The 150 x 150mm SW150 Little Stopper Neutral Density 1.8 Filter from LEE Filters is an ND filter with a 64x filter factor that provides a 6 stop exposure reduction. Its 1.8 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.

Asked by: Amit K.
Amit, to use the filter you have asked about you need to also have the filter holder, and the lens adaptor that are shown. The lens adaptor allows the filter holder to attach to the lens. The lens adaptor you choose must be based on the diameter of lens that you are going to use it on. So if you are going to use it on a 77mm diameter lens then you need to buy the 77mm adaptor similar to the one shown. If you have the correct lens adaptor and the SW150 Mark II adaptor as shown then the filter will be compatible with your lens. Typically the 150mm filter is for use on large diameter wide angle lenses. If yours is not this type of lens then you may want to use the 100mm or 75mm filters and required lens holder and adaptor. Alternatively you can purchase round ND filters that screw directly onto your lens without the need for a filter holder and adaptor, but make sure you order the correct diameter filter. Hope this helps.
