My first attempt at the ‘quick point and shoot’ with the telephoto lens. I was instructed that my goal was to get the object centered, and not to worry too much about focus, as that will come with practice (and getting used to the extra weight, heft and balance of the camera with the lens on it). That getting what you want in the viewfinder is the tricky part with telephoto.
I still managed to focus and hold still enough to identify what airline the plane belongs to, which I couldn’t do with naked eye. :)
