The LEE100 Tandem Adaptor allows two LEE100 holders to be joined together and rotate independently from each other.
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.
