HOYA PRO ND-EX Neutral Density Filter ND64 ø49mm - YYN3649

Neutral Density filters allow precise control of light reaching the sensor, both for photography and video. Reducing the amount of light makes it possible to lower the shutter speed and practice long exposure, while in video, this reduction of light will allow the use of wide apertures such as F1.4 for bokeh even in bright light conditions to maintain the 1/50 sec shutter speed depending on your needs. HOYA uses an exclusive coloring process named ACCU-ND for uniform color deposition, resulting in accurate density values and perfect color neutrality. HOYA PRO ND-EX filters reduce transmittance equally in the visible and infrared spectrum. HOYA PRO ND-EX8 reduces light by 3 f-stops (T%= 12.5%), PRO ND-EX64 by 6 f-stops (T%= 1.56%), and PRO ND-EX1000 by 10 f-stops (T%= 0.10%), making it the most popular filter for long exposure. HOYA ultra-clear optical glass is precisely inserted into an aluminum ring with back and front threads for lens cap installation. It's possible to stack filters and therefore achieve different densities; for example, a combination of a PRO ND-EX8 and PRO ND-EX64 will reach a 9 f-stop density equivalent to PRO ND-EX500 (T%= 0.20%). It's highly recommended to conduct a vignetting test before shooting. HOYA PRO ND-EX filters are available from diameter ø49mm to ø82mm.
