Vello AF EXTENSION TUBE SET User Manual page 9

TIPS FOR USING THE VELLO EXTENSION TUBES
• As with all macro photography, images will have a very shallow depth of field.
To increase the depth of field, select a smaller aperture.
• Due to increased exposure times, a tripod and cable release or remote is always
recommended for macro photography.
• Closer focusing can be achieved through using the larger extension tubes or
by stacking the tubes.
• Due to the increased distance between the lens and the sensor, the camera's
TTL system may not always be accurate. Use a manual exposure mode if this
happens.
