500mm · f/8
The Nikon Reflex Nikkor-C 500mm f/8 is a compact, lightweight catadioptric lens offering acceptable sharpness and zero chromatic aberration, but with lower contrast, a central hot spot, and slow effective aperture (closer to f/11). Its fixed f/8 aperture and donut-shaped bokeh are notable drawbacks. Build quality is excellent, with smooth manual focus and a sturdy tripod collar. It suits photographers seeking an inexpensive, portable 500mm lens for bright-light use, but its optical compromises make it poor for general photography.
