New Canon EF Lens to MFT Speed Booster (CEFMFT) works on BMPCC? I have the Canon EF Lens to BMPCC Speed Booster (CEFBMPCC), but if CEFMFT works on both systems, then it is a more flexible adapter, in which case I'd return the CEFBMPCC...or am I'm out of my marbles?

The chart on the Metabones web site would seem to say that theEF - BMPCC as not the same as the M43 version.

Jim, I think you are right, I must have misread it somewhere or wished it to be true, regardless, testing the BMPCC Speed Booster has pleased me, so far anyway

Glad to hear it's working well for you. I have two on order right now so nice to know I didn't order something that won't work/

The Canon EF Lens to MFT Speed Booster does work with the pocket camera.
It doesn't produce an as wide or as bright picture as the unit designed for the BMPCC.

Well thinking about it some more I remembered that the sensor sizes are a lot different, so that would affect the result of using the MFT speedbooster on a BMPCC

The diagonal of the MFT sensor is 22.5mm and the BMPCC is14.3mm. So optical performance would be different even though the mount is the same.

Also not 100% sure if the interface to the cameras is the same. I seem to recall some things that the BMPCC version supports but not the MFT version.

But as usual I could be wrong about anything and everything:<)

the Pocket is a 16mm size chip, so you will not get the added re-gain of as much of the wide angle from the camera as the metabones unit made just for the Pocket. Also never mount the M4/3rd unit for the Pocket onto any other M4/3rd camera. It will probably cause damage due to the deeper setback from the flange.

from the Metabones site:

EOS to BMPCC
▪ Increase maximum aperture by*1*2/3stop. (with a maximum output aperture of f/0.74)
▪ Increase MTF.
▪ Makes lens 0.58x wider.
▪ Optics with 6 elements in 4 groups,

EOS to MFT
▪ Increase maximum aperture by*1*stop.*
▪ Increase MTF.
▪ Makes lens 0.71x wider.

The mft versions are designed for a sensor with a different filter stack thickness than the bmpcc version. They will both work but the bmpcc version will yield better results with that camera.
