Saw these while walking through the zoo in Seattle and had to get a shot with the wide-angle lens! I'm still shooting with the stock lenses that came with the camera.
The deal I made with myself is that the camera has to earn it's own upgrades. So, once I make enough money with the camera, I'll upgrade it! First though, it has to pay for itself and now I need to do a quick numbers run I think about how much I've made thus far through using it.
