SW150 Mark II Filter System




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 and Big Stopper 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.


The SW150 Mark II system can be used with the following lenses:


  • Nikon AF-S Nikkor 14-24mm f/2.8G ED
  • Nikon 14mm f2.8 D AF ED
  • Canon EF 14mm f2.8 L II USM
  • Canon EF 11-24mm f4L USM

Canon EF 11-24mm: Please note that due to the physical size of this lens, and the extremely wide angle of view, the SW150 filter holder will vignette at the widest angles. To avoid this we recommend using a minimum focal length of 13.5mm when using the filter holder with two filter slots and 12.5mm when using the holder with one filter slot.

  • Samyang 14mm f/2.8 ED AS IF UMC
  • Sigma 12-24mm f4.5-5.6 DG HSM II
  • Tokina AT-X 16-28mm f/2.8 PRO FX
