No, there is no Panasonic version of the Leica Q coming yet.

As you well know Leicas fixed lens cameras have been mostly “copies” of current Panasonic fixed lens cameras. Yet on June 11 Leica will announce a new Leica Q Full Frame fixed lens camera with 28mm f/1.7 lens. A few 43rumors readers asked me if the camera is made in collaboration with Panasonic and if there is a Panasonic version coming. Well, I have not heard a word about that. I have been told the next camera to be announced should be the FZ300 and after that the G8.
