Bob Atkins was nice enough to put together a bit of info on how to decode Canon date codes.
However, I almost ran out of fingers and toes trying to count to 'S' so I threw together the following calculator based on Bob's wisdom. I only know the factory codes that where listed by Bob, if you know any please send them in and I will update the calculator. Also, if you have any tips on finding the date codes please send that in as well. Thanks! eyekode@yahoo.com
