I'm impatiently awaiting side by side photo comparison with D800. From the point od view of physics D600 could have smaller noise than 36Mpx D800 sensor.
Also from the point of view of image processing and data storage for me 24Mpx is better than 36Mpx of D800.
Do you think D600 will be in the shops before Christmas?
I made little experiment with Photoshop Unsharp Mask tool to mimic D800E image from D800 image. And even in the horrible conditions described on my page IT IS POSSIBLE!
daiviet: I am rather bemused by the preoccupation about noise and ISO settings evidenced in this discussion thread. The way that sensor technology is evolving along with image processing software, I believe that ISO-less photography has arrived. On my Nikon D90, I have shot pictures at ISO 3200 that are perfectly usable after processing through Lightroom 3.6. I always shoot with Auto ISO turned on, and so far it has worked for me. I expect the D800 will deliver a significant improvement over my D90.
Both have similar pixel pitch, D7000 has some years of technology developement more. By the way pixel pitch of D800 is similar to pitch of D7000, so I think that its noise performance could be just little bit better than D7000.
Physics works, and that's why I think, it will not deliver significant improvement of pixel noise over D90. D90 has sensor pixel pitch about 55um, D800 has about 48um so the pixel area of D800 is only aprox. 76% of D90s pixel area. Yes the CMOS technology have improved from the time of D90, so I think that the noise charcteristic of pixels would be simillar on both sensors.The only significant improvement is the image resolution of D800. It means that the same pixel noise will be much less significant on the same printed picture size compared to D90 picture.
munro harrap: The D4 gains improved aperture control in movie mode, with the addition of 'Power aperture'. This simply means that the user can adjust the aperture while recording video in the A and M exposure modes. It's also possible to set the aperture much more precisely in video live view mode before recording starts, in 1/8 stop incrementss using the Pv and Fn buttons on the front of the camera. In principle this should allow more exact matching of recording brightness across multiple camera / lens combinations.
If this applies to the D800 as written above, my correspondent is correct and we shall have this same essential faculty in the D800, but it is not categorically stated as such by Dpreview.....
Yes, it has the same functionality of Pv and Fv buttons, I have seen it yesterday on live demonstration. The efect of this aperture setting is much more smooth than setting by the normal aperture wheel, but is stil faaaar away of smoothenes of aperture setting on even amateur videocameras. But the effect of live DOF resetting during the shot on the FX sensor size is simply GREAT!
...continued: But the main problem (at least in this preproduction camera) was the noise. Hi2 setting is realy unusable (and also the file size of such images is huuuuge, which tells the true story about the noise). Hi1 and ISO 6400 is usable only in the critical situations where very bad image is better than no image. From ISO 3200 downwards the images on the display seem to be pretty OK. It is not possible to reduce resolution in the RAW mode, but only in JPG modes, so the noise reduction using the resolution reduction is possible only on the JPG workflow. Even Nikon demonstrator told us, that real noise of D800 on pixel level is aprox one EV worst than the D700 noise (for example 3200 noise of D800 is near to 6400 noise of D700). On the other hand he told, that the print of the same size has one EV better noise from D800 than from D700 thanks to bigger resolution.My conclusion from todays demonstration is, that I personaly shall wait for the D700 price drop and buy D700.Jakub
So today I had the preproduction D800E in my hands (during Nikon days in biggest photo store here in Prague). It is realy beautifull camera with very sofisticated design up to smallest details. I was allowed to take pictures inside the shop and play with the camera settings, but it was obviously not possible to take the pictures with me nor show them on the full resolution display (there was only HDTV with HDMI connection, so we were looking only at bigger copy of camera back display). Even in that simple configuration it was possible to induce moire very easily and my opinion is, that the E version is realy useles for the majority of normal photographers. It is much easier to sensitively sharpen the small percentage of D800 images which would gain from the D800E in postprocessing than to remove moire problems from the majority of D800E pictures taken in non natural sceneries. ... to be continued
wil13jak: It has (I think) been eluded to that the cf cover and the rubber grip glue are bad on Nikons???? I have owned a D1, D2, D3, D700, D7000 over the years and currently and have never ever found either of these as problematic and I use my cameras alot and at times I'm not the most gentle. Hmmmmm
I have D70 and D200 and on both cameras I have serious problem with the rubber grip glue. I'm trying to take care about my cameras as much as possible however the problem started on both cameras after aprox. 6000 shots taken. May be it has something to do with agresivity of photographers sweat, but I thing this range of cameras could have it solved.
To dpreview: When you do the full review (and I hope, that you will do it ASAP), could you please compare shots on high ISO (6400) in full resolution with let's say resolution 4608 x 3056, which is comparable with D700 full resolution (4256 x 2832) with the D700 shots on the same ISO?I think it would be interesting for many people and it will either prove or not if mathematical combination of aprox. 1.777 square pixels into one resulting pixel makes the same noise level as sensor pitch increased aprox. 1.3333 times.
Megapixels, megapixels, megapixels :-((( I am waiting for this camera from the moment D3S apeared and there was hope, that Nikon shall upgrade also D700 to D700S (with video capabilities). I was waiting because of fantastic ISO range of D3S. Even D800 has nice ISO range, but I am afraid of much worse noise parameters with 36MP sensor. It's a pity, that Nikon doesn't plan to produce two variants, something like D800X and D800S.
