Abstract
A magnetic lens filter system includes an external rotational element having a plurality of ridges allowing a photographer to grip and rotate the external rotational element. A plurality of gears is in engagement with the external rotational element, and an inner gear connected to an inner rotational element such that when the external rotational element is rotated the inner rotational element rotates. Advantageously, a rotatable magnetic element is configured to rotate simultaneously with the inner rotational element. The system is configured to accept a removable lens filter. The removable lens filter has a magnetic element configured to attach to the rotatable magnetic element.
