Lens 67mm Filter Mount - Attach Filters to Your Moment Lens (T-Series, 67mm)

Awesome product, super easy to use. Adding filters to my iPhone was a game changer

man I went all in on moment and sorta regret it, hoping it would all come together and work for me. But I've had nothing but issues with their stuff thus far. The problem with this is, if I use a thicker variable ND filter, which was the entire point of buying this fricking attachment, you get vignetting. EDIT: I found out the adapter come with another adapter affixed for wide angle, which was aggravating the vignette issue, once I removed that piece, most of my vignette issue vanished except for a few filter stacks
