#1. "RE: Is Nikon's Price Differential between 800 & 800e Permanent?" In response to In response to 0
I don't think you can compare the D800/D800E price differential to earlier models. That is because except for one performance difference, they are the same model released at close to the same time. So as time goes on and prices drop the price differential ratio may stay the same. That assumes that both models stay current. In the case of prior models you were comparing a current model with one that was being replaced. So the replaced model would drop faster than the current model. An example would be the D3 vs the D3S. You really can't compare them.
Another scenario would be if Nikon announced they would discontinue the D800E but not the D800. In that case the D800E might actually increase in price for a time and the price differential would increase.
