Does this camera have zoom in capabilities? I know the PV2+ standard camera works nice but has a fixed zoom ratio

The H3-3D is just a gimble to hold the GoPro line of cameras.

Great comment sureloch, anyone know if the camera that goes on this gimbal has camera built in zoom capability?

If you fly towards the subject you are looking at, yes, it will appear that you are zooming in.......

But to answer your question, No.
