6. Walimex Extension ring set for Fuji X
All-rounder in macro photography. The extension tubes can be combined in any way between the lens and the camera, increasing the distance between the lens and the sensor plane. This corresponds to a greater extension of the focusing screw. Effect: The magnification is increased, which also reduces the depth of field. A subject in close range is separated from the background and isolated. These extension tubes can be used with almost all lenses. Short focal lengths in the range of normal or light telephoto are most effective for close-up shots.
Three extension tubes for more flexibility. The set consists of three extension tubes in different sizes that can be combined in any way. This allows you to achieve significantly different magnifications with the same base lens. Please note: They extend the path of light through the extension tubes. For example, at a magnification of 1:1, the exposure time will be four times longer. For stationary subjects, we recommend using a tripod if necessary.
Contacts for data transmission. To ensure the most elegant and trouble-free operation, all three extension tubes are equipped with gold-plated contacts. This maintains the transmission of EXIF data as well as aperture control. Exposure metering in TV or AV mode is also fully possible. Finally, autofocus works flawlessly thanks to the contacts.

- To increase the distance between the lens and image plane for macro photography
- Set consisting of 3 extension tubes: 10, 16, and 21 mm
