Bringing the OKTO35 Mk3 camera to life is in full swing. This will be a new and improved version with parts/cost optimization and ready for the first beta testers.

What is there to expect from the new OKTO35 Mk3 camera?
In addition to OKTO35 Mk2’s specs, there should also be:

  • optical TTL viewfinder with ground glass for focus and framing check
  • side optical viewfinder with OLED framing and information-assisted overlay
  • enlarged dual gate exposure size in 4:3 (6.3×4.7 mm) and 16:9 (8.4×4.7 mm)
  • crystal-sync speed framerate 1 – 25 FPS
  • electronically variable shutter angle 90 – 180°
  • possibility of an external film magazine for increased shooting time
  • frame-by-frame sync scanning via DSLR/Mirrorless and smartphone camera
  • larger C-mount lens support
  • new and more precise frame advance system for reduced gate weave effect
  • reduction in film track in-between bleed-out effect
  • reduction in camera’s running noise
  • battery charging and firmware update via USB-C connector
  • user replaceable internal 18650 rechargeable battery

Please be aware that some progress updates can take longer to appear due to project development challenges and life unpredictability. At the end of the day, I’m only a human.

    This looks absolutely amazing! Could you please share the latest progress update? When is the estimated release date, or will beta units be available for purchase soon?

      Thanks for the kind words!

      My next update video will contain new Okto35 Mk3 camera presentation + demo. Had some setbacks lately, but shouldn’t be too long.
      You can DM me via email if you’re interested in beta testing.

    This is pretty awesome. Have you considered a version where you replace like 90-100% of the electronics with a crank (and I guess manual track shift), a la lomokino but way better?

      Thanks for the kind words!

      Having it without the electronics and motors with a direct crank linkage would be a whole different beast to conquer.
      However, for the upcoming Mk3, there is a non-zero chance of having a hand crank function. Similar to a Lomokino, but way better.

    Heyyyyy

    Amazing project… If there’s a possibility I would love to beta test it.

    Thanks,

    Amazing idea, looking forword to the final version. I am wondering when will be the purchasable version avaliable?

      Thanks for the interest!
      After the Mk3 version is finished and beta-tested, you could expect the first camera batch for sale.

    This project is simply the amazing, and I was wondering if you could share a list of materials alomg with the 3D files, because even though it does look like a deeply complicated project, I would like to do this for my science fair this year, of course crediting you for the idea.

      Thanks for the kind words!
      The project is currently closed sourced type. But there is a chance of releasing some DIY files in the future.
      The camera is/will be a very complex design with high-density electronics, sensors, and motors, with tight tolerances 3D design that is needed for overall good image quality.

    Hi Blaz,

    A couple of questions…
    What is the total run time of the 35mm roll?
    Will you be doing a Kickstarter campaign?
    Will you be selling a complete and fully built camera?
    You mention crystal sync, does that mean users will be able to shoot synchronized sound with the right equipment?

    1. Blaž Semprimožnik Avatar

      The total runtime is 1min and 7sec @18fps on one 36-exposure 35mm roll.
      There is a big possibility on a such campaign in a form of fully built camera.
      Yes, the Mk3 version will have crystal sync capability on all FPS range. Sync sound recording should be possible.

        Is there seamless transition between the 4 different “lanes” of exposure, or should you time your shots to more close to 4 times 15-16 seconds?

        1. Blaž Semprimožnik Avatar

          There is and will be a transition period between 4 different tracks, sadly it can’t be avoided.
          But I’m aiming for the shortest period possible, somewhere around 1-2 seconds.
          In a sense, almost a seamless transition.

    Brilliant! I was playing around with a crude version of this concept in the late 1980s. It was a failure, but at least I tried…

    I would love to beta test this!

      Great to hear that!

    My man I NEED to shoot with this. I don’t care how prototype-y its state is, i just need it in my life. Any chance I could get my hands on an earlier build? I’d be happy to print it out myself if you can send the necessary bespoke electronics.

    1. Blaž Semprimožnik Avatar

      Completely understand you.
      I’ll need some beta testers once the Mk3 is finished. DM me via contact email for more info.

    This whole thing is blowing my mind, I can’t believe the lengths you’re going to here and I can’t wait to see more as time goes on!

    I am a big fan of your project! I am interested in beta testing your camera. I also have a 3d printer if you plan on sharing source files in the future. Looking forward to hearing from you. Cheers

      Glad to hear that!
      Hold on to your 3D printer, there may be a chance of a DIY version in the future.
