I recently bought a new-to-me D3200, which has kick-started an interest in using a DX digital slr. In the meantime I've been using a lovely little Ricoh as my pocket camera. It's the GX100, which has a wide-angle zoom lens, ranging from 24-72mm equivalent. I've been very pleased with the images I've got from the Ricoh and so the first lens I bought to go with the D3200 was the Nikkor DX 12-24mm AFS, which turned up the other day, in lovely condition. I took some images inside my flat to get a feel for the field of view and how it felt on the camera - nice :-) But imagine my surprise when I took a look at the exif data for the first few images and saw that the lens is described as, "Lens Model: Tokina AT-X 124 AF PRO DX II (AF 12-24mm f/4)"

Can anyone tell me what's happening here?

What software do you use to read the EXIF?

The 12-24 was co-developed with Tokina and might use the same hex values to identify, but with a second group to identify the maker.

Hi Merco,

the reference to Tokina shows up in both Apple's Photos version 4 (cmd+i) and Apple's Preview version 10.1 (cmd+i).  It's not a big deal - obviously, the lens is the Nikon model, and not the Tokina, but I'm interested to find out how it was mis-identified by the software.  A case of mistranslation, I guess.

Another thing that's slightly puzzling is that the lens doesn't have an obvious serial number showing anywhere - my other Nikkor lenses have a serial number close to the country of origin - in this case, Japan, but this lens doesn't have a serial number that I can see.

I've notice with Adobe Lightroom that, if you're shooting jpeg, the application will sometimes/often misidentify your lens. This usually shows up in the lens correction panel/ profile corrections tab. That's probably because profile corrections require RAW file information. I'm not sure if Apple software has the same limitations.

You could install the Nikon software and check if ViewNX-i or Capture NX-D does a better job identifying your lens. Preview and Photos probably use the same module for identifying lenses.

 

I don't remember where the serial number is located on the 12-24.

Thanks, folks - it's a lovely lens, not-with-standing its exif data!  ;-)
