do you find that you grab it over the d600 or the D3s or the D4 for weddings?
I use all my bodies. For faster AF and low light, I use the D4s' and D3s. The D800 is capable but, it can struggle a bit in low light. The D600 for me now is great for a walk around light weight camera when I don't need 36 MPs. If you're deciding on a camera with resolution and price the D600 would be my choice.
