Well, my sister blew my mind this morning with a D200 as we all opened the Christmas loot. I've only barely started to play with it but . . . WOW!!! definitely heavier than the D70, about 3.5 pounds with lens vs. 2 and change for the D70. Has a nice heft to it, though. But the larger viewfinder (especially for those of us who need reading glasses) is simply phenomenal. Just eyeballing things, even just using the on-board flash, the exposures look great and the colors seem very natural. Nothing looks "flashy". Good, quick response, nice feel when shooting.
So, uh, Ike . . . when's my housing going to be ready????
Hope everyone had a great day.
