Chasseur d'Images published the full transcript from the Facebook Q&A session with Thomas Maquaire from Nikon France on the new D4 and D800/E cameras. Here is the Google translation (UPDATE: I got a better translation from a reader, thanks Mike):

Hello everyone, we are pleased to invite you to our first question and answer session live over the internet.
We have already received many questions and we will try to answer within the allotted time.
Notice that we will only answer to questions about Nikon D800 and Nikon D4.

Q: Is the D800E higher in sensitivity compared to D800?
A: No, the D800 and D800E both have a sensitivity of ISO 100 to ISO 6400 with two expandable levels (Standard ISO 100 to ISO 6400, range expandable to ISO 50 to 25600 equivalent)

Q: How many dealers will have the D4 in France?
A: The D4 will be sold exclusively in selective distribution which is approximately 80 stores.

Q: On the D800, are RAW file systematically recorded in 36 MPX or is there a setting to reduce the number of pixels, except using JPEG output format while still in RAW
A: The D800 offers 36MPX RAW files to give photographers maximum definition. But you can, in postprocessing, adjust the final definition of the image (JPEG only).

Q: What about video capabilities of D800: is there an autofocus? of what kind? how is processed subject tracking ?
A: The D800 features a new contrast detection AF (directly implemented on the sensor). It is available in AF Live View and video. It is continuous and allows subject tracking.

Q: Hello, the Nikon D800 and D4 form the new full frame lineup (FX format). However, someone switching to full-frame has the choice between a 36 Mpixels device, requesting high optical quality lenses and powerful post processing hardware to deal effectively as much of information, or a device admittedly high-performance but overpriced. The D700 realized this link between the ultra-versatile D3s and D3x dedicated to studio photography and large format printing lovers. How to advise someone who wants to switch to full frame? We must admit that the D800 36Mpixels is not easy to manage.
A: The concept of D800 is to provide maximum definition in a versatile package. The D700 remains in the lineup and would provide to photographers who do not need high definition a very affordable alternative.

Q: Hello. Could you tell us the difference between D4 and D800 in terms of extreme conditions resistance (high / low temperatures, rain, etc..)?
A: D4 and D800 have anti-dripping seals and a magnesium alloy body that allows use in extreme conditions. Although, even if no datas are provided, the strength and tightness of D4 were elevated to a higher level.

Q: A comfortable user of Capture NX have more direct interest to choose the D800 E version?
A: The choice of D800E must be done considering an expert approach of aliasing management, especially during shooting and in post-production. Nikon Capture NX is a post-production tools that can help you with.

Q: Positioning of AF points has been reviewed ?
A: Density and coverage of 51points AF system of D800 and D4 is identical to the D700 and D3 series. Gap of performance of the new generation AF is due to collimators sensitivity and Scene Recognition System that allows much finer acquisition and subject tracking.

Q: D800E risk of moiré also concerns video?
A: In imaging as on video, structure of the low pass filter of D800E can cause moiré. Definition reduction in video due to "downscaling" and video specific image processing should limit appearance of moiré in the image. Notice that video recording via HDMI output in a format such as Apple Pro Res optimizes post-production and thus the final image.

Q: Difference between the two D800 bodies ?
A: D800 is equipped with a low pass filter which is designed to disperse light rays to limit aliasing effect. Whereas the structure of the D800E low-pass filter have the same optical path but cancels the diffusion of light rays.

Q: Sound quality of the D800?
A: The D800 is built-in external stereo microphone input for mixing. A permanent audio level indicators offer visual confirmation of audio level and an external headphone jack enables you to effectively monitor and control audio.

Q: Hello, why USB3 port on the D800 while the D4 have only has a USB2?
A: The choice of USB3 port on the D800 is linked to high definition concept (36Mpx) and then the need of transferring files as fast as possible. The definition of D4 is lower (16Mpx), so choice of USB 2 was considered as sufficient. Nevertheless, the potential of D4 in terms of pictures transmission (Ethernet, Wi-Fi) makes it the body with most communication features of the series.

Q: Are there plans to update the D700 firmware in order to integrate part of latest D800 software features ?
A: The D800 is designed to provide the very high resolution. All software development is linked to this parameter. So D800 software is specific and cannot be applicable to other bodies like the D700.

Q: I understand that several formats are available on the D800 as the DX ... in this mode, what is the effective RAW image size (in pixels) ?
A: At DX format (24 × 16): the definition is 15.4 MPx is 4800 × 3200

Q: Which optical quality level is required to operate with 36Mpx of D800 ?
A: To enjoy the full potential provided by 36Mpx, useage of High-performance Nikkor lenses or latest high quality lenses is required. For example: AF-S 24-70mm f/2.8, or 35mm f/1.4 or 105mm AF-S VR macro ...

Q: Why the D800 is it not compatible with WT5 wireless transmitter module ?
A: D4 includes a pre-processing data chip (before submission to the WT-5) that helps increasing pictures wireless transfer speed. For space saving reasons, this engine was not integrated into the D800. However, the D800 remains compatible with the WT-4.

Q: Why button illumination function of the D4 is not implemented on the D800? Maybe a further update ?
A: D4 has been designed to work in extreme conditions, including low light (or night). That's why we integrated button illumination function. D800 concept is high definition so it was not considered necessary to implement it.

