I had a Small Rig cage for iphone 13 with mount for Moment lenses and then I've swapped my iphone 13 to iphone 15 and I still want to use my old V2 Moment lenses with iphone 15.
Unfortunately, SmallRig discontinued producing cages for non-Pro iphone models, so I decided to rebuild mount plate, because physical size of iphone 13,14 and 15 are the same and cage itself fits perfectly.
Now I can use my Moment lenses again. :)
