The Extension Tube Set for the Nikon 1 series by Caruba consists of three aluminum extension tubes with lengths of 10 mm, 16 mm, and 21 mm. These macro extension rings allow photographers to reduce the distance to their subject, achieving a higher magnification, which is particularly advantageous for detailed shots of small objects. The tubes are specifically designed for the Nikon 1 mount, ensuring a precise fit and easy handling. With a maximum magnification factor of 3x, these tubes significantly expand creative possibilities in macro photography. The silver aluminum finish not only provides an attractive appearance but also ensures a robust and durable construction. This set is a valuable addition for photographers looking to enhance their close-up skills.
