LEE Filters SW150 Mark II System Filter Holder

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 holder opens up opportunities for the creative use of filters, without the need to be concerned about vignetting. 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.

The SW150 filter holder comes assembled with two filter slots, enabling you to use neutral density graduated filters in combination with other filters.

The holder 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. Store your Lightshield as flat as possible, preferably in the filter holder. This will keep it in shape during any temperature fluctuations and ensure that it works correctly. Keep the front face clean and clear of sand or grit. If using a long exposure filter, ensure that the Lightshield is seated properly and that the foam on the filter is accurately aligned with the edge of the Lightshield. Give the Lightshield the best chance to work correctly when shooting in bright conditions. Shade the edges manually by casting a shadow on the seal if direct sunlight is striking the holder. It is good practice to do this in all conditions anyway, to limit the chances of flare and rear reflections from your filters.

The SW150 Mark II system is now suitable for use with a multitude of lenses (adaptors purchased separately from the filter holder)

*Additional lenses will soon be added, so please check www.leefilters.com for the latest list of compatible lenses.
