Hi, just picked up my first Leica. A V-lux1. The person I bought it from told me it was mint and in perfect working condition. I notice when outdoors in bright areas, when I press the shutter button half way to focus, I see a very fast flicker of white on the LCD or the Electronic viewfinder. Doesn't appear to happen indoors in normal room lighting. Is this a common problem? I hope I didn't buy a broken camera. Everything else works perfectly on the camera and it get very good sharp images....
