Hoya ND4 HMC 49mm filtro a densità neutra con custodia

The Hoya ND4 HMC 49mm Neutral Density Filter is a high-quality optical accessory designed for photographers who need to reduce light entering the lens by 2 stops. This filter allows for creative control over exposure, enabling long exposure effects and wider apertures in bright conditions. The Hoya Multi-Coated (HMC) technology minimizes reflections and flare, ensuring sharp, contrast-rich images with neutral color balance.

Advantages

With a filter factor of ND4 (1/4 light transmission) and an optical density of 0.6, this filter provides precise light reduction. The multi-coated glass reduces ghosting and improves light transmission, while the aluminum alloy frame ensures durability and a secure fit. The included protective storage case keeps the filter safe when not in use.

Suitable for

• Long exposure photography (waterfalls, clouds, motion blur)
• Using wide apertures in bright sunlight to achieve shallow depth of field
• Video recording to maintain shutter speed at 180-degree rule
• Landscape and architectural photography where neutral color rendition is critical
