I have a d4 also, never had any issues so far. I use my 400 vr all the time, i shoot high school football, and never had a problem with my lens getting stuck. Also came from d3s, and i think the autofocus is much better more keepers with CH bursts , high iso the same with d3s, better dynamic range, and as far as xqd cards, personally i don t have a problem with. I love my d4.
