If you wanted to use a certain lens, but needed to tighten up the shot a little, would zooming in farther on the GG lose any quality? For instance, My 35-105mm zoom lens (which I only really use for the macro). I can focus pretty close, but the frame is always too wide. Could I zoom in on the HVX? Or would it effect the quality?
Does zooming in on the GG effect quality?

Depends on the adapter. On my Letus Extreme I can zoom in and out a small amount and still have the image remains sharp. On the Letus Ultimate I can zoom in practically all the way and not lose quality. Some adapters if you zoom in too far you'll no longer be able to keep focus on the GG.

sort of expanding on what Huy Vu said there, once you zoom past a certain point you cant focus closer up. I know on the DVX you have unlimited zoom from 00 all the way to 99 which is ideal for an adapter IMO because you can use that macro feature, but once you zoom past 70 the focus wont let you go below 36, I believe, and you are stuck with that unless you buy an achromat or macro lens, so I've been told.
I'm working on my own vibrating GG adapter right now and had to deal with that problem as well.

Zooming in typically has the following effects:
1. If grain is an issue, it will get worse as you zoom in. This is simply becasue you're increasing magnification.
2. If edge falloff is prevalent, then it usually gets worse as you zoom in. On cameras like the little HV20, you'll lose nearly a stop of light at the edges at full zoom. The waveform monitor on an evenly lit surface goes from a straight line to nearly 20 IRE down on the left and right edges.
3. Unless your camera lens is constant aperture, you will lose a bit of light by zooming in too.
4. In terms of edge softness, every camera has a sweet spot with every different make of adapter. This is generally in the area of 50-60% zoom and f4 on the video camera but will of course vary depending on the camera and adapter.
