I've spent the better part of 30 years in film doing Light Commercial/Portrait/Landscape work with mostly Mamiya 645 and RZ67. At 66 the transition to digital has been daunting to say the least. I started with a reconditioned D2 then a new D7000. I feel confident with both now but still dazzled with the diversity and perplexity of digital post processing! I want to expand to full frame and was about ready to pull the trigger on a D800 when the opportunity for a slightly used D3x came to me. The D3x is roughly a thousand dollars more than the 800 and I guess my dilemma is: am I really missing out on a lot other than megapixels, I realize the 800 has a technology advantage but many of my professional friends are dedicated to their 3x's, and having large hands the 3x fits better and has a much more secure feel. Any insight or opinions would be greatly appreciated as I try and re-invent myself for the third and hopefully last time. Thank you.
