la question a été posée dans le Forum de DPrevieuw:
"Most likely means the version 2.0 firmware for the D2H that changed a few things to make it more like the D2Hs (like FW 2.0 in the D70 did in relation to the D70S).
Loading D2Hs firmware onto a D2H would be a very risky enterprise and would most likely break the camera- they use completely different image processing electronics inside, Different LCD screens, and so on. "
The outside differences are an S. Inside it's like a D2x wired up to the 4mp sensor
