Lossless compressed is what I do now already for years and will continue to do. Why would you shoot uncompressed if compressed can be lossless? It is for sure better than jpeg. For the time being DX mode would be my eco-mode, but obviously only in cases where I will definitely not be shooting potential 'masterpieces'.
In the meantime I can eliminate the word 'almost' from the title of this thread. I bit the bullet, the beast is ordered and can be picked up tomorrow. Already downloaded the ebook on Mastering the D800 too and about to order a new pc as well. The pain in my savings account is serious, but hey, you 're hooked or not and the pleasure while opening the box, well, that will make me happy as a kid unpacking his present from Sinterklaa . Comes with a nice 16-35mm too. Will share a picture shortly.
