Reverse Engineering / Lens serial number in Exif
« on: December 16, 2020, 08:22:23 AM »
Canon added lens serial number in Exif 2004 (28-300 f/3.5-5.6). The tag is a mix of decimals and hexadecimals.

Lenses from 2014 from (16-35/4L IS) have the same lens serial number in Exif as written on the lens.
Samples what Canon has used before

Any idea how to convert lens serial number in Exif to the real lens serial number? I have tried some combinations this morning without result.
