I was out in the backyard and spotted the hummingbird at my neighbors feeder, managed to track it to the bushes where it rested for a short moment. @300mm and handheld, and cropped down much. So the quality isn't particulary striking but thought the moment was special. And, I will return this lens to my friend. He referred it as "crappy" I say I'll get a prime tele one of these days.
