I had quite an experience the other day, and was wondering if anyone might have a possible explanation.
I picked up another 800E, and after charging the battery, etc. I put on a lens (Zeiss 35mm), pointed the camera at our woodstove, focused carefully, and released the shutter. The camera made a terrible, screeching sound and "Err" began flashing on the top LCD screen.
Thinking quickly, I banged the camera on the table a few times, turned it off then back on, removed the lens and fired the camera again. This time everything seemed normal. I replaced the lens, and haven't had any problems since.
Any ideas about what could have caused something like that? Yes, the camera was set for manual focus, and the lens was installed correctly-- the picture of the woodstove was fine.
It's obviously not a big deal since everything's working now, but I was just curious if anyone else has had anything similar happen to them.
By the way, I was just kidding about banging the camera on the table-- I'm not as dumb as my mom said. :~)
