This Formatt-Hitech 100mm Modular Filter Holder system will permit you to use numerous different types of filters depending on the shot you envisioned.
This system is very versatile as it allows for up to three filter slots to be fitted to the front and it takes a variety of filters from the 100mm square filter or the 100x125mm or 100x150mm graduated filter.
By using either the spring or plain spacers included in this system, it won’t limit you to use only three filters per holder but rather allow you 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 or one 4mm and two 2mm-thick filters, depending on your specific needs.
Once you decided on the number of filters you desire for your shot you can secure everything in place with brass nuts that are included in the system.
To further modify the system, there are additional screws and spacers to fit all your requirements that can be purchased separately.
The lightweight Formatt-Hitech 85mm Modular Filter Holder system is constructed from durable, rigid aluminium for increased stability.
You need to buy separate adaptor rings, available between 40.5mm and 105mm to attach the holder to a camera lens.
A separate 105mm threaded ring is available for attaching a polarizer or hood.
Additional spares kits are also available for purchase separately.
