• As with all macro photography, images will have a very shallow depth of
eld. To increase the depth of eld, select a smaller aperture.
• Due to increased exposure times, a tripod and cable release or remote
control is always recommended for macro photography.
• Closer focusing can be achieved by using the larger extension tubes
or by stacking the tubes.
• Due to the incre ased distance between the lens and the sensor, the
camera's TTL system may not always be accurate. Use a manual
exposure mode if this h appens.
TIPS FOR USING THE VELLO EXTENSION TUBES PRECAUTIONS
• At extremely close distances, focus may be dif cult to achieve, whether
using 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 lens
forward or back to achieve the sharpest focus.
• When using extension tubes, an on-camer a ash is not recommended
since it m ay result in unsightly shadows. For best results, use an
off- camera ash, dedicated macro light , or another light source.
Note: There is no electronic aper ture control when the extension tubes are
used with Nikon AI lenses.

• Using an extension tube provides extremely close focus for your lens,
but you will not be able to focus to innity while the ex tension tube is
attached to your lens.
• The amount of tr ansmitted light is reduced when using an extension
tube. The light is reduced more when multiple extension tubes are used
together. This reduction in transmitted light c an affect the camera's
ability to auto focus. Manual focusing is recommended if the lens begins
to "hunt" for a focus point (when it’s not able to quickly lock onto the
subject).
