I have downloaded the program today and am using it to copy the lens information from Makernotes to the lens model filed in the EXIF. It works perfectly. A minor problem I am facing is with the lens name. I use smc-FA 28-200mm F3.8-5.6 AL[IF] lens. But when the import is done the lens name is converted to  Pentax smc PENTAX-FA 28-200mm F3.8-5.6 AL[IF] or Tamron AF LD 28-200mm F3.8-5.6 [IF] Aspherical (171D). I would like to cut the Tamron part out. Is there any way I can change the lens type to just include the Pentax name? I would like to make this change permanent so that every time I use the Pentax lens the lens model is correct.

I assume you are setting LensModel from the value of LensType?  If so, try this:

exiftool "-lensmodel<${lenstype;s/^Pentax //;s/^Tamron //}" DIR

- Phil
...where DIR is the name of a directory/folder containing the images.  On Mac/Linux/PowerShell, use single quotes (') instead of double quotes (") around arguments containing a dollar sign ($).

Hi Phil

Thanks for the quick response. I tried it. The files do get modified as I see a backup with the extension .original for all the DNG files in the directory. There is no change in the original and the modified file sizes. Here's what I did:

01. Copied the exiftool to the directory.
02. Opened a command prompt in the directory.
03. Used the command exiftool "-lensmodel<${lenstype;s/^Pentax //;s/^Tamron //}" .
04. I get the prompt
   1 directories scanned
   31 image files updated, but nothing happens.
05. Please note that I had already changed the lens model using the exiftool. Shouldn't the command overwrite the lens model in all the files?

Do let me know if I am doing anything wrong.

You can add the -v2 option to see more details about what ExifTool is writing.

Did that. Following is the output of the command for the first few files:

Ah, sorry.  I misunderstood what you wanted.

Try this:

exiftool "-lensmodel<${lenstype;s/ or .*//}" DIR

This should remove everything from " or " onwards.

But maybe this is better:

exiftool "-lensmodel<lensid" DIR

since it should better identify the specific lens.

However the second command exiftool "-lensmodel<lensid" DIR does not work as shown by the output. Though, the first command is good enough for my purpose, curious to know why the second command does not work.

The LensID tag is designed to be ExifTool's best guess at the specific lens model used, but under some circumstances it is not possible to uniquely identify the lens, and in these cases the LensID may still contain " or <some other lens>".  It appears that this is the case here, so manually removing the " or ..." to give the OEM lens name seems to be what you need.

Guess I will stick to what works! Thanks! Incidentally I checked with Exiftool Gui and could not find any lens id field. However, PhotoME shows a pair of numbers 3 + 52  for the field lens id. Whatever that means.

Thanks for your tips. At least now I have a working method to add the lens info from the MakerNotes to lens info in EXIF.
