Excerpt: As good as the D3s for low light photography but with a little extra resolution and improved AF in low light. I bought it for low light work, and apart from the D3s there isnt another DSLR that can match it. I just wish it was smaller, like the D700, I would sacrifice some FPS and movie mode for size, then it would be perfect.
Excerpt: Nikon did well with this proprietary sensor - Color and tonal transition a definite step up. Should we have to pay the high price for 100% dependability? No. Is it 100% dependable? Yes! 16MB is fine for my work - Corporate event, portrait, travel and product/still life photography. Beautiful refined body and ergonomics. Problems: The separate XQD card and reader is a hinderance.
Summary: I jumped from D80 to D4. I am not a pro photographer but definitely serious one. Just wanted to share my opinion in using this camera for first 48 hours of using it. Biggest surprise was it feels really light in your hand for the size of the body. Before purchasing this I had concern of its weight but I am totally satisfied with its weight distribution in my hand. A pleasant surprise. Great camera in low lighting something I need more than anything.
Summary: Everybody seems to praise the D4 over the top, so why only 4 stars from me? Simple put: for six grand, I expect a camera that is perfect for the current state of the art. The D4 is not. I agree with most of the positive aspects and won't repeat them here, so here are my 10 shortfalls from "perfect". 1) The ISO performance is *VASTLY* exaggerated. ISO performance is 1 to 1.5 stops better than the D700, which is 5 years older than this camera.
Great for low light, not so happy about the new memory card coming

Summary: My Lightroom 3 & Adobe Camera Raw CS5.1 cannot read the raw file created by this camera, and both software programs are up to date. I bought Adobe Photoshop Lightroom 4 Upgrade and it can read the files and convert them to DNGs. I also just found out that Photomatix, the HDR software does not support these raw files. I purchased my D4 for the low light capability.
Excerpt: I had the possibility to compare today my D3S with the new D4, I made several pictures with each camera in low light conditions with the 24-70 lens fixed at 2.8, all the settings were the same, ISO where going from 1600 to 204800. The results were in favor of the D3S, the Nikon responsable told me that this is due to the sowftware which is not the definitive one.
Summary: It all began for me with the D300, then the D700 to step into Full Frame. And at last the D3s for Mega ISO with little noise. And thus far we have the D4. With a price drop of over a grand in the last year I took the plunge thinking the differential in price might be worth the differntial in performance over the D3s. Yep, absolutely And going to F8 for autofocus for me is a big plus for Birds and Wildlife.
Pros: Bright LCD, Comfortable Controls, Easy To Use, Fast Shutter Speed, Great Image Quality, Strong Construction
