I was on a trip in the Grand Canyon last week with my GM1 and kit lens. Two days into the trip, in the bottom of the canyon, the ring that you twist to zoom the lens just came off. Fortunately, I could still use the lens somewhat without the ring although it has since become very difficult to zoom at all. Unfortunately, I think it's out of warranty by a few weeks. Has anyone else had this happen? Any experiences with Panasonic (Canada) warranties? Any ideas how expensive or difficult a repair might be? I'm not sure if I should take it to a local repair place or send it off to Panasonic.
