Lenses for Studio Camera 4K Pro G2

Hello,

i bought a Studio Camera 4K Pro G2.
I'm now looking for lenses that would fit the camera and have optimal compatibility.
I would like to use the ZOOM function and the autofocus, although the autofocus is more important.
For example, Blackmagic recommends the Olympus 12-50 mm f/3.5-6.3 ED M. Zuiko EZ Micro 4/3 lens.
That would have wide angle as well as a bit of telephoto.
However, the light intensity is only 3.5-6.3.
Are there no other lenses that would work?
Sorry, but I'm a complete beginner with the camera.

Thanks

Armin

These are the 4/3 ones I use with my ATEM:
Panasonic Lumix 14-42 PZ and 45-175 PZ
Olympus 14-42 EZ and 12-50 EZ
