The KIWIFOTOS LA-72S6850T Lens Adapter is a two piece adapter(back component & front component) made of black anodized aluminum. The lens adapter provides two 72mm filter mount for adding effects filters or other lens accessories to the FUJIFILM FinePix S6600 / S6700 / S6800 /S6850/ S4600 / S4700 / S4800 Camera. With the back component of the adapter users can add a 72mm filter to improve picture quality at the widest zoom and it will not cause vignetting. In this case lens full zoom function is not applicable. For use with teleconverter and macro/close up lenses in full zoom screw both parts together and add a 72mm filter, it may cause vignetting, however. The lens adapter will protect your camera lens when the lens is extended. The special design of a smooth inner ring of the lens adapter helps protect your expensive camera from scratching during installation. **Exclusively at KIWIFOTOS**‍
