Has anyone taken the opportunity to try using this lens mount for the XL1/2? I'm wondering about the 7x on the focal distance. From what I've read, if I try to mount my 9.8mm Kinoptix lense to the XL they are saying it will convert it to almost a 70mm lens? It doesn't sound right to me, but ya never know when trying to rig something together. Any feedback is appreciated.
