Not really a bug report...

Hi Phil,

I just tried exiftool and I am quite impressed. I only want to mention that there is an assumption about a lens that is actually correct. When I run

$ exiftool DSC_3173.JPG | grep -i lens

I get

Lens Type                       : D
Lens                            : 28-300mm f/3.5-6.3
Lens Data Version               : 0203
Lens ID Number                  : 230
Lens F Stops                    : 5.42
Lens ID                         : Unknown (E6 41 3C 8E 2C 40 1C 02) Sigma 28-300mm F3.5-6.3 DG Macro ?
Lens                            : 28-300mm f/3.5-6.3 D

The lens I used is really a "Sigma 28-300mm F3.5-6.3 DG Macro" and no other tool I tried knew anything about it :-) So you can probably skip the "Unknown" string in the next release. (btw.: since the official libimage-exiftool-perl package in debian is version 8.15 I just created a new one from release 8.56, but the result is the same).

Cheers,

Stefan

Hi Stefan,

Cool.  Since Nikon started including the per-lens AF adjustment feature Sigma has been renumbering their lens ID's to be unique.  I still don't know all of the new numbers, but have added the logic to check the other paramters to look for the best match.  Nice to know it actually works.

I'll add your new lens ID to the next release.

Thanks!
