Please do tell me. Right now i just experimented putting a very small piece of rubber band under the spring inside the hotshoe.
The camera came with the zeiss ovf as well as sony's evf so it was the ovf that got dropped. I had two cameras in my Billingham small and it was tight with the ovf attached. When I took it out it must have been half lose. And it seems like if half lose it will just fall out. It hit my car's bumper and fell onto the street. Luckily it was only a small paint that came off at the corner. Is not that visible, but it gotta hurt.... few hrs of use only. I'm surprise the glass itself is still perfectly fine.
