DP1 vs DP1s vs DP1x?
dp1 -original red reflections from sun ,discharges battery when not in use.
dp1s different anti-reflective coating less red reflection from sun battery does not discharge when camera off.
dp1x added analog front end.
1:- not all DP1s dicharged the battery when not in use , neither of mine did/have and one was from around launch time ..
2:- the red-reflection cure of the S added its own worse issue of green edges, diff being that the green edge issue was regardless of shooting conditions whereas the DP1 reflection issue only happened if you were silly enough to shoot straight into the sun (no foveon likes this full stop anyway , even the SD15)
3:- Analog Front end improved high ISOs (which were still poor but usable at 800 now) but the X`s real biggie was the massive speed increase when buffering files
