Marumi DHG Coated Achromat (for edge-to-edge sharpness and clarity) Macro -330 (+3) 77mm Screw-on Close-up Glass Filter

Marumi DHG Achromat Macro -330 (+3) 77mm Lens is a high-grade, screw-on close-up filter designed to convert standard camera lenses into macro lenses or enhance existing macro capabilities. Unlike single-element close-up filters that cause distortion and color fringing, this achromatic magnifier uses a dual-lens construction to maintain edge-to-edge sharpness and clarity.

Key Specifications & Capabilities

Magnification Power: +3 Diopter strength (often designated as the 330 model because it yields a focal length conversion of roughly 330mm).
Filter Thread Size: 77mm, making it highly versatile for professional lenses or easily adaptable to smaller lenses via step-up rings.
Achromatic Construction: Features two laminated glass elements made of specialized crown glass with low dispersion to eliminate chromatic aberration.
Digital High Grade (DHG) Coating: Equipped with an ultra-low reflection coating and a matte black outer rim to eliminate ghosting, flare, and internal sensor reflections.
