Sometimes strange things happen.
I rather quickly concluded that I was not going to easily get a good picture of a flying Trumpeter Swan with a $25 800 mm manual focus, manual stop down lens. So I started to look at the local Craig’s List, eBay and other sources for a used lens that was auto focus and went out to around 300 mm. Here it is, another $25 lens.
Out of the new lens and camera combination came this interesting shot. I put the swans in the camera. Everything else got in the camera by itself. Sometimes strange things happen.
