Some animals don’t require much of a telephoto lens. The chickadees at Elk Island (and almost everywhere else too) are a lot of fun to photograph, and are quite brave. They will come very close, even sit on you (briefly) if you stay perfectly still or if they think you have food. They’re also very acrobatic in the air, so it’s fun to try to catch them in flight.
This was taken with my slow-focusing and not very telephoto 150mm macro.
