Aaron, hard to say about the dynamic range, yet the sunset photos I thought came out pretty well for a single shot.
Shooting the D3x was such a pleasure, what a great camera, but to get the most out of it I found I was shooting the D3x as if it was MF, same exact setup manual focus, (yeah I miss live view for focusing) tripod, MLU, remote release etc.
For me, would I go out and buy a new MF system no way, unless I was a pro and made money with my camera, just way to expensive. I looked for over 8 months pondering wether to go MF and always came up against the $$$$ wall. When I found the H3D39 for 6500.00 I couldn't resist. So I took the plunge. After selling off all my Nikon Stuff, the conversion from 35mm FF to MF cost me about 1200.00 so for me I am happy.
For a while i was looking at the 22mp MF solution, but after giving it serious thought I felt if I were to make the jump I needed to go 39mp.
The million dollar question.... Am I happy, yep so far so good. Would I do it again for the price I paid yep, If it cost me another 5K probably not.
Do I miss my PC-E lenses.. SURE DO. I really liked using them. Maybe one day I can save up enough money and purchase the Hassy T/S adaptor.
In the mean time, I use my Multiflex / Cube knockoff and tilt my camera up and down.
