This is probably the only place I can find a proper answer. I just got my D7k back from a servicing, adjusting the notorious back-focus issue.
Now here is a question. How long does it take for your D7k to shut off? My firmware is the newest one:
A: 1.02 B: 1.03 L: 1.006
I just have a feeling it is way too slow. At least 1 - 2 seconds. I thought the rating was 0.4 seconds? Sometimes it stays on for around 5 - 10 seconds without responding.
This was the 6th time I sent it in and I'm really fed up with this body. After the 4th repair of the other notorious oil-splatter issue, they gave me a new body. Except the new body had the back-focus issue.
I may have to escalate this issue again. I feel that getting a new body with 6 repairs was rather a poor compensation for all the time and money wasted on trying to repair it.
And I do have the battery grip; I've heard that the grip causes bad things to happen but all answers on other forums were pretty vague.
