Kenko Macro Mellemring Tube 25 N-AF
Kenko 25mm extension tube, for those who don't know, is in a nutshell just a tube that moves the lens away from the camera's sensor, enabling it to focus closer than it would be able to without, the caveat being that you can no longer focus to infinity, and depending on the focal length of the lens used, the total focus range may not be more than an inch total. So it's used mainly, if not exclusively, for macro shooting, for much cheaper than a dedicated macro lens.

This tube has no built-in AF motor so if you are intended to use one of above bodies, AF won't work at all, manual focusing only with these bodies
