Formatt Graduated 4 x 4 Neutral Density 1.2 Soft Edge Filter

Neutral Density (ND) filters reduce light of all wavelengths with no effect on the color rendition. The soft edge is generally used with medium to wide angle lenses and when a smooth transition from ND to clear is required. Formatt, a company with three generations of professional filter-making experience, produces this 4 x 4" glass filter for your camera's lenses.

Features:

• Manufactured from Schott White Water Clear Optical Glass
• Consistent color and density to Kodak Wratten standards
• Precision grinding and polishing for optical flatness allowing use on even ultra-long focal length lenses
• Filter edges protected by a frame
