I exchange to GoPro Hero 2 with a Hero 3 and let my oldest son inherit the "old" model.
I keep on buying lenses, and I'm as always on the lookout for used bargains. Early in the year I manage to buy a Nikon 45mm f/2.8 pancake and a Sigma 8-16mm wideangle zoom. Both used and both great lenses. And during the last months I get my hands on a used Nikon 50mm f/1.8 pancake as well as a brand spanking new Sigma 18-35mm f/1.8. Both these are also great lenses.
