The wider the ring, the shorter focusing distance to the object. That is why Kenko Extension Tube Set comes with 10mm and 16mm tube rings. You can use it separately, or together. Kenko Extension Tubes for Full Frame SONY E-mount mirrorless cameras have electronic contacts to provide Auto Focus and EXIF data corresponding between camera and lenses.

Kenko adopted electrostatic flocking finish on the inner surface of the extension ring – the most effective technology ever known to minimize internal reflections, romping light rays and flares. Kenko electrostatic flocking is a mass of short (0.3mm -0.5mm) synthetic fibers that are adhered by static electricity on the fabric and reinforced by coating that prevents fibers from falling out.

Use the ring the width of which does not exceed focal length of the lens used. If the width of the ring (or rings combination) exceeds the focal length of the lens used, it will be impossible to focus on the object.

Due to the extremely shallow depth of field, it is recommended to use manual focus.
