Marumi DHG 330 77mm Achromat Lens

  • The lens is made from materials of different refractive indexes, constructed in such a way as to minimize chromatic aberration (which in a single lens causes coloured fringes around images because the lens diffracts the different wavelengths in white light to slightly different extents)..
  • Marumi Achromat Macro filters are designed to shorten the focusing distance of your lens and to enhance its macro mode capabilities with outstanding clarity. If your lens already has a macro mode, Achromat will increase and enhance it, allowing for even greater magnification..
  • This Filter are manufactured to the highest standard and feature ultra low reflection coating and are mounted in specially designed rings which feature a low reflection satin like finish..
