Multi-coated to prevent internal ghosting and reflections

• Compatible with the built-in rear filter slot of a Tamron SP 15-30mm f/2.8 Di VC USD lens for Canon EF

• Darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required

• Providing a respective 3, 4, 6, and 10-stop exposure reduction, these filters allow you to control depth of field and convey movement more easily

• Filters do not affect the coloration of the image and are ideal for use with other filters

• Constructed from optical glass for clarity as well as color fidelity

• Nano coatings provide an additional layer that results in an improved beading effect when in contact with water or oil for greater cleaning efficiency

• Plastic filter case for storage and transport
