Mamiya RB67 mirror is stucked

[Patrick G]

I just got my mamiya RB67 Pro S and seems like the mirror got stuck out of nowhere. I’ve tried many possible solutions externally but couldn’t seem to figure it out. I basically got this 1 day ago and I already broke it. Please help.

Hi Patrick,
open left side and get it free. Not a big deal.
There are lots of tutorials in the web.
Good luck!

Does the shutter cock?
Can you remove the lens?
Can you remove the film holder and rotating adapter?

What do you mean by open left side?

I'm thinking that you simply attached the lens with the mirror up which will lock up everything, as the lens should only be removable with the mirror down and shutter cocked. If one is not right it will lock everything up.

If you remove the lens can you then move the cocking lever on the body that lowers the mirror? If that works now look at the lens, can you see through it? If so that's good that means the shutter is cocked and you should be able to reattach the lens and be good to go. If you can't see through the lens you need to cock the shutter by rotating the two pins on the rear of the lens counterclockwise until they line up with the green dots, the shutter is now cocked. With the shutter and body both cocked you should be able to reattach the lens and be good to go. Note: If you want to fire the body with an empty film back attached you will need to have the dark slide out and the the multi exposure switch set to multiple, with the back removed nothing special is required just wind and fire.

The most mechanical part is under the hood on the left side, specially the mechanic for the mirror. There are tons of tutorials in the web how to get the stuck mirror loosened and repaired.
The RB needs a little bit of CLA in the mechanics.

The Left Side should refer to the side that is on your left when you hold the camera in normal shooting position ie you are going to take a picture.

Sorry, yes, thought this would be normal and well known.

It is normal and common read my above post before removing the side of the body.
