I suspect the dust-shake glass is sitting on top of the distorted neoprene seal/adheasive left after the filter removal (thats the one negative thing that happened, the filter broke, but I dont care), hard up against the glass stack retaining clip by pure luck. I understand focus has something to do with the top glass layer (which seems to explain why it still works, despite the filter removal, I guess if I had done it properly, the shake glass would have been sitting lower), although I dont know why, I thought auto focus relied on optical artifact edge transition difference, cant see the importance of the glass its self.
No, I didnt take pics of the mod Eric, why would you need it, yours is done ;-).
