Yes 

hello FD-M4/3 suitable Canon FD Lens and Micro 4/3 M4/3 Mount Camera .we have confirm your panasonic lumix gx85 is M4/3 mount,so the adapter ring can work with your camera 

If you are referring to the Panasonic DMC-G7, then yes, it will adapt any Canon FD mount lens to any micro 4/3 mount camera. Including yours. 

An adapter does NOT change the focal length regardless of what is mentioned in the 1st answer. The adapter *can* be used on a camera with a smaller sensor which would change the filed of view of a particular focal length.
