Doubleside tape.. I used the monster strong black 3M industrial tape for this. mostly becuase I wanted to have a monster grib on the little magnetic ring thingie.
Magnetic smartphone wideangle lens 0.5X (avoid the 180deg Fisheye which is far too big)
This is type the lens I used Here is another small compact lens
Cut a hole in the doubleside tape with a hole-punch of sorts. I got stuck in the punch, so it may be worth using a piece of backing on both sides of the tape for the punch part.
Trim the tape so it fit on front of the X4 and wrap a little around. push the tape INTO the front hole to get a snug fit ON the front of the camera (not the lens) that will block the blue light from inside the X4 to avoid blue "glare" reflections in the back of the lens. don't ask how I figured that out.
Then peel the backing from the magnetic mounting ring and attach it a little high on the exposed black tape. bam. that stuff is not going anywhere. you can now attach the magnetic lens. keep it a little high to avoid vignetting in the top corners.. this is becuase the camera inside is angled up more than the elegant front of the X4 is.
Notice I wrapped the tape back around the body a little to make sure I have a good grip on the X4. its a little sticky, but thats fixed easyly by rubbing fingers on it a little after installing. ;-)
