Key Features 0.6 Neutral Density Filter Increase Exposure Length Slim-Line Mount for Wide Angle Lenses Rugged Black Brass Filter Ring High Quality Schott Glass The B+W 77mm 0.6 ND 102 Slim Filter is a solid neutral density filter providing a 2 stop exposure. This 0.6 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 overall coloration of the image. B+W filters are constructed from high quality Schott glass for increased optical clarity and color fidelity. They feature a brass filter ring for durability as well as jamming prevention. The slim filters are specifically designed for use with wide angle lenses and are only 0.1" / 3mm thick. They do not have front threads for stacking additional filters. Note: This filter ring's outside diameter is slightly larger than the actual thread size, and because of this you may be unable to attach the lens manufacturer's bayonet-mounted lens hood to the lens while using this filter. This is dependent on your specific lens and how thick the front rim of the lens is; with thinner, low-profile lenses usually being affected more. 0.6 ND filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.
