The extension tubes increase the distance between the lens and the image sensor, effectively extending the lens's focal length. This shortens the minimum focusing distance and allows for closer shooting distances. This is ideal for macro photography, where precise close-up focusing is essential. The three extension tubes of 7 mm, 13 mm, and 37 mm, along with two bayonet rings, can be combined in any configuration, depending on the desired shooting distance and magnification ratio.

Please note that the extension tubes interrupt communication between the camera and the lens, so settings must be adjusted manually on the lens. Package includes: 1x walimex macro extension tube set for Nikon, consisting of three extension tubes and two bayonet rings.
