Landscape photographers have long understood the benefits of ultra-wideangle lenses, but their design constraints made the use of filters virtually impossible. Now, the SW150 Mark II filter system opens up opportunities for the creative use of filters, without the need to be concerned about vignetting.
The SW150 Mark II filter holder is compatible with our new SW150 polariser, Little Stopper, Big Stopper & Super Stoppers as well as SW150 neutral density graduated and standard filters.
Custom Adaptor for Each Lens
The SW150 Mark II fits via a lens adaptor that has been specifically designed for that particular lens (the adaptor is purchased separately from the filter holder).
Each adaptor consists of a front ring, a compression ring and a locking ring. When fitted, these form a collar that remains on the lens at all times.
