I have a number of vintage lenses and since I am mounting them on a digital camera the lens information isn't available.

Strangely, my photos have the information of the last digital lens that I used on my camera (a Canon 60D). This is kind of annoying as I sometimes browse my photos and it's giving me the wrong information, similarly when people look at those photos they get wrong info.

How do I set the lens info manually, either in camera or with an application? How do I remove the wrong lens info?

  • You haven't indicated what kind of lens, or adapter you use. In case it's an M42 adapter this question might be relevant or even a duplicate. Mar 25, 2020 at 10:49
  • @SaaruLindestøkke, it's actually fine whether or not the adapter/lens is M42. I've retitled the older question to genericize for any adapter with an EMF chip glued to it. :) Thanks for catching that.

  • @SaaruLindestøkke how can it be the same question as mine while it's talking about the differences between AF chips and I'm asking how to set/reset this info. The person who asked that, seems to know about this chip that I had no idea until now

  • It's not exactly the same question (and I haven't voted to close either), but your question seemed to be looking for a similar thing from a different angle. Mar 25, 2020 at 23:30
  • @xbmono, when we say something's a duplicate around here, we often mean that the question will have duplicate answers, even though the questions can be phrased very differently.

The easiest way to get some lens EXIF information, such as the focal length of the lens, is to find a chip for your adapter ring that fakes being a Canon EF lens chip. These can be programmed to push out EXIF information, as well as perform AF confirmation, and hold AF adjustment settings. I used to use the EMF chips back when I shot Canon with adapted lenses, because you could, iirc, also program it to include the actual aperture setting you were using at the time.

See: Will an adapter with an EMF AF Confirm chip work with my vintage lens?

But you can also add or edit the lens EXIF information after the fact using the command-line exiftool or its library, or any of the GUIs that use them. Because I'm a Lightroom user, the donationware LensTagger plugin is my tool of choice, because it can save off information for a specific lens (and film) combo and then reload it, so if you use a number of different adapted lenses, you aren't having to refill in all the fields over and over. But it's a bit of the PITA, as you have to also make sure to get Lightroom to update the database after you've written to the files' EXIF.

If you are willing to do it after the fact, any of the leading EXIF info editors are capable of doing this.

ExifTool is probably the most widely recognized and used application for editing pretty much any field in the EXIF info for an image file.
