              I would like to respond, I have been shooting full manual mode with 2 Sony a99's for some time, they are everything the good reviews claim. I just got a Nikon d800 and I think I woke up in a foreign country. I think the D810 is significantly more capable, but so far incredibly difficult especially in regard to the so called live view - with Sony you see exactly what the image will look like as you make adjustments, and with Nikon you have no idea what is happening till after you take the shot and review the image. I switched to Nikon on the advice of a photographer who thought I needed to step up my game, right now I have abandoned my plan to sell off my Sony's until I learn this new "language" and maybe never.
              You can't go wrong with the Sony A99 and Ziess lenses, it is an easy to learn system and gives you incredible images.

              Why Ronny? I'm considering buying one, leaning towards the D800 currently. Thanks
