How long have you had your D750? Did it always happen, or did it start after a period of time? Do you remember the approximate number of shutter actuations when it began? Do you shoot a lot of high speed continuous shots? Thanks for any info. Need to keep watch of my own as I don't have a lot of actuations on it.
I bought the cam in July of this year.
It just started a week or so ago.
It has 7456 clicks on it now, so it started a few hundred shots ago.
Yes, lately I'm shooting a lot of BIF with it. (I don't spray and pray, but do short bursts of 3-4 shots.)
Update.
After updating to the latest firmware and having it sit over night, it did not get stuck on the first shot like before.
This is a good sign. If it does do it again however, it is going back to Nikon.
