Filter kit uses a new system that allows you to remove and remove filters in seconds. PL filters require you to select and replace the best filter to reduce reflections, slow shutter speeds with ND filters, or to pursue photographic expressions. Sometimes you experience the annoyance of removing and removing the filter is more troublesome than those using filters. Note: The filter does not have a front screw, so C-PL and ND filters cannot be stacked. When installing one touch release filter and a commercially available screw-in filter, please install the screw-in filter between the lens and the lens adapter. Vignetting may occur depending on the lens used on the system using the adapter. Due to the different design of the lens, it is only a guide, but if a full size, vignetting may occur from around 22mm with a wide-angle zoom lens, and 35mm with a standard zoom lens. For APS-C, vignetting may occur from around 0.4 inch (11 mm) around 0.8 inch (20 mm) in wide-angle zoom lenses.
