Gionni Dorelli: Worked with an A99 yesterday. If you do not need the resolution of the D800 all the times, the a99 is simply the most complete Dslr camera at the moment.The EVF is just a joy to use and it does not hinder my way of taking photos at all. After a few minutes you would just forget it is an EVF instead of an ovf if wasn't for the wealth of informations that are displayed on it.
The only way I could buy a Canikon again, it would be if Sony stop making these kind cameras.I'm some what old fashion on the way I use cameras, but the A99 just feels natural to use.
Oh yes, and it's not a movable part anymore, prone to wear and tear, and it is the key to offering video capability worthy of the name, and above all, the images produced are just as outstanding as with a similar camera with old fashioned flip-mirror. When putting prints side by side, no one will be able to determine which one is taken with which camera :-)
