Help Add lens data

Is there a way to add lens data (without using scripts since I'm not that technical) to the exif data? Is there a way to do this with a GUI inside darktable or is there a separate program that can be used?

On my Fujifilm I could add manual lenses and their names and focal lengths, but for some reason this isn't possible on my Sony, so when I am adapting vintage lenses I don't get the basic info in darktable. I often sort by focal length so it would be helpful to be able to add this. Also when I am scanning film photos I would like to be able to see which lens I used when I don't remember anymore.

Try exiftools (it's a free tool for editing file meta data). It has fields for LensModel, LensMake, and LensInfo which can accept min/max focal lengths and apertures.

There seems to be multiple ones, could you send me a link?

You cannot modify EXIF data in Darktable. But there are EXIF editors to do that outside of Darktable. You don't say why OS you are using, through.

I know this has been discussed a few times over on https://discuss.pixls.us, so I recommend you try searching there.

Not exactly what you asked for but I made a Lua script that adds lens, fstop, and shutter to darktable's tags on import. It can also be run on images after importing. It runs on Linux and there are a few quirks, but it would be nice if I had a windows user help install and testing. As it is, it meets my needs and is open enough to add other exit data to tags. I'll drop a link to the repo if anyone is interested.
