Focus Problem With Dome Cover

I hope to know correlation between transparent dome cover[Bubble] and Zoom focus.

For example, Zoom module performance likes zoom-in focus (far focus), color reproduction may be controled according to transparent bubble, is it right? A high magnification zoom PTZ camera with dome cover is out of focus. ( x30 2MP PTZ speed dome )

can you elaborate on this?
