I know that TECHNICALLY happiness cannot be bought... but it comes pretty close in the form of a Canon 5d Mark ii. I have been waiting for this beast for a few years, and finally the day came. I clicked "place order" and a few days later, it's here. And last weekend I shot my FIRST session with it. It handles very much like my 50d, just better. In pretty much every way.
Here's my first preview shot with my new baby... the Mark ii that is... the baby isn't mine. :)
