So I decided to get a new longer lens. I was going to order a used Sigma 150 to 500mm lens but then I saw that a new 150 to 600mm lens wasn't much more. They both had optical stabilization which would be helpful. Also, my current 500mm lens was starting to have some issues. I figured it was time for a new one. The lens arrived today, so I figured I would go try it out. I saw that the Air France 787 was cancelled but I figured I could catch the Fed Ex MD-11 coming in.
