If the longest telephoto lens you own never seems to get you in tight enough to your subject, you have three choices. The first is to get up and get physically closer to your subject. If you can’t, for whatever reason, do this, you can either take the picture as is and crop it to your liking post-capture, or you can use a teleconverter.
