Our focus gear module on our JVC KY-19 3ccd was pulled out off the servo ring just the other day, and we were able to get by with a bolt just a bit larger to take the threads and hold it on. Now, somehow the zoom ring has locked itself and will not allow for either servo or manual adjustment. I'm on the hunt for a new lens to replace it. Does anyone know of any lenses out there that could replace this now damaged one. I've been on ebay and have seen a fair amount of used lenses for sale. I'm curious how to determine if any of these lenses out there would work with our older JVC KY-19.
