Electric interference of one kind or another is of course the likely culprit. I am just not sure the spring has much to do with it.

That's something that I hadn't considered. The lens does draw power from the camera (believe it or not, the lens itself is apparently a little computer -- probably ARM based -- with its own integrated EPROM or flash storage). I wonder if it fluctuates its power draw (ever so minutely, perhaps on a particular frequency calculable based on band size and sensor read-out speed) such that the A2D processing on the sensor is affected.
