Yes, I have my D300 and D3 and new lenses. No, I don't have much to say about them yet, unlike most Internet sites.Yes, I'll eventually review them. Yes, I'll have eBooks on them. But no, I don't know when either reviews or eBooks will be available.
Seriously, folks: it takes an awful lot of testing and use to flesh out the pluses and minuses of sophisticated new cameras. I've been amused as I watch the net chatter about these two key new Nikon products. Half the folk that should know better are gyrating on their postings about the cameras (first it has problems, then they figure them out, then they discover something else that stumps them for awhile, etc.) while the other half have simply made a blatant pronouncement (e.g. "best DSLR ever" or "not substantially different than a D200").
Personally, even in just the modest amount of use I've been able to perform while traveling, I've noticed a lot of small things that require a great deal more investigation before writing about them with authority. I've no doubt that these two cameras push Nikon's DSLR capabilities into new territories, but without being able to say exactly how far we've come from where we've been, I'll simply stay quiet. Okay, not exactly quiet.
