Hi,
I just got a Hasselblad 500 El. Before I had a battery or lens I was trying to see if it would do anything when pressing the shutter release button, and when I set the selectot to SR. When I hit the shutter release, the mirror went up and the rear curtain went up. They are still up, and I have gotten a 9v adapter battery kit and installed. I set the selector to O and the camera just clicks and the mirror is still up and curtain also. I still dont have a lens yet. Do I need a lens for the mirror and curtain to come down? I got the camera on Ebay and just want to know if im missing something, or is something wrong.

Thanks for any advice

David
