hi,this Pro Kit filter can not used on 95mm size lens,because we do not have 95mm adapter ring. 

It has a standard screw mount where a tilt mount can be attached. 

I use an iPhone 11 with a screen protector and case on the back and it works well with that. 

The camera comes with a waterproof case that covers the lens. 

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.
