Me and my daughter has long been googling on where to get a crystal ball, and when I finally stumbled on a commercial where the ball didn't cost "a million" I decided to give it a go;

So, some of my first shots using a 60mm wide ball;

The interesting part is that the camera has no bigger problems focusing on the picture "inside" of the ball

On my todo-list - get a mini-tripod to put the ball on

Canon 80D + EF 100mm f/2.8L
