Hi all,

Just wondering what people generally use for the lens serial number?

Are people putting this in the XMP-aux: LensInfo tag?  If not, where do most people add this information?

Cheers,

JP

The XMP:LensInfo tag is used by Adobe to store 4 rational values giving
the focal range and aperture range of the lens, so this isn't very suitable
for storing the lens serial number.

I'm not aware of what people generally use for this.  If it were me I'd
create a user-defined "LensSerialNumber" tag and add this to the
XMP-aux group.
