Missing support for Tamron lens ID

[philip5]

Hi

I have the Tamron SP AF 17-50mm F/2,8 XR Di II LD Aspherical [IF] with Nikon mount which isn't supported in exiftool 8.72
on Linux. I recently reported this lens to the exiv2 tool developers too where you also can find an example image with exif data.

Here is what exiftool 8.72 gives:

$ exiftool SBC_0542.NEF | grep -i lens
Lens Type                       : G
Lens                            : 17-50mm f/2.8
Lens Data Version               : 0204
Lens ID Number                  : 251
Lens F Stops                    : 7.00
Lens ID                         : Unknown (FB 54 2B 50 24 24 84 06)
Lens                            : 17-50mm f/2.8 G


More about this with exiv2: http://dev.exiv2.org/issues/791

Hope this lens can get support with exiftool too.

Thanks, I'll add this.  What is the model number of this lens?  I'm guessing A16NII?

How can I find out that? All I see on the lens is a unique serial number. I don't have the original box it come with close.

Thanks, I'll add this.  What is the model number of this lens?  I'm guessing A16NII?

It may not be printed on the lens.  Is it possible to check the box?

Sorry for the delay but I had the box stored away. Had a look at it now and it have a label with "A16N2" on it.

It may not be printed on the lens.  Is it possible to check the box?

Btw, good news. Issue is solved with 8.73.

$ exiftool -ver
8.73

$ exiftool SBC_0538.NEF | grep -i lens
Lens Type                       : G
Lens                            : 17-50mm f/2.8
Lens Data Version               : 0204
Lens ID Number                  : 251
Lens F Stops                    : 7.00
Lens ID                         : Tamron SP AF 17-50mm f/2.8 XR Di II LD Aspherical (IF) (A16NII)
Lens                            : 17-50mm f/2.8 G

Thanks!

Hi Philip,

Thanks for the confirmation.  I'll change the model to A16N2 for the next release (you just missed this one).

- Phil

Edit: After more research it seems that the same lens is sold in different markets with different model numbers, and A16N2 and A16NII are the same lens.  So I will leave the model number as A16NII in the lookup.
