D4 upgrade from D3?
I have been an owner of the d3s for about 1 3/4 years. I have read the specs. and I consider the upgrade from the d3s to the d4 minor. Yes, I would gain about 4mp better resolution, and probably improved af, although the d3s is really good. The bodies are similiar. Maybe if the d4 went to 18+ mp I might be more prone to look at the d4. I don't think I will upgrade and the d800 is not really what I am looking for. I would love to have a dx professional bodied camera in the 16+ mp range with good high iso performance for telephoto work in shooting birds.
