Although I'm not a Nikon user, I am disappointed to hear that the max flash sync speed for D4 is only 1/250. For such a high end body, I think a lot of event and wedding photographers could do with 1/500 sync. The 5DII only syncs at 1/200 which is a pain in the backside if you are trying to balance a bright background against a dark foreground. You have to lower your ISO/aperture and dump more juice out of your flash or carry an ND filter.

Yes, but thats flash dependent not camera specific. To get to the equivalent of 1/500 sync and dumping a 580ex at full power, will require a massively more powerful flash to do the same in high speed sync
That might rule it out for me for a while, (might buy a half decent car, for a change, instead)make shooting both simultaneously a bit of a problem
I've only speed read it, but one thing that stood out was that the control functions have a different layout to the D3/3s, which he says

[*]New battery type, more expensive, less capacity.
[*]No dual card slot (different card types).
[*]On the sensor - "we have an outstanding question at the moment of better, same, or worse than the D3s"
The Nikon D4 does accept the new type of ultra fast card though!
Maybe I will email him and ask what it is he's looking for?
they're now saying "one stop better than the D3s," but in a way
that is very couched. From what I've seen of images so far, I'd say one stop
worse visually, or back to D3 levels.
High ISO is a tricky subject. There are far more variables involved than
usually get talked about. One thing I see in the D4 samples is color
reduction, for example.
As to why the didn't say anything very specific, it's probably because it
isn't the clear win the D3 was at the time, or that the D3s was over the D3.
As you amplify low level data you get tonal ramps in all the color channels
that have gaps in them. And you might get noisy data, too. What you'll see
in pushing a camera up through ISO values is that contrast changes and color
fidelity changes. The D3/D3s are the best of the bunch at high ISO values,
and by a considerable margin.
No, higher dynamic range is a big can of worms. What most people mean by DR
these days seems to be the engineering definition: max saturation minus 1:1
SN ratio. Unfortunately, SN 1:1 is unusable. And DR is highest only on the
lowest ISO (or the real base ;~).
The D3/D3s have very clean high ISOs. The breakdown of data is very gradual,
and a lot of that has to do with the way the D3/D3s do the electron gain
prior to the ADC and apparently in a unique way. The D4 goes back to the
on-sensor ADC and traditional gain. The problem is that in very low light
(which is why you're boosting ISO in the first place usually) there aren't a
lot of photons being converted to electrons. When you push that count up via
a gain and then amplify it (for high ISO) bad things start to happen.
I give up, the dude just don't get it.
As for the comment about not having to change lenses in egypt, well I guess you've found the worlds first 10-500 1.2 lens with pro quality optics that can do everything. Congrats.
(why don't Nikon just make one lens anyway????)

chuffed by that alone.
Bet that's funded/supported by Sony who are looking down the barrel of a new betamax debacle.
C'mon Keith post some samples, even the box looks good!!
Why do you need to charge it fully?.....I have never understood that.

With all the new canon's and nikon's about to hit the shelves we need a new thread "Show us your shutter count #1 image"
