At extremely close distances, focus may be dicult to achieve, whetherusing
auto or manual focus. If this is the case, use a macro focusing rail or set the
lens manually to the desired focus point. Then, move the lensforward or back
to achieve the sharpest focus.

When using extension tubes, an on-camera flash is not recommended since
it may result in unsightly shadows. For best results, use an o-camera flash,
dedicated macro light, or another light source.
Note: There is no electronic aperture control when the extension tubes are used
with Nikon AI lenses.
