The LEE SW150 Mark II Filter System

This innovative system means it's now possible to use filters with a more extensive range of ultra-wideangle lenses than ever before.

Get Creative with Ultra-Wideangle Lenses

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, Big Stopper & Super Stoppers as well as SW150 neutral density graduated and standard filters.

Lens compatibility:

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.

Pentax FA 15-30mm f2.8 ED SDM WR

This lens doesn't have its own Adaptor, however the Tamron 15-30mmm Adaptor fits perfectly.

Samyang 14mm f/2.8 ED AS IF UMC

Sigma 12-24mm f4.5-5.6 DG HSM II

Sigma 20mm f1.4 HSM Art

Tamron 15-30mm f2.8 SP Di VC USD

Tokina AT-X 16-28mm f/2.8 PRO FX

Additional lenses will be added soon - please check back again.

SW150 Screw-In Lens Adaptors

SW150 82mm Screw-In Lens Adaptor

A new range of SW150 screw-in lens adaptors are now available. These adaptors work with both the original and Mark II Filter Systems, enabling either to be fitted to lenses with a screw-in filter thread.

This means that the system is no longer limited to just ultra-wideangle lenses.

The new screw-in lens adaptors are available in the following filter thread sizes:

72mm • 77mm • 82mm • 86mm • 95mm • 105mm

Landscape photographer Joe Cornish gives a practical guide to the SW150 System.

He walks through all the elements of the system, demonstrating how to fit the lens adaptor as well as best practices to get the most from the SW150 System and filters.
