I've had my camera for about 3 months and I have never had a problem moving the focus point around, but today, while I was hiking, it started spazzing out. Like when I half press the shutter button, the focus point starts jumping around by itself. Note, this only happens when I'm looking through the viewfinder. If I go into Live mode, I works just fine. I have a D7200 and my only lense is the nikkor 50mm 1.8. Anyone know what the problem might be?
EDIT: Sorry, I don't know what section to post this thread.
