This is a third-party adapter for Fujifilm digital cameras. By tightening the two set screws, it can be fixed to the camera body's lens section, allowing you to attach a 72mm lens filter. This is a used item. Please judge the condition from the photos. The following is a quote from a foreign website: The KIWIFOTOS LA-72SL1000T lens adapter is a 2-piece adapter (rear component and front component) made of black anodized aluminum. This lens adapter provides a 72mm filter mount for adding effect filters and other lens accessories to FUJIFILM FINEPIX S9400W/S9200/S8200/S8300/S8400/S8400w/S8500/SL1000 digital cameras. Using the rear component of the adapter, users can add a 72mm filter to improve image quality at maximum zoom without vignetting. In this case, the full zoom function of the lens will not be applied. To use teleconverters and macro/close-up lenses at full zoom, screw in both parts and add a 72mm filter, but vignetting may occur. Slowly rotate the adapter to allow the user to manually zoom the lens.
