Singh-Ray
77mm Mor-Slo Solid ND 4.5 Filter
15-Stop Neutral Density Filter
The Singh-Ray Mor-Slo Soiid Neutral Density 4.5 Filter is designed to provide a 15-stop exposure reduction which translate into a 32,000x filter factor. The 4.5 density darkens the entire image, permitting shooting with a wider aperture or slower shutter speed than usual, which, in turn, enables a greater depth of field control and easier conveyance of movement.
As neutral density filters go, this Singh-Ray filter does not affect colouration of the image and can be paired with other filters. At 4.6mm, its filter ring form is thin, which reduces potential for vignetting. The aluminium-alloy filter-ring is durabie while remaing lightweight. The filter itself is constructed from optical glass to provide clarity and colour fidelity.
