On most lenses,tthat manufacturers provides a focusing mechanism that extends
only a few millimetres, partly to keep down cost and also to restrict the
lens to extensions for which its optics are optimised. To provide additional
extension,you can add one or more extension tubes between the camera and the
lens, to make the lens focus at closer distances and it can produce higher
magnification.
This Macro Extension Tube Set for Canon EOS film & Digital SLR,it
includes 3
extension tubes - 9mm, 16mm, 30mm adapters and a male & female adapter.
You
can mount the tubes between lens and camera body to get your choice of macro
ranges. Totally it is 8 combinations. They fit directly to the body of the
camera without the other adapter. Very easy to be used: just place it on the
body of the camera as the lens and put the lens on tube.
When using the extension ring with a Canon body, the camera should be set in
the ?M? mode.The macro extension tubes is fit for the Canon EOS cameras

Use this set,it will not downgrade the optical quality of your lens.
Sharpness and Saturation can be still maintained. But they are not meter-
coupled. They do not preserve the automatic diaphragm. It should be used with
manual lenses with their own aperture dial. There is no electronic connection
between the body and the lens. Automatic lenses can be used with their widest
open aperture only.

One macro tube set.
