  • Enables slow shutter speeds for motion blur with 0.9 density
  • Allows wider apertures to separate subjects using graduated design
  • Reduces effective ISO above 400 for bright outdoor use
  • Prevents overexposure in video with fixed shutter speeds
  • Extra width fits SW150 holder for horizon adjustment

0.9 Graduated ND Filter for SW150

The Lee Filters 0.9 Graduated Neutral Density Filter is a 150x170mm glass filter for the SW150 holder system. It reduces exposure by three stops across half the frame to balance bright skies with darker foregrounds. Landscape photographers use it to retain highlight detail in high-contrast outdoor scenes. The medium edge provides a noticeable but smooth transition between the dense and clear areas.

Suits landscape shooters needing precise horizon

This filter suits photographers using the SW150 holder who want finer exposure control than the standard two-stop filter. The extra half-stop and wider 170mm height allow vertical adjustment to match uneven horizon lines. Buyers who need a hard transition line for flat horizons or a softer blend for complex skylines should look at other edge types. Users of smaller filter systems cannot mount this 150mm wide filter.

Three-stop density with medium transition edge

The defining specification is the 0.9 optical density, which equals three stops of light reduction on the graduated portion. Combined with the medium edge profile, it determines how abruptly the filtration changes across the 170mm length. This density and edge combination decides whether the filter matches the specific dynamic range and horizon profile of your scene.

Questions about this item

Does the 150x170mm filter come with the SW150 holder or must I buy it separately?

The filter is designed for the SW150 holder system; the holder itself is not included and must be purchased separately.

Should I choose the .9 density or a different strength for balancing bright skies?

The .9 filter provides three stops of light reduction, suited for strong horizon transitions; select a different density if you need less or more attenuation.

What does the .9 rating actually do to my exposure in the field?

It cuts three stops of light on the graduated half, letting you use wider apertures or longer shutter speeds without overexposing bright areas like sky or snow.
