PRECAUTIONS
• Using an extension tube provides an extremely close focus for your lens, but
you will not be able to focus to infinity while the extension tube is attached
to your lens.
• The amount of transmitted 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 can 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).
• Please read this instruction manual before using this product.
• Images are for illustration purposes only.
