The Sony E-mount macro extension tube, designed for Sony E-mount cameras. This extension tube is placed between the camera lens mount and the lens, turning your lens into a macro lens. By moving the lens forward, you can shorten the minimum focusing distance, allowing you to use almost any lens as a macro lens.
 

This product does not support autofocus, so you need to focus by moving the camera backward or forward until the subject is in focus. Before installing the lens on the adapter, you also need to ensure that the lens aperture is set to the maximum, as it cannot be changed afterwards.

The example images were taken using the Sony A6000 and the Sony 16-55mm kit lens, which has a minimum focal length of about 25cm. After using the adapter, the minimum focal length at the widest focal length is close to 5mm.

When printing, you need to set the filling parameter to 4 layers, with a filling rate of about 15-20%, to avoid light leaking into the adapter. It is recommended to use black ink for printing, but I didn't encounter any problems when using white ink for printing.
