Weight: 125g, 85g and 60g
Full TTL coupling and AF (light levels permitting)
Please note: The Kenko Auto Extension Tubes are not auto focus compatible with Nikon AF-s (Silent Wave) lenses, manual focusing is required with these lenses.
Kenko's Auto Focus extension tubes are designed with all the circuitry and mechanical coupling to maintain auto focus and TTL auto exposure with most Canon, Nikon, and Sony/Minolta AF lenses, given there is enough light to activate the cameras AF system properly. Pentax fitting must be used in manual focus.
Extension tubes are mounted in between the camera body and lens to create more distance between the lens and film plane. By increasing the distance between the lens and the film/sensor the lens is forced to focus a lot closer than normal. The greater the length of the extension tube, the closer the lens can focus. You will lose some light when using the extension tubes, especially when stacking the tubes together. The light lost can affect the camera's ability to Auto Focus, in this situation it is recommended to Manual focus instead.
