The LEE100 Tandem Adaptor allows two LEE100 holders to be joined together and rotate independently from each other. This allows for a filter holder combination to hold up to five 100mm-wide and 2mm-thick filters, as well as a polarizer filter that can be purchased separately. Insert the LEE100 Tandem Adapter into the farthest filter slot of the LEE100 Filter Holder. This will enable the attachment of another LEE100 Filter Holder at the front using the LEE100 Tandem Adapter.Joining two holders together allows photographers to independently rotate each holder. This means two ND grad filters can be positioned at two different angles. The maximum number of filters which by joining two holders together, is five (two in the rear holder and three in the front holder).This set up can be used at a focal length of approximately 26mm on a full frame sensor, without any cutoff.
