Q
Is there a open skeleton frame to use the external microphone?
A
The V50x comes with a skeleton case with a slotted rear door replacement, but there is no opening to allow plugging in an external mic. As a note, the sound recording, even while in the completely waterproof case, is better than I had expected. If you're not worried about moisture, there is a threaded tripod mount on the bottom of the camera and an adapter that will allow you mount the camera without using the case. 
Q
Am I supposed to use an adapter to attach to a Nikon camera? If so, can you suggest an adapter?
A
No the other way this is to be able to mount the Nikon lenses onto the micro 4/3 camera body
