Yes, the infrared night vision binoculars come with a mounting bracket for you to mount it on your helmet. Besides that, it also comes with a neck strap and a headband. It provides 3 wearing methods. 

The 77mm filter size will fit your camera. 

Simple, u turn the plastic bracket around, fit the sq plastic in the other way, then get a wall bracket and pipe and mount your unit on the pie and finally on the wall 

no, it does not 

The adapter will mount the lens and you will be able to use it manually. However, my copy of the adapter does not allow the lens to be fully mounted all the way until it clicks into place. It doesn't quite make it, but it's still very solidly mounted. Also, the manual aperture linkage doesn't work properly (on my copy, at least) so exposure is controlled only by shutter speed and/or ISO. You will be able to manually focus and zoom the lens but no VR, of course. It will be a frustrating experience. Instead, get a 14-140 Panasonic zoom if you can afford it!
