Something to watch for with these cameras. I was checking the focus of my 50 f1.4ASPH, and had the camera tilted forward and it suddenly came off the tripod. I thought I had forgotten to close the clamp on the tripod head, but when I looked at the camera I could see what happened. I don’t know if this was just metal fatigue with my particular camera (which has never been dropped or abused), or an inherent design weakness.
