Got it. That's amazing.
Since I've switched to seriously considering the new Sony 4K all sorts of questions are popping into my head, and now this one:
Since I zoom so often and adjust the image to new sizes within my 4-way masking, the JVCs have worked amazing. First, they have a nice lens pattern that comes on for zooming, which outlines all the common aspect ratios.
Secondly, the zoom control is fine enough - though not perfect - to pretty easily nudge the image into place, both in terms of the zoom control and the vertical shift control.
How sensitive or finely controllable is the zoom on your Sony?
