Vello Manual Extension Tube Set for Nikon F-Mount

The Vello Manual Extensions Tube Set for Nikon F-Mount allows your lens to focus closer than its normal minimum focusing distance. By placing distance between your camera body and lens, the focusing distance is shortened and magnification is increased. Extension tubes enable macro performance for lenses not otherwise able to focus that close, and are also suited for close-up portraiture. The Manual Extension Tube Set for Nikon F-mount contains three extension tubes of 7mm, 14mm, and 28mm lengths. They pair up with the required camera and lens adapter mounts, which add an additional 15mm to the actual extension tube lengths. The extension tubes can be used individually or together in seven distinct combinations to create the desired magnification. For closer focusing use the larger extension tube or stack the tubes together. Extension tubes have no optical elements so do not degrade the quality of your lenses.
