The Xenvo iPhone Camera Lens also works on Android phones but apparently doesn’t fit iPhone 7 Plus very well, so take note of that if you have one. The Lens kit comes with 2 lenses which can be combined into one with both effects: The Wide Angle Lens and the Macro (Zoom In) Lens. The kit also comes with a small case, strap for your neck, clip and soft light like the QIAYA above (but smaller).
I used one in Japan, and honestly it was alright. I mostly only use my phone camera for selfies and pictures of things too close that my DSLR camera would crop out, like taking a photo of a building from across the street. So I had limited use for the clip lenses. But for those without a DSLR camera which can cost $500 USD, it’s a great alternative for customizing your pictures and being creative.
One use I see is taking the kit with me on my hikes since a DSLR camera is so heavy and I often carry it in a whole other bag with extra full size Canon lenses. A small clip on wide angle lens for my phone would be great for those quick landscape nature shots on a casual hike.
There are lots of phone lens kits on the market, but quality can vary a lot. The Xenvo is popular because it is made of high quality metal and rubber. It’ll last. Another good one is Camkix which has the added feature of a bluetooth shutter remote.
