Thanks, Steve. That fact that it works with exiftools and enables the work to 
be done from within LR is appealing. Thanks again for bringing it to my 
attention. It did not come up in any of my searches.

Thanks, Steve. I’m wondering what advantage, if any, there is of a plugin

you asked for a way to do it within Lightroom, so i assumed that would be an 
advantage for you; *if* the plug-in works well, i would think that would be

I understand that exiftool is the state of the art exif/metadata editor, that 
there is a gui for windows but not os x. 

Googling, I came across this mac-specific editor: . 
Are you familiar with it? If not, any opinions based on the information 
provided on the website.

Also, do you know anything about LensTagger, the LR plugin Steve suggested that 
relies on exiftool? I wonder if it could be considered a gui for mac for 
exiftools.

Thanks, Steve. I’m wondering what advantage, if any, there is of a plugin

Thanks, Igor. It seems so.

I do it using EXIFtool. There are a few steps to follow to do it right, but 
it's not difficult. 
I'll write up a procedure and post it later.

exiftool can do it; if you must do it within Lightroom, you could try this 
plug-in, which relies on exiftool:

Eric,

I am afraid the answer is no, not from LR.

In principle, there is software that that allows writing (editing) various 
information into EXIF (the portion of the image file where all the 
so-called "meta-data" is saved, including the focal length).


I haven't worked with ver. 5, but from what I know about both 3.x and
4.x, I assume Adobe have not added that capability to ver.5.x.

Best,

Igor
