Every lens has a minimum focusing distance: the closest point where the lens can get a sharp focus. Generally, the longer the focal length of the lens, the greater the minimum focusing distance.
Most of the time, this distance isn’t too important: with longer lenses you’ll generally be photographing a distant subject, because you just can’t get close to it.
But, sometimes you can get close to your subject and you’ll want to use a long lens to get that great bokeh (a result of the narrower angle of view). Good examples of this include wildflowers and butterflies. In these cases, to fill the frame with your subject, you’ll usually need to focus closer than that minimum focusing distance.
