Re: MF adapter / Sunagor lens.

I use an OM-EF adapter with a helicoidal or focal reducing EF-MFT adapter for my OM lenses. (All from the far east via E-bay)

This works well using the lenses as fully manual, and the helicoid boosts the macro capabilities while still allowing infinity focus. I wouldn't expect either of the types you've found to offer any degree of automation so either should be equivalent.

OM lenses have a DOF preview button on the mount to shut down the aperture, but if the adapter closes the aperture on mounting the lens it's not really an issue focusing with the lens shut down with mirrorless cameras. (Unlike on A SLR where the viewfinder would get too dim)
