Hasselblad Mirror lock up problem
So I just got my 500CM, I was trying the mirror lock up function on it but noticed that the primary shutter was opening as well when I hit the switch. It wasn't doing the selected shutter speed, it would just sort of half-open and then slowly close. After it was closed I could fire the primary shutter like normal. Is there anyway I could fix this? All the shutter speeds sound right when I fire the camera, and a polaroid I took came out alright. The lens is an 80mm CF.
