I recently purchased an mb-d11 purely for the added weight for my d7000..it really doesn't do much else :) anywho, I noticed while I was out shooting, the d7000's viewfinder would randomly go dark. I'd have to shut off the power and restart to get it going again. Simple fix, but annoying.
The battery was in the grip chamber. The d7000 chamber was empty. A genuine enel15 was used.
Any idea what it is? I never had this problem before adding the grip. Perhaps I'll try the battery in the camera chamber and see if theres a problem there. Just wanted to avoid taking off the grip every time to change the battery.
