Hi, I'm using F100, D200 and D300s cameras. I have found an offer for a demo version of D800 (18.000 clics and 1 year full waranty) for the half price of a new D810. Yes, I have read a lot about these two cameras and different comparisons. I would be glad to read about your oppinions regarding the ease of use of these cameras with old MF (manual focus) lenses. From my film times I have quite some MF and older AF lenses (and also some accessories) I used and still use with my F100. Would it be a mistake buying a camera (D800) if a new updated model (D810) is for sale now ? Should I wait and save some more money for the new model? What do the differences between these two cameras mean in practical work? I just looked at the D750, but is about 50% more than the D800 offer and besides, the buttons and the layout differs quite a lot from my current cameras and I also like the built of the D800 similary to my F100. I know I don't actually need the whole 36Mpix but I can crop the photo if necessary. Any help would be much appreciated. Thanks, Miha.