Q: Is the D800 better than the D700 at low light iso (ex.3200 and 6400) at same image size (without benefit of D800 higher resolution) ?
A: D800 sensor choice and applied post-processing allows image results equivalent to D700 at all sensitivity presets.

Q: Is selected D800 AF-point moving when changing portrait / landscape as on the D4? If not, linked to extra grip useage ?
A: D800 does not have all the ergonomic modifications of D4 as the dedicated AF command or AF toggle when switching from a portrait to landscape.

Q: Difference between D800 and E made by internal software and / or firmware ?
A: Same firmware.

Q: You indicated previously that the D700 remained in the lineup, so we should not consider the D800 as his replacement
A: Yes.

Q: Are crop formats x1.2, DX and 4:5 available in RAW (NEF) ?
A: Yes!

Q: Will it have other manufacturers than Sony providing XQD memory cards ? and is it planned to propose an upgrade to avoid having two types of cards in the D4?
A: Currently only Sony plan to sell XQD cards. No hardware update is planned about D4 to offer 2 slots of the same card type.

Q: Is LR4 able to reduce moire of D800E ?
A: Adobe have to provide the answer

Q: D4 would have a better noise result at ISO 12800 than D3s ! What about exactly?
A: Improved definition and noise management of D4 offer better performances than the D3 series.

Q: I saw that the D800 has a built-in HDR mode. How does it works ? What are the fine tuning options ?
A: HDR allows capture of two images in a single shutter press. Exposure Gap between the two exposure images can be set from 1 to 3 EV.

Q: I am going to purchase a D4 and a D800E but already some pro-agents resellers in Paris alert me on possible delivery delays ! What exactly?
A: D4 will be sold from March 15, 2012. D800 from 22 March and D800E from April 12.

Q: Are there significant advantages to use stabilized lenses with D800 36Mp sensor to reduce micro-shaking (like 24-120 f4 instead of AF-S 24 -70 f2.8) ?
A: To reduce the micro-vibrations, the shutter is equipped with an anti-vibration system.

Q: Why D800's frame rate is limited to 4 or 5 frames per second?
A: Frame rate is directly related to amount of data to process (4 fps in 36Mpx or 6 fps in 15Mpx DX format with battery EN-EL18).
Moreover, buffer of D800 allows more continuous shoots than D700 despite a 3x higher resolution.

Q: Is megapixels increase done in detriment of sensor sensitivity? Would it be a more valuable to combine technology improvement with lower resolution (and so lower density)?
A: Intrinsic sensitivity of the sensor is directly related to the density of the photosites. However, the positioning of D800 is to propose a highest definition as possible. The sensor design and image processing achieves sensitivity levels already very impressive.

Q: Compatibility of D700 battery with the D800?
A: No. The battery of the D700 and D3s no longer meet the new standards applicable in Japan. Nikon used same battery for the D800 D7000 and designed a new battery for D4.

Q: If using old non-AF lens for example, the 36MP sensor of D800 will be a disadvantage or an advantage?
A: The latest NIKKOR lenses receive optical designs that have evolved over older lenses. The gain in resolution is related to these developments. So greater benefit with the latest lenses.

Q: Why did not you integrated GPS in D800.
A: The concept of D800 did not need to embed the GPS function.

Q: Maximum recording speed of videos recording with the D800?
A: In card recording, up to 24Mbits per second. In HDMI, rate related to recording format defined on recorder.

Q: Crop (x1.2 / DX) in the viewfinder? Grid ? Shaded part?
A: Unused portion is grayed out but still translucent.

Q: The sensor is it backlit ? Manufacturer ?
A: The sensor design was done in cooperation with a partner company. Manufacturing is done by this partner company.

Q: Do you plan to release an update on the D800 to implement 16/9 format directly in the viewfinder? This will simplify the frame slide show on TV screen.
A: In theory, no.

Q: D4 pre-orders recorded to date in France will be satisfied on March 15? (Congratulations for these wonderful bodies !).
A: Thank you! To answer you: no, pre-orders exceeded all our expectations.

Q: Do you consider D800 as a replacement of D3X?
A: No. D800 positioning is different than existing D700 or D3x bodies.

Q: Hello, what is your target of D800, knowing that the sensor 36Mpx away significantly from its little brother the D700, which one of the selling points was: little MP to a size of photosites more large, resulting in better sensitivity. What about this statement with this new 36Mpx?
A: You are right, the D700 offers little MPx for high sensitivity (reportage, low light ...).
The D800, on the other hand is for those seeking an extremely fine detail rendering (landscape, architecture, fashion, portrait ...)

Q: Is the D700 will be discontinued??
A: No, the D700 remains in the lineup.

Q: Does Nikon School videos will be updated quickly to unleash potential of D4?
A: It is our practice to change our courses according to demand. I would not fail to note your remarks to the Nikon School.

Q: D800 HDR output file format a RAW or JPEG directly?
A: JPEG only.

Q: Capture NX will he provided free with the D800 as in Germany?
A: Only with D800E.

Q: Are there any hope for progress on the side of the dynamics in the D800/D4 from generation D700/D3?
A: Yes! Dynamic range and color reproduction is improved.

Q: Some photographers have they test the D800? Or can we see photos taken with the d800?
A: I invite you to visit our Flickr:
