Simple question re MakerNotes tag writing

[Archive]

[Originally posted by dcnicholls on 2007-10-27 07:01:17-07]

I'm trying to get ExifTool (the Windows executable exiftool.exe) to write a Minolta tag, LensID, to an image.

My current sub-string in the command line is (for example): -LensID="Minolta AF 100-300mm F4.5-5.6 APO [New]"  This doesn't give an error but the LensID isn't written to the file.

If I use  the number equivalent ...=7 or other number I get a Cannot convert message - either "matches more than one PrintConv" or (as I'd expected) "not in PrintConv"

To get exiftool.exe to write the LendID tag, do I need additional library files or to add something to the config file .ExifTool_config (which I'm already using for a custom tag)?

TIA

What type of camera is this?  You can't add makernote tags that don't
exist in the original image.  Also, you need to use the -n
option when setting LensID to the numerical value. (Faq #6)

If the lensID tag doesn't exist, I suggest using the XMP:Lens tag
instead if you want to add this information.

Thanks.  I didn't appreciate you can't introduce makernotes tags. I'm trying to add exif data to scans from negatives.  I have already discovered the use of the XMP:Lens tag and have used it.  It's a fully satisfactory solution.
