Thanks for the explication.The Digiloyd review appeared at the same time as Ming Thein's review, so it is not clear what was the production level of his lens. Both were done before deliveries to regular customers were permitted. Also, AF tuning is done in DSLRs with phase detection sensors which are separate from the image chip. Contrast detection AF doesn't have that separation -- the lens is adjusted to maximize contrast in selected locations of the actual image -- so as far as I know there are no cameras offering AF tuning when they work this way.

But are you sure about the timing? Chambers analysis started yesterday and I remember that he did not get a test copy from Leica ...
