Apple smartphones have considerable popularity and distribution in all corners of the world. It is not surprising that many manufacturers seek to supplement and improve certain parameters of the iPhone (for example, optics) due to the invention of their own accessories-companions for the smartphone. The Austrian manufacturer of optical devices Swarovski Optik decided not to stand aside. The company has developed an adapter that allows you to mount iPhone to binoculars or telescope. PA-i6 is a set of adapter rings and lenses, as well as an aluminum frame for attaching a smartphone. Thanks to the adapter, the user can take pictures and record on video everything that he sees through the viewfinder. PA-i6 is compatible with Swarovski binoculars and telescopes, as well as several generations of iPhone smartphones.
