The Marumi DHG Achromat 200 is a high quality doublet-construction +5 dioptre close-up lens. The lens enables the camera to focus close to the subject to enlarge the image on the sensor by about 5x. The two elements give a highly corrected image, with edge-to-edge sharpness. Ultra-low reflection coating and lens edge blacking significantly reduce flare and ghosting. Made in Japan.
