The digital macro filter kit includes four close-up diopters of +1, +2, +4 and +10 magnification with a 67mm thread for easy screw-on attachment, effectively transforming your lens into a crisp macro lens.
You can combine diopters to multiply magnification effect and add other filters for additional effects.This 67mm Three-Piece Solid Neutral Density Filter Kit from Vivitar contains three filters that can be used individually or in various combinations to create a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.
The 67m filters are manufactured from high quality solid optics. Each individual filter is heat treated and coated to avoid any rare movement or distortion.
