I sometimes think that it's impossible to capture a bee which is flying. It is not without reason as I have limited lens. But I suppose it is no time to moaning about, but to practice continuously. I only have a standard lens 15-55mm lens kit and that's it. All I do is move to the object closer than you probably do when you have zoom lens. This bee is probably annoyed because I have been nosy to see what they're doing and then fly away. That's when I spontaneously release the button. Got it!!
