Secondo Dx0Mark la D4 le busca nello sport dalla D3s e nella gamma dinamica dalla D3x...

Hi All
I got my D4 last week (NPS member) and shot 2 weddings over the weekend.
D4 is better in ISO – in real life – then the D3 or D3s. The noise value in D4 at 12800 is same as D3 at 6400 BUT! The contrast, dynamic range and sharpness it retains at that ISO is incredible.
I read a lot how people care above specs and what not, but thats not all that.
There are another “issues” that noone talks about and i give you some insights.
Matrix metering of D4 tends to overexpose in dark situation by about half a stop, hence brighter image, hence less visible noise, but still an amazing contract DR and sharpness. A little bit of cheating i think…
The new focusing mechanism… What a beauty – this only would make me (and made me) buy one.
No-one I see mentioned anything about color rendition. The new D4 is more vibrant, however tent to have slightly yellowish/greenish tint… Quite off-putting as in some situation as the skin tones gets “pale”.
My D4 even had an issue with LCD brightness not displaying correctly! So some of my images ended up underexposed by a stop or so…
But Nikon reinstalled the firmware and this issue is now corrected, but lots of my photogs friends, that got the d4 experience the tint issue and I suspect it is something you will hear about more and more in a near future…
If you believe that D4 is only a minor upgrade to D3(s), In my opinion you are wrong. It is a better camera in many ways.
Now i gotta go, my D800 should arrive any minute and i will be happy to comment about it after the weekend, once i experience it in real situation, rather than speculate based on specs and some reviews…
