i was i the market to purchase a d800, so i tried a friends d700. the d700 felt like a tinker toy in my hand and the specs say the d800 is smaller than the d700. the auto industry for the last 30 years or so have gone from designing cars for men to designing cars for women. it seems as if nikon and the rest of the camera makers have changed their designs to make cameras for small handed people who can't lift a feather. i can hike all day with a f5 and lense and hasselblad, roll film backs, digital back and lenses. i have large hands and the dinky d700 felt weighless in my hands and i couldn't hold it steady. i never have that problem with the f5. what nikon should have done was offer the d4 body with the 3 sensor options, d4,d800,d800e. similar to a car body with different engine options. yes i tried the d700 with the add on battery pack but it does not have the same feel as the solid body. i am sure there are other men out there who have the same complaint that i have trying to handle these tiny toys in their large hands.
