Rings

One of the interesting things about manual focus lenses is that they tend to have more pronounced characters than modern lenses. One particular lens, which is very unique in its rendering of out of focus highlights, is the Zoomar Kilfitt 90mm f2.8 Makro lens; it produces highlights with rings within a ring, when shot wide open. Stopped down to f4, the rings are gone! This unusual trait can be used to form part of, or as the sole composition.
