Sssstttt.... don't say that too loud. You might wake-up sleeping dogs. I do agree with some of the remarks that no 35mm lens can compare to the Digitars. I have been toying around with my X-act and Schneider Digitars this weekend. I thought my Hasselblad HC lenses were pretty good but the difference between those and my 90 and 120 digitars was very noticeable.
Before getting my P45(+) and the ALPA SWA with the Rodenstock HRs and the APO Digitar 180mm almost two years ago, I did a great many comparisons between (then) Hasselblad H2 (and the lenses), the Mamiya 645 AFD II (and the lenses), the Cambo Wide DS and the ALPA SWA each with the digitally optimized Rodenstocks and Schneider lenses, using Aptus 65 and P45 backs:
The advantage of the ALPA (and almost as clearly the Cambo) was very obvious.
For my landscape work, nothing beats my current system. And although the announced P65+ seems tempting, the deal breaker probably will be the limitation of shutter speeds to a maximum of about 30sec to 60sec.
The Nikon D3x (or ANY other 35mm "full frame" camera) are great tools but are NOT playing in the same league resolutionwise and also considering their dynamic range.
They got other strong points (e.g. frames/sec, autofocus, display, live view, Menu options...), which of course would be a welcome addition in the world of MFD.
