Fujinon WS 250mm f/6.7

Fujinon WS 250mm f/6.7 is a W-series variant with revised image-circle or coating specifications — Fujinon LF lineage includes several "S"-suffix variants whose precise specifications differ from the base W lenses by region or production year. The 250 WS is essentially equivalent to the 250 W in role and performance.
