Manufacturer description #1

This is an extension bellows unit which is used between lens and camera body for taking ultra close-up shots and magnified pictures of small objects.

• It is attached to the camera in the same way as the lens by using the outside bayonet mount and matching to the red line. But if the camera is to be used vertically, this position can be shifted 90° to match the big mark "G" which is on the camera's front plate.
• The tripod socket of Focabell can be suitably shifted to obtain proper balance.
• When combined with the short-barrel Soligor 135mm f/3.5 lens, it becomes usable over a wide range of conditions from infinity to ultra close-ups.
• As the field of coverage can be easily varied it is extremely convenient in taking pictures of animal life and scientific works.

***

Foldable compact type with single track which is light and easy to carry.

• Erect the track and set it in position by moving the small button on the focusing knob side.
• The focusing knob is on the right side, the locking knob is on the left side which is turned clockwise for locking the track.
• The magnification scale on the left side is for 0.9~2.5 times with 50mm lens, that on the right is for infinity~0.5 times with short-barrel 135mm lens. The magnification ratios can be read off from the position of the tip of track guide, which slides through the side groove of the track.
