    This is the only other one I know of and it's the same price as the speedbooster and isn't powered by the camera (and obviously isn't making your lenses wider and faster).

    There are a few decent aperture controlled adapters for EF, but the good ones are similarly priced. If you are talking about focal reducers, there are none worth buying other than the speedbooster, without seriously compromising IQ.

    That's the one I linked to above. It's the same price as the active mft speed booster and $50 cheaper than the bmpcc specific speed booster.

    There are plenty of knock off speedboosters, although if you listen to people round here you would believe they are unusable (strangely enough, lots of people are using them daily, for great results)

    Rj camera
    Roxsen
    Camidiox
    Zyhonghi (spelling ?)

    Most people are recommending the RJ right now (if the Metabones is a bit pricey)

    Redrock Micro Live Lens (mentioned above):
    http://store.redrockmicro.com/livelensmft.html

    MTF Services EFFECT:
    https://www.lensadaptor.com/mtf-effe...micro-43-mount
    plus the control box:
    https://www.lensadaptor.com/mtf-effect-control-unit-2

    Neither include any focal reduction tho but both will work on the passive mount of the BMCC.


    Pretty much every other focal reducer I've seen are really not up to the task.
