D7100 : clonk and display moving
With my D7100 (and 18 200 VR), When I turn it on or push halfway the shutter button, from time to time I get a kind of clonk noise (btw 1 & 4 times) and the display of the viewfinder moves as well. Sounds weird, any idea and on to turn it off ?
I must have done something to turn on this option. I look through the User manual but can't find it.
Any help ?
Have a good day
