Shimming DZOFilm 20-55mm With BPMCC6k

I just picked up a DZOFilm Pictor 20-55mm zoom that will be going on my BMPCC6K and I need to change the mount over from PL to EF. Does anyone know the proper procedure to dialing this in with the shims?

There doesn't seem to be any documentation from DZOFilm available and I want to be sure I'm doing it right.

Thanks!

Of course, one I post this I think I figured it out. Their website wasn't loading for me for the past couple days so I cant really say if this is hidden on there somewhere but I did stumble upon this YouTube video!

Hopefully this helps someone else.

That’s the guess and check method, it doesn’t require a Siemen’s star. Zoom in focus, zoom out, if focus moves toward you then add shims, away, then remove them. If the difference between S1 and S2 isn’t correlated to shim thickness it’s going to take a few tries. Zeiss has a system where the focus offset corresponds to the correct color/depth shim making it a one and done process.

Good Luck

Edit: This is similar to the Zeiss, chart is on p6, one and done.

That video is nice. The manual is on the DZOFilm website, and it details the methods shown in the video above.

For my 20-55 it has a base Shim of 0.5mm for the PL and I add 0.17mm on top for the EF Mount. From what others have said on Facebook Groups it varies lens to lens. That's fine. But once you determine the right shim amount I would save a note with the base PL value and then the EF value for future reference when switching the mounts.

I really love the lenses. Lens comparison video is releasing soon. I think they were putting finishing touches on it today for release tomorrow.

Video is finally out:
