I wanted to build an awesome place for people to discuss module specific issues, but I don't have any more time for this, and there are much better places to discuss Perl-related issues. I'd recommend asking your question on Stack Overflow or on Perl Monks.
If you are looking for a Perl tutorial or Perl-related news, I hope these links will serve you well.

Re: New Lens Data ?
Hi Bozi,

Thanks! Robert Rottmerhusen explains why 3rd party manufacturers are changing the LensIDNumber in their lenses:

"The reason why the 3rd party manufacturers are using different ID's now is the focus adjustment feature of newer Nikon pro cameras. This feature uses only the one byte LensID to recognize a lens (again) and this was almost one number in the past with these lenses."

So the reason is to differentiate their lenses for the new focus adjustment feature.
