Go to the Lens Info setting in the camera menu, you can add the name, focal length and max aperture. Then when you use the lens, just go in and select it and it will automatically adjust the IBIS for the focal length and will right the name of the lens to the EXIF data. I am assuming this is your only lens without electric contacts so when you mount this lens after using a lens that does have contacts, it will sense a manual lens and use the last used info setting.My first TT Artisan lens. I must say, this thing is one solid hunk of glass and metal. It's fully manual too, as the camera doesn't even pick up anything in the EXIF. I'll have to remember to do the manual lens setting or add it in post. Aperture will always be a guess though.
