This is a monster to work with: bulky, slow, noisy with low light (especially in the blue channel).... but hey.. If you are looking for this body, you knew that already. When you have enough light (studio, outdoors, etc.) this beast really shines. It respons less slow since the last firmware upgrade (v5.4.9).
Quality pictures can be obtained when you have decent glass (Non DX that is). My Nikkor 105mm 2.5 really shines with this body. So choose your glass well.
