speed booster for the chronos to reduce crop on full frame lenses

(1/4) > >>

patrickrebstock:
i was dreaming about taking a bmpcc speed booster and taking off the Micro 4/3 mount and having a csmount machined , but alas the glass of the speed booster sticks out too far
anybody else have any crazy ideas with more luck to decrease fov?

tesla500:
We actually just prototyped this, not with a BMPCC speed booster however, just a low cost Chinese one, but it works very well. Speed boosters that have an MFT mount seem to be the most common, but it's not possible to convert MFT to C mount. MFT to CS mount is just possible, but no one makes that adapter. We're going to custom make our own once we have some time to design it.

John DeLonghi:
Nathan at Aimed Research has made a few adapters to achieve this and he very kindly supplied me with one a couple of months ago. I can confirm it works very well with a Metabones Speedbooster and I'm shooting everything through it from now on.

In a few days I should have some nice test footage done using a Metabones XL and Nikon lenses and i'll post some of it in the footage thread so you can see how it looks.

great to see others were thinking the same thing! keep me up to date on the progress, or if you need help i do mechanical engineering work mainly solidworks
