Evening all, Among other things I've been pondering purchasing a full frame dslr. Based largely on price I have decided to start with the Nikon D3 series. KEH has three different versions available and since it is the lowest cost I may get the D3. What is the practical difference between the D3, D3X and D3S. I realize the MP counts are different and the D3 has no video capability and have no problem with that. Some difference in shutter speeds, buffer size apparently, ISO capabilities and other things but what am I going to notice or miss or just wish I had? I don't need ISO higher that maybe 3200 and very rarely higher than 1600. I won't be covering sports with it or news, maybe an occasional wedding though what I already have is fine for that.AF ability is no big deal as most of my glass is manual focus. Mostly I just want to get a full frame digital body without spending a frigging fortune for now at least. I find that the top of the line series has always been my preference all the way back to the F2 and I expect the D3 will suit me better than the D300. Are there any real practical differences, things that will make me wish I had spent more for the higher level? I know it's ancient by todays standards but I can live with that. Rick H.
