Thanks all for the advice/support. issue seems to be still present. im going to leave it to a repair shop to figure out. thanks again.

So the ground glass is the glass around the split/circle? sorry.

Im using split image focusing aid by looking at the ground glass through an eye loupe. 55mm split is lined up perfectly (that's the lens i calibrated with) .. 80mm is off quite noticeably and i have a 150mm that's also off but hardly noticeable.

ok i seem to have fixed the issue. The glass that sits above the focusing screen has what looks like a thin removable plastic frame. This was actually installed below the clear glass and not above it. Swapping this round seems to have fixed the problem. I can now reach and pass infinity using...

Mirror stop is removed. While lowering the mirror from top to very bottom, it never reaches infinity. That's exactly my issue! Its super strange.

As far as i can see, there is only one place for the focusing screen. Ive inserted it a few times to make sure and it seems correct.

Sure, but wouldn't is see infinity be passed before i reached the bottom of the mirror box?.. what's happening is, if the mirror could go a couple of mm past the bottom of the mirror box infinity would finally be reached, but obviously that cannot be done. I would have expected infinity to be...

sure.. but that's not what my problem is.

Probably best to start your own thread regarding this question.. just so mine does not get hijacked! :wink:

That's all good advice thank you. But what i can't understand is, even when the mirror stop is completely removed the focus still does not quite reach infinity? you would expect it to pass infinity with the mirror stop removed right? Thank you.

Never mind i think im now where i need to be. But thank you for your help.

Yes, this is exactly where I am at. I have done what you have suggested and still infinity focus is not possible, I just wanted to confirm thats all i can really do without sending in for a check up/repair. Thank you for being on the same page.

So you're saying a faulty mirror stop does not effect focusing issues? Ive never heard that before.

Thanks, the screw is not tight.. also even with the mirror stop removed and the mirror seated at its lowest position, it still can't reach infinity. So that goes against what you say about the mirror seated too low. For me the mirror is not low enough? even with the mirror stop removed!

Hello all, Ive joined the forum in the hope someone can help me with a focusing issue. I have the mamiya 645 super. I bought it second hand. I have shot 3 rolls of film using 80mm and 55mm lenses. All the photos i received back are clearly out of focus. It appears the camera is focusing behind...
