Long time no posting here...

I have noticed that my Meike grip, attached to the D7000 caused the "memory in use" LED to blink, even if both camera and grip switches were off. I did "padding" with some tape on other side of the grip as per suggestions on the forum, which (i believe) solved the problem. But soon enough i came across of a used genue grip and switched and never looked back. The combination of D7000 + MB-D11 + 70-200 made me to buy a different schoulder strap though...

But back to the topic. i do belive that bad connection between Meike grip and D7000 can be cause of both batteries to be dead after some time.

Best regards,
