Peter Mackey: Seems to me that Nikon has come up with a nice upgrade model. D3s owners really don't need to change anything unless they want to. For pros D4 perfect when its new body time.For money no object types you will do what you want anyway.I never notice Nikon users wanting to go Canon, but Canon users are always that little bit apologetic that they don't have something better (like a Nikon).
I agree..I just bought a new D3s because it will become unavailable, not interested in the D4 at additional $1,200 of what i paid for the D3s....what percentage of these bloggers will be able to see the difference in picture quality let alone to have a D4 in their hands?D3s is still one of the best DSLRs and will be for a long time.Unless you have unlimited funds you will go broke trying to stay current. I know a deal when I see one...D3s
mrmut: NASA chosen Nikon. The price doesn't mean anything up there, only quality and reliability is important.
sounds like an end user problem...don't borrow my Nikon stuff.
