Hoya PROND EX 8 Neutral Density Filter 62mm

Neutral Density Filter Overview

Neutral density (ND) filters are essential photographic tools that allow precise control over the amount of light entering the lens, enabling greater creative control of exposure. For video creators, ND filters help maintain appropriate shutter speeds to match frame rates while preserving depth of field.

ND Filter Categories

• Light density filters (ND2 – ND8): Reduce shutter speed in bright conditions, allowing wider apertures for softer bokeh and reduced depth of field.
• Middle density filters (ND16 – ND200): Add motion blur in conditions where shutter speed alone cannot achieve it.
• Deep density filters (ND500 – ND1000 / ND100000): Enable extremely slow shutter speeds for creative, surreal imagery beyond human vision.

Light Density Filters Application

Light density filters like ND8 are ideal for shooting with fast lenses (e.g., f/1.4 or f/1.2) wide open in bright light, producing softer and more beautiful bokeh effects.

Hoya PROND EX Series Features

Hoya's PROND EX series offers a wide range of ND filters designed for photographers and filmmakers. These filters use clear optical glass mounted in a lightweight, precision-crafted aluminum frame with front filter threads for attaching additional filters or lens caps.

ACCU-ND Technology

Hoya's exclusive ACCU-ND technology ensures equal reduction of visible and infrared light, preventing color shifts common in lower-quality ND filters caused by poor materials, manufacturing, or infrared leakage. This technology guarantees consistent color fidelity across various shooting conditions.

Use in Video Production

ND filters are indispensable in video shooting. For example, when using Sony cameras in S-Log mode with a minimum ISO of 800, PROND EX filters such as ND8, ND64, ND1000, or their combinations help achieve cinematic shutter speeds and natural motion blur during daylight.

Filter Combinations

Combining PROND EX filters allows photographers to achieve higher ND values for creative effects:

• PROND EX 8 + PROND EX 64 = ND500 effect for surreal, fantasy-like images.
• PROND EX 8 + PROND EX 1000 = ND8000 effect, enabling capture of the Sun's surface with solid color and visible sunspots without overexposure.
