OKTO35 Mk3 3D-PRINTED ANALOG FILM MOVIE CAMERA

Building the preproduction OKTO35 Mk3 camera is in full swing. It will be better and a more refined version than Mk2 with many new features, parts/cost optimization, improved design, and a better overall user experience. After a successful build, it will be thoroughly tested and reevaluated. In the meantime, you can participate in a more in-depth project discussion in the comment section at the bottom of this page.

What is possibly to come from the OKTO35 Mk3 camera?

  • film scanning procedure using a smartphone via a wireless connection
  • crystal-sync true shooting FPS speed, enabling perfect sound recording synchronization
  • possible external film magazine add-on for longer shooting time
  • increased shooting FPS range from 1 to at least 24 frames per second
  • bigger C-mount lens support
  • variable film frame gate size
  • charging via USB-C connection
  • replaceable battery
  • reduced running noise due to a quieter stepper motor
  • reduction in film shake and better mid-exposure frame stabilization
  • simplified and more robust external and internal design
  • more defined film frame edges with reduced neighboring track bleed-in
  • and more …

Please note, that some progress updates may take longer to appear due to unpredictable project development problems or life events down the road. At the end of the day, I’m only human :/

Progress update #1 (Film advance drive)

Progress update #2 (PCB design/assembly/test)

Progress update #3 (New viewfinder)

Ideas, feedback, suggestions? Let me know.

  1. as color negative film has become expensive since corona, its time to use black and white stock and impregnate it with dyed potato starch grains for autochrome process, if scanned anyways the saturation can be fixed in post

  2. Hello,
    I admire the work you do and the OKTO35 camera you have made. I’ve thought before about taking on the venture of creating my own film camera in the future, and it’s very cool to see someone actually have done it. I like also the thoughts towards stop motion use, I think animation takes a more composed form on film than digital. Overall, I think what you are doing is a great thing, such for forwarding a small niche in the world.

    Hey this is amazing!

    You’re super clever. Keep me posted on the direction the project goes

    If it’s downloadable that be cool but it would be way more fun to either be for sale or a Kickstarter

    Also if you want I’d love to try one out, got a fridge full of film and access to a darkroom I might even be able to pay shipping if you’re willing.

  4. Any new updates on this? I’ve been waiting eagerly since the last YouTube video, very excited for this to come to market.

  5. I’m very excited for this! Brilliant idea and great follow through with the product creation. Whether it comes to market as files for 3D printing the components requiring complete assembly, or as a fully assembled product, or combination thereof, it’s going to be very successful! I hope I’ll be able to experience the Okto35 as soon as the product becomes available. Thank you Blaz!

  6. Hey! How goes the project?

    I was also (on a technical level) curious: have you ever explored rotary prism mechanisms or spinning mirror type designs? That’s how a lot of the old high speed film cameras were designed, maybe that could come in handy!

    1. My apologies for the late response. Yes, I was thinking of a spinning prism shutter as an alternative to the current solenoid shutter. But sadly the spinning prism kind requires a very precise and stable (constant) linear film advance, basically like a conveyor belt. The prism rotation must also be in perfect sync with the film advance (mechanically coupled). This would be too complicated to achieve with 3D-printed parts. A stepper acting like an intermittent advance mechanism with a simple shutter is a much better solution as both are already synched together via software control. Anyway, thanks for the idea proposal 🙂

    2. when you rotate a prism in front of a non moving black and white cmos camera sensor you get a multispectral image, from which you can derive some things…

  7. Hi,
    I‘m wondering, the OKTO35 MK2 is Open source?Could you send me the printing files,the hardware and the software?

    thanks,

  8. Hi,
    I am wondering, how could I buy one of the okto 35 mk 2’s? could you send me the printing files? or do I have to order it strait from you?

    thanks,
    Sam

    1. He is working on the next iteration first, so you can’t purchase the current mk2 version. It is made of many parts, so just the printer files won’t suffice.
