The Lindahl Professional Vignetter is used as a lens shade (which extends from 4" to 10"), and as a vignetting system. It features three standards for vignettes or filters. A double 3" filter slot is next to the lens. The center standard is for 4.5" glass "neutral-density" vignettes. Any vignetting device that may cause flare should be used here. The front standard is for 4.5" Hi-Key vignetting and montaging masks. The front of the vignetter has metal plates which allow the use of magnetic vignettes. Recommended for longer focal lengths i.e. 150-180mm. Adjusting the standards forward and backward gives you complete control of all vignetting effects.
NOTE: This item mounts directly to Hasselblad CF (Bay 60) lenses. An optional adapter ring is required to fit CB, CFi and CFE lenses (LIARHCB). Other lenses require an optional size 8 adapter ring.
