The Haida 150mm Filter holder with the Sigma 14-24mm f/2.8 DG HSM Art lens adapter ring allows you to use drop in filters in the 150x150mm or 150x170mm size. The filter holder can be set up to hold three filters. The kit consists of two main components, a front filter holder, and a filter holder adapter ring. Use of the filter holder is easily accomplished by first attaching the filter holder adapter ring to the Sigma 14-24mm f/2.8 DG HSM Art lens until it has achieved a secure fit. Afterwards, the adapter ring can then be attached to the filter holder to lock both components into place.
This Holder is compatible with Lee SW150 Filters, Haida 150mm Filters, and many other 2mm thick 150mm filters.
