Title: Missing support for Tamron lens ID
Post by: philip5 on December 11, 2011, 12:01:51 PM
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.

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.

Hi Philip,

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

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.
