Bob, I have the 800 as well and it broke my heart when i compared just how good the $3K camera was against the $12K Pentax. However time has shown that the D800 cannot match the color transitions that the Pentax delivers and this is particularly true with fine art copy work.It does deliver better resolution than the D800E but the difference is clearly not worth $9K. Every time I decide to sell the Pentax i run into something it can do that the Nikon can't so I still have it. Oh and i do get a lot more exercise carrying it around and-that is a benefit isn't it :).
My point with the Fuji sensor that never happened is that it allows for a very different way of shooting photographs not to mention perfect color almost all the time. You can indeed get that good color with the Nikon but you have to work a lot harder to get it and as you know, if you have to get that look in 1,500 photos it's a pain in the mmmm eyeballs???? You know, that gas that comes out of the monitor and puts you to sleep.....
You are right, no matter how good a point and shoot looking camera is, it can't be the main camera but as I have posted, I drag out my Canon G10 late in a reception when my back is hurting.
As i think about winding down on the number of weddings i shoot i am seriously looking at what I should get for travel. The afore mentioned cameras are just too heavy. My current candidates are the new FF Sony $2.2K point and shoot or the Canon APSC point and shoot, I forget the numbers right now but a friend of mine has the Canon and it is pretty impressive. Have you looked into the area?
Anyway, good to hear you are still a geek like me and understood my post.
