Err, if the pixel is dead then it isn't sending any information
back to the image processing circuitry (hence either a white or
black dot), if the lens was to fault the problem would be
intermittent as focus and iris settings would mask the optical
damage, one would certainly get some sort of colour/movement
information being processed - I actually own a telephoto lens
from my old 35mm SLR days that had a ruddy great chip on the
outer lens but the damage is not noticeable on most negatives!
