I installed an MB-D10 grip on my D300 and the main command dial, sub-command dial, and the multi selector controls on the grip do not respond. The shutter release and af button on the grip DO respond.
The batteries, one in the camera and one in the grip, are fully charged, the control lock switch on the MB-D10 is in the unlock position, the grip is securely and properly mounted to the camera base, and the contacts are clean. The battery sequence switch is set to the grip battery first, which is the default. I have searched through the menus trying to find some setting that I have overlooked, to no avail.
I have had the camera for a year and it functions flawlessly. The grip appears to be nearly brand new, with no signs of wear or even having been mounted on a camera.
I think I am overlooking a simple setting which would enable all of the grip's functions to respond properly. Any suggestions on what I am missing will be greatly appreciated.
Thanks so much for the reply. I have tried every conceivable combination of resets, disconnects, battery removals, etc. I don't think there is any camera setting that I am missing. I did get the questionable control functions to work intermittently a couple of times, which leads me to believe there is some sort of connectivity problem within the grip regarding those particular functions.
I have a return option from the seller so I think I will exercise it and try another one.
I like the heft of the D300 with the grip for handheld work so maybe the next one will work properly.
Thanks again for your concerned response. I will certainly try your remedies and hope that they cure the problem!
I recently bought an MB-D10 for my D300s. I had a very similar situation to yours, although with the added feature of the camera power cycling every few minutes. After much frustration I found that it was a battery issue. I have a couple of third-party EN-EL3e batteries, as well as Nikon. I found that the output of one of the batteries was 1800mAh, whereas the Nikon batteries are 1500mAh. Once I changed back to a 1500mAh battery both in the camera and the grip, it all worked.
Don't know if this helps you, but with much embarrassment I will put it out there.
Is the MB-D10 a Nikon or a third party manufacturer?
Make sure that all of the electrical contacts on the D300 and MB-D10 are clean. These are gold alloy and do sometimes tarnish just enough to cause an intermittent or constant problem. A little alcohol applied with a lint free cloth should take care of poor contacts.
Thanks Tony, Paul, and Al for the responses and excellent suggestions.
I have returned the malfunctioning grip to the seller-he had a 14 day return policy-and obtained another one from another seller. The second one works perfectly. Both are original Nikon products and I am using Nikon batteries.
I can see how the on/off switch on the grip could eventually fail with frequent use over time, and I will keep the contacts clean to improve performance.
The grip has been invaluable for using the camera in "portrait" mode while shooting indoor basketball recently.
Now if I can improve my techniques to fully utilize the capabilities of my equipment, I will be in good shape!
