SW150 Mark II Filter System by LeeLandscape 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 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.
Due to the size of the front element of ultra-wideangle lenses, the filters for the SW150 system are larger than those in the standard 100mm range: graduated filters are 150 x 170mm, whilst standard filters, the Little and Big Stopper and the Polariser are 150 x 150mm.
The SW150 filter holder comes assembled with two filter slots, enabling you to use neutral density graduated filters in combination with other filters.
The SW150 Mark II filter holder 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.
