Yeah, that's what I feared.

The lenses look like they are physically identical, even to the camera-mount contacts, so it is possible the camera body cannot tell the difference. 

In practical terms like lens correction, image stabilization, etc. it probably doesn't matter, as they are optically the same design (with the exception of the improved coatings and rounded aperture blades). In my own case I can change the string to reflect the correct version since I know which version I own.

Thanks for checking!

The difference should be in the electronics inside the lens.  This is where the ID is stored.  But unfortunately it seems they didn't see fit to change this for the updated lens.

My lens is not recognized by exiftool
Tamron 100-400mm F/4.5-6.3 Di VC USD

Split and moved this post from another thread, though I'm not sure if this is correct place either as I believe this is a known subject.

From a previous post
Quote from: Phil Harvey on July 25, 2018, 12:32:34 PMWithout the extender, the lens codes for all these lenses are the same:

Canon EF 300mm f/2.8L IS II USM or Tamron Lens
Tamron SP 70-200mm f/2.8 Di VC USD G2 (A025)
Tamron 18-400mm f/3.5-6.3 Di II VC HLD (B028)
Tamron 100-400mm f/4.5-6.3 Di VC USD (A035)
Tamron 70-210mm f/4 Di VC USD (A034)
Tamron 70-210mm f/4 Di VC USD (A034) + 1.4x
Tamron SP 24-70mm f/2.8 Di VC USD G2 (A032)

Unfortunately, exact identification is difficult because of the overlapping focal-length/aperture ranges, but you should be looking at the Composite:LensID tag, not the Canon:LensType tag since the Canon 300mm is ruled out by the focal length (all these 3rd-party lenses "borrow" the LensType number of this Canon lens).
"It didn't work" isn't helpful. What was the exact command used and the output.

this article concerns canon mount lenses is the issue similar with nikon?

Ah, yes.  I missed the Nikon part.  The point I was making was that it was on the list of lens that had the same exact code, but as you point out, that was for Canon.

So this post is in the exact right place for Phil to see

Thanks!  This will appear in ExifTool 12.32 as "HD PENTAX DA* 16-50mm F2.8 ED PLM AW".

I'm pretty sure this is a DA* lens, right?

Hi Phil,

Thank you very much!
Yes, full name for this lens is indeed "HD PENTAX-DA★16-50mmF2.8ED PLM AW"
see http://www.ricoh-imaging.co.jp/english/products/lens/k/standard/hdpentax-da-16-50/
When ExifTool 12.32 is available, I will check if it's recognized.

Kind Regards, Aloys
