So I was just trying to get through the last shot to put some colour film in.
I depressed the mirror return while the shutter was still open as it was on 1/4th of a second shutter speed
The lever is stuck half way as is the mirror (though it can go up)
What do I need to do to reset this? I havent forced anything.
The lens unlocking ring will only turn half way, so I cant get the lens off.
