If you are struggeling with corrcet focus on your Mamiya RB67, this is for you. You can get the adapter by contacting me via this marketplace post on Facebook / 4195572970476424
After investigating possible mechanical causes for out of focus photographs (keep in mind my viewfinder shows perfect focus), it occurred to me that I needed a way to see how sharp an image was when it landed on the film plane. From there I would know which way to adjust the focus screen (up or down) to correct the issue. The method would have to be precise and would require magnifying the image on the film plane. I considered coming up with a hack myself, but then I found David’s solution; a well crafted, extremely precise, 3D printed adapter. It is easy to set up, and was designed to be used in tandem with both the RB67’s existing focus screen as well as the hood/magnifier. David was quick to respond to my questions, and equally fast in producing and shipping my adapter. I highly recommend his design and was thankful for his attention to detail regarding manufacture. His is a very clever solution, and now my focusing issues are solved.
Brilliant idea. Im curious of a link & price . However, can i just use a modified Graflok film back with 2x3 ground glass in place of film? Do i need to compensate doe film thickness ?
Not related to the back which I have and is great btw but which model grip is that? I’ve been holding out for the multi angle grip but that one looks good and I’ve been waiting a while now for a multi angle to come up.
That is a grip i have 3D printed. I cannot take credit for it, but you can find it and print it from Thingiverse - search for RZ67 and it will show up :-)

Thank you for your kind review :-)
Great video demonstration! Thanks for making it and for making parts and helping us with out RB's.
Love it! Do you still produce the focus checking adapter!?

There are focusing screens for the Mamiya Universal system
You can use them with a P adapter on your RB
Do you know where I can get the tool used to adjust the screws for the ground glass?

@@davidb4010 Wow. I don’t have a 3D printer but it’s great seeing what’s possible with them. 👍🏻
How can we buy this adaptor? :) Thanks
Looking to buy one
