, the second year would be 1, the third year would be 2, and so on. The second, third, and fourth digits of the code were the production batches. According to the production batch code (which may be repeated or different), the batch date could be found by comparing it with the batch code kept by Canon (which may be in a certain month or a certain period of months). The digits after the fifth digit of the code were the serial code of the body. One code for one machine, there was no repetition. According to the serial code of the body, the production date could be found by comparing it with the serial code kept by Canon.

The difference between literary production and literary creation?Literature production and literature creation were two different concepts.
The production of literature referred to the production, production, processing, and distribution of literary works, including the conception, writing, editing, proofreading, publishing, and distribution of literary works. The purpose of literary production was to create and spread literary works to meet the needs and preferences of readers and promote the development and prosperity of literature.
Literature creation referred to the process of creating works with certain aesthetic value, ideology, and artistic value through the use of language and words. The core of literary creation is the creation idea and the creation purpose, and the use of language and words is only a means to achieve the creation idea and purpose.
Therefore, there was a fundamental difference between literary production and literary creation. Literature production is the integration of all the links and processes of literary creation, while literary creation refers to the use of language and words to create works with certain aesthetic value, ideology and artistic value.
