do you know whether it's possible to use an instax mini 7s? I think all of the wiring is the same, but the battery compartment is different.

Do for bronicaaaaaaa : ) pleaseeeeee

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 ?

really great video, works for rz67?

Love it! Do you still produce the focus checking adapter!?

Do you know where I can get the tool used to adjust the screws for the ground glass?

i would love to buy a ready to use one do you offer that ?

Hey David - I've owned an rb67 ProS body since early 2020 and have been weighing options for an instant solution. Glad to say I've landed on yours. Where can I go about placing an order for the most recent version of the Frankinstax? Thank you.

Hello David, I am very interested in printing this mod for my Mamiya, would you sell me the stl? for personal use I am from Chile and I cannot buy you in the facebook market

Looking to buy one

Is there anyway we could purchase the files to download? Amazing build 👏👏👏

are you still making these kits?? I would love to get one

hello..This article is no longer available?

So nice ! I have a SQ1, I would love a version to mount on my Hasselblad ! :)

Would love to see how good the images are. Actually seeing fantastic glass paired with the film and the results. What the film can do.

Hey David. Question: With the electronics rewiring you did, is it a single press for the film eject? I'm building a back with a mounting plate/dark slide assembly from an old Polaroid (pack film) back that I got for 8 dollars.

Expensive! oh my

Amazing, any chance of putting out a tutorial ?

How can I get the Polaroid back?

I need one for my RB67. Anyone have one for sale?

Could you create one for my RZ?

Make one for my Bronica SQ-A, insanely cool engineering!

This one is for a hassy?

Amazing !

wow, that disapointing end... please show the Pictures :D

Is there ever a chance for a hasselblad version?

need one for bronica etr

I need one like this one for my RB. David what’s your email address or Facebook?

Very impressive! But why? Could you do the same with a 6x7 digital sensor?

I love to have something like this for my Kiev 88 so I could shot some 6x6 on Instax Square. Maybe someday though.

You could put a 1k ohm resistor across those capacitor leads to drain it so it won't shock you.

Do you have anymore sample shots to view?

Hey man just curious if you would ever consider releasing the 3D print files?

Saving to buy one! Super impressive stuff. Keep doing your thing mate!

Quality!!!

How can we buy this adaptor? :) Thanks

Nice work! Planning on doing the same with a Kiev 88. Did you strip the paint off the sq1 or paint over it? Any gotchas I should be thinking about?

Do you have a RZ version?

There are focusing screens for the Mamiya Universal system You can use them with a P adapter on your RB

@david i cant seem to msg you on facebook, is there another way to contact you to get the adapter?

How did you manage to get the button to eject it just for one pic without having to hold it? You kept the original pcb or what? Thanks in advance

Hi David! Love your work on this. It might be the cleanest back out there. I was wondering if you’d be willing to create an SQ1 frankenstax back, with an offset mounting plate. My goal would be to shoot instax mini, where the center of the film aligns with the center of the lens.

Looks sharp/great! Will you be posting a clip showing the new one in action?

I can’t believe how few views this video has, it’s such an amazing and detailed guide! I regret that I have but 1 like to give…

Just wondering if you are going to upload a video with the making of the square mk2 , I am in the middle of trying to make a Bronica hackback and I am stuck with the wiring Some guidance would be much appreciated

I want to try making this for my Bronica sq-a with Instax sq6 back and I was wondering if the process is more or less the same Thanks

I’m gonna need one of these for a 2x3 Century Graflex with Graflok…wonder how I’m gonna manage that.

Cool camera, cool back, nice video…. no image result!? 🤔

Hi David , as I don't have a Facebook account (never will) I have to use TH-cam to contact you , I am asking you again is there any way you can make this for Bronica SQ ? It is definitely cool and exciting , I can send you my Bronica SQ-A Polaroid back you would probably need as its different from the Mamiya . You can cut it or whatever you need , I don't use it anyway Thank you V

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.
