Fernando, Being a cynical Brit, I would say the reason it doesn't work is to force us to buy AF-D lenses. The old FA could do shutter priority with AI-S lenses, but AF cameras cannot?!! It's all about flogging product- the colour meter has been championed by Nikon in their ads and if you want to use it, you better change your lenses too. ------ Incidentally, Nikon ran a nice ad campaign in U.K last year, showing Nikons being used in films at the cinema.Things like Dennis Hopper with a couple of F's in Apocalypse now etc. Just thought I'd mention it as it came up recently.
