  • Time of Flight Autofocus is here!

    Introducing ToF Continuous Autofocus using Tilta Nucleus System!

    https://vimeo.com/358522342


    This demonstration shows ToF ( time of flight ) autofocus on:
    -BMPCC4K
    -Sigma 20mm 1.8 Lens
    -Nucleus-Nano

    The way the system works is a time of flight sensor is attached to the top of the camera, measuring a point of distance centered in the frame. With the distance measurement the lens’s focus is set precisely to that distance in realtime.

    The prototype has promising applications, mainly in that it is completely camera/platform independent. Will work on any camera system, because it doesn’t need to interface with any camera control protocols to focus the lens. Instead using physical motor control with the Nucleus-Nano ( or Nucleus-M )

    Also means, you can autofocus manual/cine lenses!

    Lens’s will need to be calibrated on this system, meaning you will have to manually map the distance marks of your lens into the system. This can vary from lens to lens and based on your motor’s calibration on that lens. Lens profiles can be implemented to make this process less tedious.

    Some other quirks and drawbacks:
    -ToF can have trouble measuring distance on some surfaces
    -Single point of measure in the frame, and rather narrow angle of view for the measurement.

    Please leave your feedback in this strawpoll: https://www.strawpoll.me/18606536
    This will help me gauge demand and influence production of these units.

    Still early stages, still need to design physical hardware and improve the software so further optimizations and improvements are to be made. So stay tuned!

    Very interesting concept! How will it work with Manual focusing wheel? Is it possible some seamless usage of manual control during autofocusing? Or is it will work only as hard switch? only manual/only autofocus

      I end up at "Love Bite: Laurie Lipton and Her Disturbing Black & White Drawings” with that link.
