The peripheral aberrations in the Noctilux are so bad that it causes white lights on the wall to separate into primary colors when you point it at it. You just THOUGHT there were colored lights up there. Bet if you put the lenscap back on the light would revert back to white ;-] Well, it sure looked like a prism effect. I use the Noctilux in some situations (usually inside under dim, artificial lighting) mostly in B&W but I really do see oof light sources markedly coma shaped out towards the edge of the image. It doesn't bother me, it's just the price we pay for speed. The image center, in focus, is mostly aberration free with just a little softening. I personally wouldn't want to have an f/1.0 lens that performed like f/5.6... too brutal... JB
