Today I picked up a DMW-LVF. Everything worked the way I expected it to with one exception. I had the grid on and when I panned the camera quickly the refresh was so slow that the lines of the grid broke up into Red Green Blue lines. This was most pronounce if the camera rotated slightly in relationship to the light path to my eye. Once the pan was over it did behave. I have seen this effect before on cheap video monitors. Is this a normal abnormality with this peace of equipment?
