Hoya ND400 HMC IN SQ.CASE 58 MM

The Hoya ND400 HMC 58 mm is a neutral density filter that cuts light by 9 stops. It is used for very long exposures and for photographing very bright light sources, such as the sun, safely.

• Filter thread diameter: 58 mm
• Light reduction: 9 f-stops (ND400)
• HMC anti-reflection coatings on both surfaces reduce unwanted reflections and keep light transmission high, helping contrast and colour saturation
• Black filter ring
• Supplied in a square case
• Allows much longer exposure times when you cannot stop down the aperture further or lower the ISO
• On sunny days, lets you use fast lenses at wide apertures, which is useful for portraits and film work
• Helps to match exposure on film cameras where the shutter speed cannot be adjusted
