Q: 1. Would these work for video on a Sony FX6 with Rokinon glass? The lens is 100% manual, so no loss of function to worry about.

A: The FotodioX extension tubes do work with the FX6. If you're using manual lenses it should work fine.

Q: 2. Does it make sense to combine an extension tube with a macro lens (OM 5 + Zuiko 60mm macro)?

A: One can use extension tubes with Macro lenses to get even closer. This is something that can be effective. But the FotodioX Macro Extension Tube Set for Micro Four Thirds (MFT, M4/3) Cameras: for Extreme Close-Up Photography are manual extension tubes only. They would not allow for any focus or aperture control when used with the Olympus M.Zuiko Digital ED 60mm f/2.8 Macro Lens, and so would not be a good combination. If you want to use extension tubes with that lens, instead get the FotodioX Pro Automatic Macro Extension Tube Kit for Micro Four Thirds, BH #FOMCRMFTAFKI (https://bhpho.to/3IlwVeY).

Q: 10. Will this work with the Sony a7III?

A: Yes, the FotodioX Macro Extension Tube Set for Sony Alpha E-Mount Cameras: for Extreme Close-Up Photography, B&H # FOMACROTUBSN, would be compatible for use on the E-mount used on the Sony Alpha a7 III Mirrorless Digital Camera. Do note that the above are fully manual extension tubes, as there are no electronic contacts on the lens to transmit electronic information from the lens to the camera. As such, you will have to focus manually, as well as set your exposure manually. You also would not be able to control the aperture of the lens, so you will have to use the camera in either A (Aperture Priority) or M (Manual) mode.
