Hello, The Nanoha Macro Lens 5:1 for Micro 4/3 Mount Cameras from Yasuhara gives you a true macro lens for photographing at 4:1 or 5:1 magnification. A removable lighting module has 3 LEDs for lighting very small objects--this is usually necessary because the lens itself is so close as to block light from the subject. Also included are 4 plastic holders which can be mounted to the front of the lens to hold your subject and maintain a constant distance between lens and subject. These plastic holders can be easily modified by cutting them to fit your subject. Ten coated spherical lenses in seven groups reduce reflection and the sturdy mount is made of steel. Focusing range is 0.43-0.78" (11-19 mm).
