The Freewell magnetic filter system starts with a slim magnetic filter holder that threads into your lens- in this case, any lens with an 82mm diameter (or 77mm with the included stepping ring). Filters and lens caps then snap right on, held snug by built-in magnets. This kit includes one filter adapter for 82mm lenses, one 77-82mm stepping ring, one UV filter, one circular polarizer, one ND8 (3 stop) ND, one GND1.2 (4 stop) graduated ND filter, and a pair of magnetic caps- plus a handy case to carry it all around.

Please note: The UV filter is an "alternate" filter holder: it can be threaded to the lens and serve as a base for other filters and caps.
