In December I finally upgraded my camera to Canon 5D Mark III after shooting for almost a year with Fuji X100 since I broke (sunk in the sea) my Canon 1D Mark IV. And all the Canon lenses sitting in my bag unused were definitely bothering me.
A while back I bough Canon Extender 2X for my 70-200mm that I didn't get to use much, so the moment I had my new camera on my hands I walked over the Williamsburg bridge to take some shots of New York and Brooklyn from there.
Canon EF 70-200mm f/2.8 L + Canon Extender EF 2X II = 400mm f/5.6
