Get extra wide angle shots with the Cokin Magne-Fix 0.35x Wide-angle Lens. The Cokin Magne-Fix lens features a magnetic attachment instead of a thread so that it can be used with many unthreaded camera lenses. To attach the lens, a unique magnetic ring sticks around the camera lens and holds the wide-angle lens onto the camera body. The magnetic ring can remain permanently on the camera, or can be easily removed if necessary.
Note: Tests have been made to ensure that the magnetic system does not create interference with cameras or phone devices.
