I have used it for about 2 years (got it right after it came out). I made a mistake of being in a bad tripod (low end, cheap stuff) and moved to an RRS TVC24L. Now, I find that it satisfies almost all my needs and more. In fact, it is a lot for me and I am learning new things every time I use it. I know that it is not for high speed photography (sports etc). Since I am in landscape, it was fine. I did some whale watching with it in Monterey and it was superb with a 70-200mm. It looks like I can live with it for about 10 years without problems (unless it breaks down or I exceed 200k shots). Wonder if any of you feel that there is a great need to have a "greater" camera than this. I agree that that I am not in video and it does not have 4k etc. Also, it does not support the newer SD cards UHS-II. Any thoughts on this?
Carlos -- Forget the price. If you don't need a fast frame rate, there is not a better camera than the D800. Maybe a medium format 50+mb camera -- but in the 35mm shape/size environment, I think the D800 is the top shelf now.
The future for cameras is to look at what top photographers are doing. They "find a way" and in turn prove the need. Camera companies follow.
With a D800 it can be comfortable to feel things are fine. Maybe you will stay where you are but maybe you'll get some desire to do something new that can't be done another way today.
Being comfortable means you don't lead the parade. It's Ok not to be on the front edge of technology, but you are today. The problem is you just may see something that gets you going and you suddenly realize it. You'll spend money and it all starts again. You can't know today, but then again you don't have to. You just have to wait and enjoy the good times while you can.
Things will change a lot in ten years just like they always do. Photography has been a technology leader since it's earliest days. That has never changed and probably won't. Money says you'll make a change inside of ten years and be very glad you did. Might be gradual or all of a sudden.
I bought a used d800e about three weeks ago, it had about 13,000 clicks so just barely broken in. I had a d4 and sold it after I got the d800e. The 800e suits by photographic needs better with higher resolution, excellent af and very good low noise levels. I can crop a lot more with the d800e than with the d4. I have the battery grip using aa batteries and can get around 6 frames a second which is plenty good for my wildlife photography.
The feather detail on birds is much better than with the d4. I am completely happy with the d800e and now have the money after selling my d4 for the update of the d800e if it proves out better.
