Product Information
Full details
The Lee SW150 Neutral Density 0.9 Standard Resin filter is designed for photographers seeking to control exposure and introduce motion blur in their images without altering color balance. Its primary benefit is enabling longer exposure times in bright conditions, allowing for creative effects like silky water or streaking clouds. A key consideration is that it requires a separate SW-150 filter holder. This 150x150mm resin filter evenly reduces light across the visible spectrum, offering a 3-stop exposure reduction.

FAQs
What does 'Neutral Density 0.9' mean?
A Neutral Density (ND) 0.9 filter reduces the amount of light entering the lens by 3 stops. This is achieved by absorbing light evenly across the visible spectrum.
Do I need a special filter holder for this filter?
Yes, this 150x150mm filter requires the specific Lee SW-150 filter holder system, which is sold separately.
Will this filter affect the colors in my photograph?
No, the 'Neutral Density' designation means it is designed to reduce light evenly without altering the color balance of the scene.
Can I use this filter with any lens?
The filter itself is compatible with any lens as long as you are using the Lee SW-150 filter holder system attached to that lens. Note that larger filters may cause vignetting on very wide-angle lenses.
How do I calculate the correct exposure time when using this filter?
A 0.9 ND filter provides a 3-stop reduction. If your meter suggests an exposure of 1/15 sec at f/8 without the filter, you will need to increase your exposure by 3 stops. This could mean increasing the shutter speed to approximately 1/2 sec (15, 5, 1/15 -> 1/2) or opening your aperture by 3 stops (if possible).
How should I clean the filter?
Use a soft lens brush or blower to remove dust. For smudges, use a microfiber cloth with a drop of lens cleaning solution, wiping gently from the center outwards.
Troubleshooting
Filter introduces a color cast
This filter is designed to be color neutral. Ensure no other filters with color biases are being used simultaneously. Check for lens flare or internal reflections, which can sometimes be misinterpreted as a color cast.
Difficulty sliding filter into holder
Ensure the filter is oriented correctly and not forced. Check the filter holder for any debris or obstructions. The filter should slide smoothly.
Image appears overexposed despite using the filter
Verify that the filter provides the correct exposure reduction (3 stops). Adjust your camera's exposure settings (shutter speed or aperture) to compensate for the filter's light reduction. Ensure the correct filter strength was selected.

Setup, Compatibility & Care
Setup: This filter is designed to be used exclusively with the Lee SW-150 filter holder system. Ensure the holder is securely attached to your lens before inserting the filter. Slide the filter into the designated slot within the SW-150 holder. Multiple filters can be stacked if necessary, but be mindful of potential vignetting on wider lenses.
Compatibility: Primarily compatible with the Lee SW-150 filter holder. It is not designed for smaller 100mm or 75mm systems, nor for screw-in filter mounts.
Care: Handle the filter by its edges to avoid fingerprints on the optical surface. Clean with a soft-lens brush or an air blower to remove dust. For stubborn smudges, use a dedicated lens cleaning solution sparingly on a microfiber cloth, wiping gently in a circular motion from the center outwards. Store the filter in a protective case when not in use.
