LOL 5 years of technology gap and you want to compare them? In tech years, that's a lifetime! Are you serious? Processors doubled in speed as did memory etc. If that's your criteria then Nikon is absolutely scraping the barrel with a camera that 5 years too late. I can say that my old 1DsMkII had better resolution than the D3 but not the same DR whereby the 1DsmkII couldn't pull back 1.5 stops of highlights unlike the new 14 bit cameras. And the noise level of the cameras are close up to 800ISO while being 2 years behind in technology.
Yes, yes and sorta. I gave up the pro body cameras for travel purposes (as have many others like Eric). Along with it went super fast AF and battery life. I'm reconsidering the 1Dmark IV because of the low light ability of the 1080p and 10fps. My requirements however are not your requirements. I don't focus with AF in video as much as use MF, which is killer on most of today's housing LCD windows due to reflection.
To me it's pretty simple. If 2 cameras performance are close enough image wise but there's a 40+% resolution difference in stills and video (plus more video features) for one camera over the other, I'd choose the higher resolution, better featured camera. I'm also planted in the now. I don't know what camera is coming and I'm not about to wait in hope of features that may or may not be included. I get what is available NOW to satisfy my requirements now. If none of the cameras fit my requirements, then I either wait or change them to suit the cameras available. Either way, it's a simple decision based on my requirements. List your own requirements and then choose the camera that suits it closest.
"LOL 5 years of technology gap and you want to compare them?" : Yes, newer does not necessarily mean better. Now I am LOL.
"I can say that my old 1DsMkII had better resolution than the D3": >> Sensor resolution is not everything. If this were true people would have used Kodachrome25 exclusively in their 35mm cameras in the film era (within the production life of KM).
"My requirements however are not your requirements.": >> Key point which is VERY true!!! ![]()
for example your video requirements which are presently not relevant to me ![]()
"I gave up the pro body cameras for travel purposes (as have many others like Eric). Along with it went super fast AF and battery life": >>
AF is a major part of my technique without which I would not have many shots in focus. Absolutely NO room for compromise.
Battery life is a concern for me as I use my camera powered up for extended periods, e.g., 7 hours. I have used over 50% of a fully charged newer model battery (D3 generation) on several shoots.
I have packed two large D2 housings and accessories up a stream, but there are advantages to the larger housing as well (position of the optical axis with respect to the housing bottom)
