Strange *ist ds behavior

I got an interesting story about my *ist ds. So yesterday, I had my Sigma 28mm on, and wanted to switch to my telephoto (Tamron adaptall-2 80-210mm). So I switched lenses, and then turned the camera back on, and the shutter wouldn't fire. The little green viewfinder displays wouldn't light up, but all the menus and stuff worked (also, the command dial wouldn't work). Also, whenever I pushed any buttons, the camera would make a faint click/shuddering sound.

I put the Sigma back on, and switched between auto and manual focus, and took the batteries out and everything, but alas, nothing happened.

I remembered reading somewhere about other people's cameras behaving similarly, and in general it involved low batteries. I charged up my batteries and put them in, and same problem.

Finally, I was ready to reflash the camera's firmware, but decided to just stick on my Pentax F 50mm. All of a sudden, the camera started working fine. I put the Sigma back on, and it was working fine.

I guess my *ist ds missed it's Pentax brethren.

Anyways, I just wanted to share my story and see if anyone else had similar issues.

Maybe you had a little dirt or something on the contacts and it just happened that putting the 50mm on cleared what ever was there? Other then that maybe camera gremlins
