Review on Neewer 37mm Clip-on ND 2-400 Cellphone Camera Lens Filter Kit: Adjustable Neutral Density Filter with Phone Clip for iPhone X 8 Plus 7 Plus 7 6 6S Plus Samsung HTC Motorola iPad and More Smartphones by Mario Schultz

Experience it instantly with FilMiC Pro as soon as the lens ships. Perfect motion blur has been added to 24fps shots instead of those sharp/choppy iPhone shots. Makes the rear view smoother and more cinematic. I didn't notice any significant color shift and saw NO vignetting. Maybe the larger sensor on the newer iPhones doesn't have this problem? My XR has one of the largest and I didn't see any highlights or dark corners. I haven't noticed any color change either, but most of my shots show my son doing things outside. I have not done any "scientific" research on color. The clip is strong because the filter is so light, and it doesn't cover any of the XR's mics, as stated in another YouTube video. My only complaint would be that there is no lens cap included, so I head to eBay to order one from China for a buck. For the price, I'm *very happy* despite my nervousness reading some of those other reviews. I wish I'd bought it when it was $13! However, if you build one yourself using an iOgrapher lens clip and a proprietary ND filter, your cost is over $50. So $33 with next day delivery is a great deal.
