Bug #965
Pentax K-3 MakerNote not recognized due to different maker tag
100%
Description
The MakerNote tag in Pentax K-3 raw files (maybe other recent Pentax cameras), both DNG and PEF, is not recognized by Exiv2 because the Make tag says "RICOH IMAGING COMPANY, LTD." instead of "PENTAX Corporation". If I change the Make tag to anything that says PENTAX, the MakerNote is recognized, but this might break other metadata readers.

The K-3 and 645Z have make "RICOH IMAGING COMPANY, LTD.".
The M-1, WG-3 and WG-10 have make "PENTAX RICOH IMAGING".
All use the same format maker notes that start with "PENTAX \0", so this is the better thing to key on.

So at least a short term fix seems rather trivial, please see attached patch.

Note: I did actually test the above patch with a K-3 PEF and DNG.

Hi Pascal.
Thanks for the patch. I have commited it to the svn trunk.
Beware that this will have to be changed if makernote support for older Ricoh cameras is added to Exiv2.
Best regards,
