The holder is easy to install by removing the standard mounting ring from the front of the lens and screwing the holder on to the thread. The NiSi holder for Fujifilm X100 is built tough made from the same aluminum used in our popular V6 system. It holds two filters from our P1 mobile phone filter range. The holder has no vignetting and allows the use of two filters. The NiSi holder for Fujifilm X100 can be rotated 360 degrees when easily changing between portrait and landscape orientation. The kit features four filters the NiSi Medium GND8 (0.9) 3 Stop Graduated Filter, and a NiSi HD Polarizer. The filters are made from optical quality glass and offer amazing image quality. The NiSi Medium GND Filter is a rectangular filter that helps to darken specific areas of an image, such as bright skies while allowing for a normal, unaffected exposure in the other regions of the image. The medium GND is designed to be moved up and down to control these bright areas. The HD Polarizer help reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. It’s perfect for removing glare on the water, reflections when shooting through glass and provides greater Color and Tonal Saturation.
