[렌즈의 언어] 반사 렌즈 — 도넛이 된 불빛

Shot on a 500mm reflex mirror lens: a city street at night with every out-of-focus light in the background turned into a ring-shaped donut bokeh with a dark hollow center, dozens of glowing rings in magenta, amber and cyan overlapping, a single sharp subject in the plane of focus — a red traffic light — in the middle of the frame. Slightly low contrast typical of mirror optics, very shallow depth of field. No text, no letters, no logos.
