Lightdow F 240mm F5.6 Reflex 240mm
Its 240mm focal length and reflex design produce a signature donut-shaped bokeh for a distinct, dreamy vintage look. The compact 145x71mm build and 1.5m minimum focus distance offer surprising close-up versatility in a fully manual, mirror-lens package. This lens is best for experimental photographers on Nikon F-mount DSLRs who prioritize artistic, soft-focus effects and precise manual control for landscapes or moon shots.
