Am new to medium format, i borrowed a Mamiya AF 45mm F 2.8 lens and whenever i try to click any photo the mirror goes up and remains there until i switch of body and back...
The Mamiya AF 45mm focuses ok but am not able to click any photo and whenever i connect the lens and start body and back there is some sound coming from either body or lens
while the body and back works perfectly with my schneider kreuznach 80 mm lens.. am i missing something ?
