Rick, rule of thumb for MFT mounts is 2lbs max for an unsupported lens. That said, I would support any lens heavier than 1.5 lbs, especially if it is more than 6” long. On the AF100, Barry Green, and others were recommending lens support for the Zeiss CP lenses, which are about the same size and weight as your APOs.
If you are going to add a Speed Booster, I would use additional lens support under your SLR Magic APOs, all you need is a rail baseplate under the camera and get the rail bracket for yiur Misfit Matre Box, to support the end of the lens. I use the Misfit mounted to the rails to support the end of my 18-50 PL Zoom, works great.
Cheers
