Kenko Extension Tubes are an attractive way to convert your standard lens into macro lens. The Kenko Extension Tube DG is an element without any optics. It's purpose is to move lens further from the the image sensor. The further the distance - the bigger the magnification becomes. 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, those ones you can not shoot with a standard lens only. The wider the ring, the shorter the focus distance to the object.
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 to effectively minimise internal reflections, romping light rays and ﬂares.
- Use the ring the width of which does not exceed focal length of the lens used. If the width of the ring 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.
- We therefore advise against using the two tubes together.
