Hoya 58 mm HMC NDx4 Screw-in Filter
Size:58mm Neutral Density filters evenly reduce the amount of light passing thru the lens without effecting color. Ideal for reducing bright light in large aperture situations when a narrow depth is field is needed. Allows for slower shutter speeds when blurring or showing of movement is desired. Allows balancing of exposure to highlight a key subject. Lets you use higher speed films in bright light. Hoya Neutral Density filters are available in most sizes and in three strengths: .3 (2x) Reduces the light one f-stop. .6 (4x) Reduces the light two f-stops. .9 (8x) Reduces the light three f-stops.
- Neutral density filter for wider apertures or longer exposures without affecting colour balance
- Enables slow shutter speeds to be used, especially with fast films, to record movement in subjects such as waterfalls, clouds, cars, seas etc
- Decreases depth of field by allowing wider apertures to be used, which helps separate subjects from their background
- Decreases the effective ISO of high speed film (ie: above ISO400) and allows it to be used outdoors in blight situations
- Allows cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which would normally cause over-exposure
- To fit 58 mm thread size
