Hi All, Does this look like fungus, or its just greasy or dusty? I had taken this photo at night, with light source shining indirectly from behind the lense. First picture - my 14 mm F2.5 lense Second picture my 14 mm F2.5 lens, doesn't this second picture look very blurry? Third picture - my 20mm F1.7 lens. All of these photo are taken handheld, with me holding the lense and the camera. Used 20mm lens to snap photo of 14mm lens, vice versa.
