Hi guys and gals, I took my GW690 out of the camera bag after returning from a photo trip, and noticed that the lens didn't feel right. If I put my fingers on the shutter speed ring and rock it back and forth, it wobbles, so that the tiny space between the shutter speed ring and the aperture ring gets larger and smaller. I can still change the shutter speeds, and they still seem to be accurate. It's like the front of the lens has come slightly unglued, or unscrewed. It feels like a loose filter that wants to be tightened, but of course there's nothing to turn to tighten it. Anyone seen something like this with your GW or GWS?
