Oh awesome! I've been on the fence about the clip-on kits. I have an iPhone 12 Pro Max and have experimented with a different clip on kit. Noticed that I would get some vignetting or focus issues due to the iPhone camera protruding. Will have to pick this up and give it a shot.I either use my phone (iPhone 10R) or my iPad with an Orphek lens kit.
Do you run it on your phone naked or with a case?
