iPhone Wide Lens by Sandmarc

Sandmarc sent me a wide lens for my iPhone. What can I say, my first impressions are very positive. The quality of the materials is really high, as opposed to what I expected. I tested the lens and I must say that the view angle is really wider (x 0,56). As a GoPro user I can say that the viewing angle is quite similar to that of a GoPro set to Linear.
In the package you can find the lens, a cover for your specific iPhone with the graft to screw the lens, and a kind of pliers to use the lens without having to use the appropriate cover.
