zinstax for RZ67

shoot instax with your RZ and blow people away


Available on backorder


Hello! Thanks for considering purchasing a zinstax for your RZ67.

If you’re here, chances are that you’re already pretty familiar with the zinstax. It’s a custom film back that is 100% hand made which enables you to shoot instax square films with your beloved RZ67.


  • No spreading issues: it’s based on Fuji’s SQ1 camera
  • Made to match RZ’s flange focal distance: perfect focus (see 9th image for a focus test from a customer. And here’s Jihoon’s reaction)
  • Working film counter
  • Activates both horizontal and vertical viewfinder masks: what you see in the viewfinder is (approx.) what you’ll get. More on that below
  • You can shoot in horizontal or vertical position
  • Fully mechanical, will probably outlast your RZ if used with care
  • Comes with a stainless steel dark slide and built-in metal light seal that’ll never wear out
  • Dark slide holder on the film door which also prevents the film latch from opening by accident
  • No “hand crafted in Germany” engraving or serialized gold embossed certificate with a fancy signature
  • Wouldn’t recommend using zinstax with a prism finder but you do you
  • Balenciaga’s latest campaign is shot with zinstax: Fall 22 Campaign


Longer version:

It’s fully mechanical, so no batteries are needed. I’ve had an electric Polaroid back for my RZ and once I took it out for a spin only to find out the battery was dead. I ended up carrying my RZ with a useless back around for half a day in the city. The experience wasn’t great to say at least. And anything electric will die, eventually. The electrolyte in the capacitors will dry out until it can’t hold a charge, the lithium ion battery will continuously degrade to such an extent that it can’t even make it to eject a single film. Oh you mean RZ is electric too? (Surprised pikachu)

I digress. I just wanted to say that you don’t need to keep in mind to charge it, and you don’t need to bring a charger or spare batteries when you go on a long trip with it. And it works even when it’s extremely cold outside, because, well, it doesn’t rely on batteries. Also, being fully mechanical means you probably don’t need an oscilloscope or a soldering iron to repair it, if it ever breaks, that is.

I’m also extremely proud of the light seal design. It’s basically a piece of springy metal which automatically blocks the dark slide slot when the dark slide is being pulled out. It’s so simple, robust and effective, and will probably never wear out.

I’ve build a dark slide holder onto the film door. You can place the dark slide into it when you’re shooting, it also adds the extra functionality of blocking the film door latch so you won’t open it by accident and potentially ruin your film.

I’ve tweaked the face of zinstax so that it activates both horizontal and vertical viewfinder masks in the RZ67 when it’s in the right position. The reason behind this is that the rear opening of the RZ67 is roughly 70mm x 70mm and it extends either the horizontal or the vertical masks to make the viewfinder 7×6 or 6×7, respectively. By activating both masks, you get a 6×6 viewfinder, which is about the same size as the image area of an instax square film (62mm x 62mm). Illuminati confirmed? No, seriously, that coincidence is awesome: what you see in the viewfinder is approximately what you will get. It’s worth noting that zinstax doesn’t do it any differently than other 120 or 220 backs, which means there’s no harm to your RZ.

I have to sleep now i’ve been staying up late a whole week straight i need to see a doctor bye
