I have 3 non-CPU lenses configured in my D600. Fairly often, I will forget to check and change the non-CPU lens selection. This doesn't seem to affect anything except the focal length and possibly aperture values recorded in the metadata. Not a big deal in the grand scheme of things, but it bugs me - I like my metadata to be correct.
Is there any software (preferably free) that allows me to change focal length and aperture in a NEF file? Lightroom allows some fields to be changed, but not those. Opanda only works with JPEG and TIFF.
EXIFTool does the job! But, it is a command line utility so not very user friendly. Extremely powerful and flexible, but one must be careful with it.
LensTagger does the job from within Lightroom! This is exactly what I was hoping for. It allows one to edit lens info in the metadata, including the lens name. It makes it possible to use Lightroom's library filters to work with non-CPU lenses - they don't all get grouped under "0.0mm f/0.0". There seems to be a way to save and recall lens presets, but I haven't got that working yet.
EXIFTool GUI works perfectly to display the metadata, far more than any other program I've tried. But, I was not able to make it update the metadata in a NEF file. I only spent a few minutes with it, I am probably missing a something. I will need to spend more time with it.
EXIFTool GUI will do what you want. Spend a little time with it and you will figure it out.
Another useful one is EXIFCopier available at http://exifcopier/.110mb.com IT also uses EXIFTool, but simplifies batch EXIF copying, backup, restoration and extraction of JPG's from NEF's, based on directories and file extensions. It's slick.
