This item is an accessory. It must be rented with a non-accessory item.
These filters reduce the amount of light passing through the camera lens without changing the color of the scene. They are especially useful in mid day bright sun to help prevent overexposer. Filters also allow proper exposer at a wide aperture for reduced depth of field to highlight a key subject by making you foreground or background out of focus.
Please note that filters must be ordered with other items and not alone.
