Upload & Sell: Off
I purchased a D800 when they came out. At ISO 800, the noise per pixel was horrible, and at high ISO's, I just did not like the results. I had bought three high end Nikon lenses, and the resolution was great outdoors on a bright day, and DR in that situation let me raise shadows. But, since most of my use was in low light at extreme high ISO's, I turned around and sold it after a month. The camera was still difficult to find in stock, so I netted what I had paid. I had kept my camera gear, I was shooting the Nikon alongside my 1DMK IV at ISO 12800, and much preferred the Canon images.
There was, of course, the ergonomic issues, but the weird menu is something I'd learn in time and be comfortable with. Then, the 24-70 f/2.8G I had had absolutely horrible CA's. I had to shoot wide open in the dark, and that made it so bad that Lightroom could not correct enough to get rid of it all. I have learned my lesson, the reviews don't always cover the way you use a camera. Oh, I also use live view a lot for product photos, but Live view on Nikon cameras was a bad joke.
