    Depending on the coverage of the EF lens (needs to be slightly larger than 35mm Full Frame), it could work with some but not most lenses.

    I have contacted Metabones and their statement was roughly that a cine version of the RF -> EF 0,71 Speed Booster is currently not a priority for them.

    I read somewhere that Canon might be working on more RF mounts, and think I read they were doing an RF - RF with ND's in the middle. Would this be physically possible? Seems like it probably would not be, but perhaps that some sort of benefit of the RF lenses, that can be slightly different distances from the sensor?

    If that was the case it would be amazing to have an RF to RF KipperTie.

    For sure a RF to EF kippertie would be useful as well!

    Still one of the best upgrades I have made in the past few years is getting Kippertie mounts for my DSMC2 cameras. Thank you for creating them!

If anyone has this adapter and could take a full frame photo with it on to show exactly where it vignettes, it would be most helpful.

    While the new Canon RF glass looks fantastic, I also really love the idea of using EF glass and having that extra functionality the adapter provides. Being able to throw in an ND behind any lens, or add a speedbooster to gain a stop when the light is low is really appealing.
    Metabones says their speedbooster has an image circle of 28.2mm. Komodo is 30.56mm in FF so may vignette slightly. Similarly in HD (29.07mm), WS (29.34mm), and 2:1 (30.22mm). In 5.5K you should be safe (27.97mm).

    Cool! Wish it was the Cine version though.

    You are correct Robert.

    The addition of the control ring is a nice extra!
    But here's the question Jarred; will gimmicks like the control ring work with the Komodo?

    This might be off-topic but could you please make one for the L-Mount ?
    Thanks

    You mean a PL Revolva with swappable L / RF-mount since both systems have the same FFD of 20mm.
