Been resisting saying anything. But, I have to.
I received mine last Thursday. I hadn't had much chance to use it until this afternoon. All I will say is its great. Focus seems faster than my D4s. Works great on my 600mm.
I have learned over many years, that whenever there is a new lens or body released, people enjoy slating them. Without really being qualified to.
I remember so well, the pixie dust inside the Nikon 70-200mm. The world was ending!!!
As a friend of mine once said to me, Things always move forward. Very rarely do things go backwards. Manufacturers are in business to sell. They are not going to spend millions, in design and development to go backwards. I have owned the D3, D3s, D4 and D4s. All had improvements over each other. Sometimes, not massive. But still improvements. I always sell my old ones to the same person. He has yet to come back to me and say he wants his money back, because it's no better than he had.
So, if anyone who lives near me, would like to try the D5 themselves and form their own opinion, message me. I am happy to go out for a shoot with them.
Please don't take any of the above as me being arsey. I'm not. Honestly. Just wanted to put another perspective on it.
Hopefully, I will be able to get out soon and do some serious shooting, to explore it more in depth.
