Hi Guys just got a new 2nd D4S body. 

 

I have a Sigma lens older 150-500mm lens. I use this lens for shooting soccer. I use it with Nikon D7100 and D750. 

 

The autofocus works fine with these models. 

 

I got a new body Nikon D4S and Autofocus will not work at all. 

 

I put my lens on my friends Nikon D4S and it will not work for his camera.

 

I then put my lens on a Nikon D6S of another friend and it works on D6S?

 

Is this a software/firmware issue in the D4S? 

 

The lens is older so I do not think it can be docked to the Sigma docking usb. 

 

Any help would be appreciated

First actualize Nikon D4s firmware.
