    That's very clever. Albeit a bit limited to wide angle lenses due to the focus throw. 50mm lens needs about 1/2" throw to get half decent close focus. I don't think this adapter can do that...

That adapter allows for continuous autofocus as well! https://techartpro.com/product/techa...focus-adapter/
    Now that is VERY interesting. I'd like to use autofocus on a C200, which is the first AF I've trusted enough to use for professional jobs, but that doesn't look like it's possible with this adapter. It's still a great find. I'd never heard of it before and hope they keep working on this tech.

    I hope one of the lens manufacturers sees this and tries the market with something like a rehoused Helios or maybe a Canon FD with AF and IS. I don't know if this is just science fiction, but the idea of one in a CP.2 style cine lens housing would be even better (but maybe prohibitively expensive).

    Yeah, the flange distance wouldn't allow for this to work on an EF or PL mount camera.

    This video actually explains really well how you can obtain an even shorter minimum focus distance with certain lenses and the adapter:

    That's true that will work as long as you preset the lens for the range desired. That should not be too hard to do even on the set/location.

    Having used the techart I would not really suggest it as a solution for cinema use. Motors are fairly slow and steppy. This is not intended as a slight against the company, I think the product is very interesting engineering but personally I'm hesitant to use it for still photography autofocus much less anything motion picture related. Maybe some next gen version of the technology?
