A new version of the Lee Filters SW150 system holder has been introduced that allows compatibility with a broader range of extreme wide angle lenses, and which has been designed to reduce the impact of reflections from the rear surface of fitted filters. The Lee Filter SW150 Mark ll now allows the existing 150mm-wide filters that were developed for the original SW150 to be fitted to four lenses using model-specific adapter rings – with more adapters on the way for additional lenses.

The SW150 system is designed to overcome the issue of fitting filters to lenses that feature built-in extended petal-style lens hoods that do not have screw threads for filter systems to be attached. The original system, which was designed specifically for the Nikkor AF-S 14-24mm f/2.8G ED lens, used a special two-part collar that could lock on to the lens barrel and onto which the filter holder could be attached. The new version operates in much the same way, but now has dedicated collars for these lenses:

  • Samyang 14mm f/2.8 ED AS IF UMC
  • Sigma 12-24mm f/4.5-5.6 ll DG HSM
  • Tokina AT-X 16-28mm f/2.8 PRO FX
  • Nikon Nikkor AF-S 14-24mm f/2.8G ED

Lee says new collars are on the way which will expand the number of lenses the system can be used with.
The new design of the SW150 Mark ll makes it possible to use the company’s Big and Little Stopper neutral density filters, as well as a polarizer and neutral density graduated filters. The graduated filters for the SW150 Mark ll measure 150x170mm, while the Big and Little Stoppers and the polarizer are 150mm square. The filters are out-sized to ensure they cover the viewing angles of extremely wide lenses, and the holder has slots to accommodate up to two filters at a time.

An important addition to the system is a new Lightshield that fits between the filter holder and the rear of the closest filter to the lens. The shield blocks light coming from behind the camera to prevent reflections on the rear of the glass creating flare in the image. These reflections are especially noticeable with the Big or Little Stopper filters fitted to the holder as the light from rear reflections will be far brighter than that passing through the filter. Owners of the original SW150 system can buy the Lightshield on its own to fit to their system.

Pricing for the Lee Filters SW150 ll system has yet to be announced. For more information, when it becomes available, visit the Lee Filters website.
