The Hitech 100mm Aluminum Modular Filter Holder is a system that will permit you to use numerous filters depending on your needs in order to create the shot you envision. It comes fully assembled but can be modified to accommodate the filters you require at any moment. It removes the traditional limitation of only three filters per holder by the use of the included plain and spring spacers. Using these included spacers, you can alter the configuration to accept resin or glass filters as thick as 4mm. The spacers can be arranged to accommodate up to three 2mm-thick filters, one 4mm-thick filter, or one 4mm and two 2mm-thick filters.
This holder is constructed from durable, rigid aluminum alloy for increased stability while still remaining lightweight. Additionally, this holder uses the same optional 105mm front accessory rings as the nylon MK4 holder, allowing for greater versatility between both systems.
The included filter spacers permit you to use filters ranging from 4 x 4", 4 x 5.65", and 4 x 6" for the greatest amount of flexibility. You are also able to easily modify the number of filter slots with your holder; once you decide upon the number of desired slots, included brass nuts can be used to secure everything in place. Additional spacers and screws are also available to further expand the system.
