By germination of fungal spores and further spore formation, the infestation can spread beyond the initial fungal network. The sensor or glass surfaces of the lens are clouded by the fungal attack and lens coatings may be etched away. The fungus can range from small, barely visible points to an irregularly spreading mesh, to complete \"blindness\" of the optics.\u003csup class=\"reference\" id=\"cite_ref-1\"\u003e\u003c\/sup\u003e\u003c\/p\u003e\n\u003cfigure class=\"mw-default-size\" typeof=\"mw:File\/Thumb\"\u003e\u003ca class=\"mw-file-description\" href=\"https:\/\/en.wikipedia.org\/wiki\/File:Fungus_low_pass_filter_camera_sensor.jpg\"\u003e\u003cimg data-file-height=\"2304\" data-file-width=\"3456\" srcset=\"\/\/upload.wikimedia.org\/wikipedia\/commons\/thumb\/f\/fc\/Fungus_low_pass_filter_camera_sensor.jpg\/330px-Fungus_low_pass_filter_camera_sensor.jpg 1.5x, \/\/upload.wikimedia.org\/wikipedia\/commons\/thumb\/f\/fc\/Fungus_low_pass_filter_camera_sensor.jpg\/440px-Fungus_low_pass_filter_camera_sensor.jpg 2x\" class=\"mw-file-element\" height=\"147\" width=\"220\" decoding=\"async\" src=\"https:\/\/upload.wikimedia.org\/wikipedia\/commons\/thumb\/f\/fc\/Fungus_low_pass_filter_camera_sensor.jpg\/220px-Fungus_low_pass_filter_camera_sensor.jpg\"\u003e\u003c\/a\u003e\n\u003cfigcaption\u003eExample of an image from a camera with fungus in the low pass filter glass.\u003c\/figcaption\u003e\n\u003c\/figure\u003e\n\u003cfigure class=\"mw-default-size\" typeof=\"mw:File\/Thumb\"\u003e\u003ca class=\"mw-file-description\" href=\"https:\/\/en.wikipedia.org\/wiki\/File:Sigma_lens_fungus.jpg\"\u003e\u003cimg data-file-height=\"4000\" data-file-width=\"6000\" srcset=\"\/\/upload.wikimedia.org\/wikipedia\/commons\/thumb\/d\/da\/Sigma_lens_fungus.jpg\/330px-Sigma_lens_fungus.jpg 1.5x, \/\/upload.wikimedia.org\/wikipedia\/commons\/thumb\/d\/da\/Sigma_lens_fungus.jpg\/440px-Sigma_lens_fungus.jpg 2x\" class=\"mw-file-element\" height=\"147\" width=\"220\" decoding=\"async\" src=\"https:\/\/upload.wikimedia.org\/wikipedia\/commons\/thumb\/d\/da\/Sigma_lens_fungus.jpg\/220px-Sigma_lens_fungus.jpg\"\u003e\u003c\/a\u003e\n\u003cfigcaption\u003eLens from a wide-angle lens, completely overgrown with threads of fungus on the rear element\u003c\/figcaption\u003e\n\u003c\/figure\u003e\n\u003cp\u003eThe fungi that attack surfaces belong to the groups of water mold (\u003ca title=\"Oomycetes\" class=\"mw-redirect\" href=\"https:\/\/en.wikipedia.org\/wiki\/Oomycetes\"\u003eOomycetes\u003c\/a\u003e) and sac fungi (\u003ca title=\"Ascomycota\" href=\"https:\/\/en.wikipedia.org\/wiki\/Ascomycota\"\u003eAscomycota\u003c\/a\u003e, especially the\u003cspan\u003e \u003c\/span\u003e\u003ca title=\"Fungi imperfecti\" href=\"https:\/\/en.wikipedia.org\/wiki\/Fungi_imperfecti\"\u003efungi imperfecti\u003c\/a\u003e). \"The lens fungus\" is not a specific type of fungus.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cdiv class=\"mw-heading mw-heading2\"\u003e\n\u003ch2 id=\"Prevention\"\u003ePreventio\u003c\/h2\u003e\n\u003c\/div\u003e\n\u003cfigure class=\"mw-default-size\" typeof=\"mw:File\/Thumb\"\u003e\u003ca class=\"mw-file-description\" href=\"https:\/\/en.wikipedia.org\/wiki\/File:Camera_dry_cabinet.jpg\"\u003e\u003cimg data-file-height=\"5923\" data-file-width=\"3949\" srcset=\"\/\/upload.wikimedia.org\/wikipedia\/commons\/thumb\/6\/62\/Camera_dry_cabinet.jpg\/330px-Camera_dry_cabinet.jpg 1.5x, \/\/upload.wikimedia.org\/wikipedia\/commons\/thumb\/6\/62\/Camera_dry_cabinet.jpg\/440px-Camera_dry_cabinet.jpg 2x\" class=\"mw-file-element\" height=\"330\" width=\"220\" decoding=\"async\" src=\"https:\/\/upload.wikimedia.org\/wikipedia\/commons\/thumb\/6\/62\/Camera_dry_cabinet.jpg\/220px-Camera_dry_cabinet.jpg\"\u003e\u003c\/a\u003e\n\u003cfigcaption\u003eDry cabinet for cameras and lenses\u003c\/figcaption\u003e\n\u003c\/figure\u003e\n\u003cp\u003eProper storage of optical devices can prevent fungal growth.
