One thing I learnt is, it's never enough. You think you get a D3S it will be enough to last for five years? Then if D4 come out in three years time how? Or maybe a D400 that can shoot the same kind of picture as your D3S, weighs half as much, costs half as much.
Yes, I am contented with what I have now. I may not be contented tomorrow but if I am not contented today, then I should start looking at new equipments, before tomorrow.
Life is too short to want something and not get it
