We are using a 12-100 olympus lenses.

We just can conect the focus demand.
All the equipment is new.
Hope that you can help us.

The Oly 12-100 doesn’t have a servo zoom.

Good Luck

There are only 4 MFT lenses with power zoom:

Panasonic Lumix G X Vario PZ 14-42mm f/3.5-5.6 Power O.I.S. Lens
Panasonic Lumix G X Vario PZ 45-175mm f/4.0-5.6 Zoom OIS Lens
Olympus 12-50mm f/3.5-6.3 ED M.Zuiko EZ Micro 4/3 Lens
Olympus 14-42mm M.Zuiko f/3.5-5.6 Digital ED EZ Lens

As an alternative, you can use some Canon EF mount lenses with Metabones adapters:
