Landscape photographers have long understood the benefits of ultra-wide angle lenses, but their design constraints made the use of filters virtually impossible. Now, the SW150 Mark II filter holder opens up opportunities for the creative use of filters, without the need to be concerned about vignetting. The design of the SW150 Mark II has been adapted from its predecessor and is now not only compatible with LEE’s range of neutral density graduated and standard filters, but also the polariser and Little and Big Stoppers. The SW150 Mark II fits to the lens via a lens adaptor that needs to be purchased separately from the filter holder. Each adaptor consists of a front ring, a compression ring and a locking ring that have been specifically designed for each particular lens. When fitted, they form a collar that remains on the lens at all times.
The SW150 Mk II filter holder comes assembled with two filter slots, enabling you to use neutral density graduated filters in combination with other filters. It also comes fitted with a Lightshield. The shield helps to prevent unwanted back reflections and creates a light tight seal enabling the use of both the Little and Big Stopper. Photographers who already own the SW150 Mark I can purchase the Lightshield separately and retro fit it to their existing SW150 filter holder.
