Hey, please read your camcorder instruction manual carefully. You should find a corresponding info for the chip cards that can be used. A sticking point is the writing speed of the chip card. What card type can the camcorder handle. Hope to have been of some help to you. 

Dear Customer, Thank you for your question. Please check the following steps to setting the focus: (Do not look at too close objects) Step 1. Cover the right objective lens with your hand or close your right eye, rotate the central independent focusing wheel until the image in the left eyepiece is sharp and clear. Step 2. Now cover the left objective lens or close your left eye, rotate the right eyepiece focusing wheel to adjust the diopter of the right eye until the captured image is sharp. 

No. This is manual adapter. I've used it for a vintage Takumar 70-200mm and it worked well if all you want is to mount it and have manual control. 

Yes these lenses should work fine with a Nikon G adapter to Fuji X mount.
