●What you need
-Camera and lens for macro photography
-Close-up lens or the macro extension tube, if your camera is not suitable for macro photography
-Paper tube or cardboard tube such as an empty snack container and lens hood
-Soratama
-Step-up ring

●Procedures
1)Cut out the flat lid from the rim. Use a cutter to cut the edge.

2)Make it suitable for macro photography. (Fix on the macro lens, close-up lens, or macro extension tube.)

3)Check the focus point by holding the soratama in front of the lens. Firstly, focus on the nearest point. Then move the soratama back and forth to focus. If you cannot focus, please further away soratama from the lens. Because the length of the lens tube will get too long, wide-angle lens or standard lens are recommended rather than a telephoto lens.

4)Cut the empty snack container. In order to draw a cutting line, wrap the container with a paper. Use a cutter to cut along the line. Do not put too much pressure. If you cut the container too short, it cannot be used. For this, cut the container long then adjust the length. 67mm step-up ring can apply to the snack “Chip Star” container’s base.

5)Place the parts in the next order. Container’s lid, soratama, container’s tube part then the step-up ring. Tape the parts for the moment and test shot to see if it is focused correctly and is not vignetted.

6)If you are satisfied with the test shot, fix the lid tightly onto the lens body. If you used the container’s bottom part, the lid will easily fall off. Wrap some paper or a thin sponge around and make sure the lid does not fall off.

●About the Close-up Lens
When using the metal frame “soratama 72” Close-up lens is not recommended because of its weight. It will put too much pressure on the lens and lead to damage. However, since the paper container tube is not as heavy as the metal soratama, close-up lens can be used.

There are several kinds of close-up lenses depending on the magnification. For the standard zoom lens, No.10 seems to fit perfectly. (There are differences depending on the lens’ focal distance.) Some Close-up lenses do not have the screw parts on the outside and cannot be fixed onto the soratama. For this, close-up lenses sold from “KENKO” are recommended.

●Step-up ring
Step-up ring is used to connect the lens and the tube. Adjust diameter of each end to the lens and the tube size. For the tube side, 67mm will fit perfectly. For example, if the lens diameter is 52mm, use the 52→67mm step-up ring.

●Make Soratama by yourself
It is possible to make soratama by yourself using acrylic plate. When drilling a hole on the acrylic plate, screwdriver is very useful. However, there are cases where the plate break apart or get cracks. Please use the drill cutting edge for acrylic objects. Also, reamers are useful to enlarge the hole.
