Kit Includes 3 Items with all Manufacturer-supplied Accessories + Full USA Warranties: 1) Vivitar Macro Extension Tube Set (for Nikon Cameras) 2) Precision Design Deluxe Lens Pouch - Small (up to 5 in / 12.7cm) 3) Precision Design 6-Piece Camera + Lens Cleaning Kit Vivitar Macro Extension Tube Set for Nikon AF DSLR Cameras Increase your macro photography capabilities. The Vivitar Macro Extension Tube Set is designed specifically for use with Nikon DSLR cameras and lenses ranging from macro to semi-telephoto, and allows the photographer to enable a lens to focus closer than its normal set minimum focusing distance. Getting closer has the effect of magnifying your subject (making it appear larger in the viewfinder and in your pictures) . They are exceptionally useful for macro photography, enabling you to convert almost any lens into a macro lens at a fraction of the cost while maintaining its original optical quality. These extension tubes have no optics. They are mounted in between the camera body and lens to create more distance between the lens and film plane. By moving the lens father away from the film or image sensor in the camera, the lens is forced to focus much closer than normal. The greater the length of the extension tube, the closer the lens can focus. This set contains three tubes of different length - 12mm, 20mm and 36mm - which can be used individually or in any combination to obtain the desired magnification. These extension tubes are designed with all the circuitry and mechanical coupling to maintain auto focus and TTL auto exposure with most Nikon lenses, given there is enough light to activate the cameras AF system properly.
