The new square Filter-Holder is designed to fit both circular and square filter technologies in particular D-SLRs and VIDEO/ BROADCAST cameras, either semi-professional or professional models (among them the new HD format). It is modular, it can be easily dismantled and set-up to be able to accept filters of 1.6mm thickness (which most photographers use), and 4.0mm thickness (often used in the Broadcast segment in popular dimensions such as 100x100mm (4"x4") and 100x150mm (4"x6"). To prevent the risk of vignetting (dark edges around the picture), this upgraded series filter-holder is fully reversible, which means that a filter can fit in the adapter ring's slot and the adapter ring can be fit in the first filter slot. Therefore the filter can be positioned very close to the lens and the edges of the holder are no longer an obstacle in the field of view.
