LEE Filters SW150 Little Stopper

A glass filter that reduces exposure by 6 stops. This is 150mm by 150mm for use with the LEE Filters SW150 system, designed specially for ultra-wide-angle lenses.

Made by UK company LEE Filters; their reputation has been built on the fact that every filter that leaves the factory has been individually handmade and inspected by one of their technicians, who ensure it meets their exacting standards. "Anything that will compromise image quality, is simply not an option."

  • The Little Stopper is a neutral density filter that reduces the amount of light entering your lens by six stops.


    At six stops, the Little Stopper is ideal for those low-light conditions at the beginning and end of the day (when the Big Stopper's ten stops may prove too much), allowing you to enjoy increased flexibility with exposure lengths. In many shooting conditions, this means that detail and texture in areas of movement such as the sky and water would be retained, while still conveying a sense of time passing.

  • How to use the Little Stopper:

    - First compose your image before fitting the Big or Little Stopper.

    - Take a meter reading without the filter in place, and set your desired aperture and shutter speed.

    - Use the exposure tables to find the correct exposure. Your filter will have come with a printed exposure table.

    - With the Big or Little Stopper inserted into the slot nearest the lens, attach the filter holder as usual and make your exposure.

    - Always use the sturdiest tripod you can when making long exposures, and take care not to knock the camera or tripod. Cover your viewfinder before releasing the shutter to avoid light encroaching onto the sensor or film and causing flare.


    Both the Big Stopper & Little Stopper can be used in conjunction with other filters such as Neutral Density Graduated Filters.


    Other filters should be set up and positioned in the filter holder as normal before using the Big or Little Stopper, remembering to keep the slot in the filter holder nearest the lens free for the Big or Little Stopper.
