Review on Camera Fisheye Kaleidoscope Android Smartphones by Robert Petrig

First, I use an iPhone 8 Plus with a case. The clip spring is strong, not easy to slip, and fits a fairly thick phone case. Wide angle and fisheye lenses work great but require some adjustment to properly line up with the camera lens to avoid vignetting (see my fisheye image). The macro lens is very powerful with very shallow depth of field; in other words, it must be held at a precise distance from the object (see photo of the keyboard keys). The CPL polarizing filter is great for landscape photography and really brings out the clouds. The #6 kaleidoscope lens has limited use but can sometimes make interesting photos (see my picture). One small issue is that the lens caps on the large end of the lens come off easily, requiring you to hold the lens in place. no cap (as I found). However, this is a complete set of good camera lenses at an affordable price.
