KENKO – Macro Extension Tube Set for Sony E (Full Frame Mirroless) – 2 Tubes – 10 and 16 mm – Black

EXTENSION TUBE SET DG FOR SONY E (FULL FRAME MIRRORLESS)
Kenko Extension Tube Set DG for Sony E (Full Frame Mirrorless) cameras radically reduce the minimal focusing distance of your lens allowing you to get closer to the object. In other words: Extension Tubes convert your lens into a macro lens in a very attractive way. 
Kenko Extension Tube DG is an element without any optics. Its purpose is to move the lens further from the image sensor. The further the distance – the bigger the magnification becomes. Macro lenses are usually more expensive than standard lenses. Kenko Extension Tubes are an attractive way to convert your standard lens into a macro lens.
Kenko Extension Tubes are precisely made in Japan in order to guarantee better quality and long life of the product. Simple construction matches APC-S size and Full Frame E-mount Sony cameras. By attaching it between the camera and the lens the Extension Tube will change your lens into a macro lens without large investments in additional optical equipment. You will get close-up images, the ones you can not shoot with a standard lens only.
The wider the ring, the shorter the focus distance to the object. That is why Kenko Extension Tube Set comes with 10 mm and 16 mm tube rings.
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 an 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 (0.3-0.5 mm) synthetic fibres that are adhered by static electricity on the fabric and reinforced by a coating that prevents fibres from falling out.
