Chronos User Discussion / Re: MetaBones Speed Booster EF-MFT XL 0.64X doesn't fit new M4/3 mount

« on: July 20, 2023, 06:59:42 PM »

Just for context, I'm very technically experienced with everything from PL mounts, E mounts, EF mount, Bayonet mounts, etc. and camera systems from Arri, RED, Sony, Canon, etc. (again, don't want to sound like a douche, but purely for context so anyone that replies can rule out inexperience)

I disassembled the mount, tried mounting the Speed Booster with just the mount detached from the camera body, etc, and it does seem this mount is machined improperly for some reason. Maybe a QC issue. Have you had any experiences with Chronos's customer service? I'm likely going to return for a new one at this point. I have a shoot coming up that needs ultra high speed and can't fit a Phantom into the current budget. 

Thanks again for replying -

 The Speed Booster simply will not turn more than about 10 degrees. Regular M4/3 lenses will indeed turn and lock on this mount though. And both the speedbooster and the lenses will attached to a GH6 and Black magic pocket 4k.

Hey All -

As the title says, the Speed Booster EF-MFT XL 0.64x doesn't screw into the Chronos M4/3 adapter for some reason. It's not a depth issue, it just literally will not turn past about 5mm. The Speed booster works very well on a GH6, BlackMagic pocket 4k, etc. But I'm trying to figure out if the Chronos mount is faulty, or if it just wasn't mentioned that the XL doesn't fit.

Has anyone else had this issue, and if you have made a speed booster properly turn and lock into the official Chronos M4/3 mount, did you use a different model? (0.71) or perhaps another way?

Thank's all -
