The Zeiss ExoLens Pro is a wide-angle lens attachment which can be used with an iPhone. It transforms the standard iPhone camera lens into a wide-angle one which offers around 18mm (full frame equivalent, compared with 28mm for the standard iPhone lens).
It is compatible with all of the current models of iPhone, going back a few generations. If you buy the Edge mount to go with it, you can use it with iPhone 6 / 6 Plus and later.
For this review, we have been using the ExoLens with an iPhone 6S. The Zeiss ExoLens Pro retails for $149.99 / £139.99.
