After trying different zoom controllers from Manfrotto and Fujinon for my HPX370,
I decided to try Varizoom. I could not be more pleased. IMHO the Varizoom zoom
controller allows smoother more accurate control, I was so impressed with the zoom
controller I ordered the Rear Focusing Control and I was not disappointed. Now I can
control the zoom and focus from behind the camera. I have found that I eliminated
camera shake when I focus or zoom the lens, this is especially noticeable zoomed way out.
