Length of the Soratama Extension Tube
Here, we will adjust the length of the Soratama extension tube (Extension Tube 72). The camera is already set to photograph in a close-up mode (using marco lens or close-up ring.)
If you have a tripod, please attach the camera onto it. The focus is set manual. By looking through view finder or the LCD display, move the soratama ball to have it focused. Then adjust the Soratama extension tube to the position where it was focused correctly.
Please use the step-up ring to attach the Soratama extension tube onto the lens. If it is not focused correctly, try to adjust the length of the tube. Once it is able to focus on both near target and the target far, you are ready to shoot.
