Upgrade D3 to D4 or D4s?
I currently have a D3 and a D7100 that I use for shooting birds and wildlife. My lenses include the new 80-400 and a 500VR.
I am not really happy with the D7100 and am getting far better results with the D3.It really is hard work to get sharp shots handheld shooting BIF with the D7100 whereas I had no issues with the D300s and D3.
However the D3 also suffers from a small buffer when shooting NEF. I am now considering getting a used D4 to replace them both. Some questions:
Is a used D4 a worthwhile upgrade to my D3? I am looking for a bigger buffer, a few more pixels and better ISO performance. I understand that some are saying that the move from a D3s to a D4 is a backwards step when it comes to ISO.
Should I rather wait and save a bit more and go for the D4s?
A local guy is asking $4500 for a D4 with 50,000 actuations whereas the price of a new D4s is around $8500 here in SA.
