Hey Andy,
..So that's what that slot is!!! Was wondering when I bought it what it was used for!! Was also wondering about the piece that I found at the bottom of the box. It looks a bit like a pull tab from a soda can and fits into the before mentioned slot and has a lightbulb marking on it. I guess that's the key to switch off the internal 85 filter. As for the lens, it's a Vario-Sonnar 9-36mm, very nice still, no scratches at all. I had thought it needed adaptor rings because it has flanges on it but i guess that's for the lense hood(?). Gettting even more psyched about this camera!! Thanks a lot for the info again Andy. Just another question..there's a screw in the front of the camera, just above the lens. Any idea as to what it's used for ?..
