I have a JVC RS4810 and the len zooming works great. I've got it calibrated so both aspect ratios I use have similar brightness. I even have a third one programmed for something between 2:35 and 1:85. The only issue is the memory "forgets" sometimes when you change aspect ratios for zoom - you have to slightly re-shift the image to center it exactly on the screen when this happens. I always make sure I check before watching a movie.
