Manufacturer description #1

The Focabell is a bellows-type focusing device intended primarily for taking close-up pictures. It focuses over an extreme range very quickly and conveniently. There are two provisions for changing the focus, one for rapid shifts and one for critical adjustments. The Focabell is made with fine precision, is very rigid, and will be found to the most satisfy exacting requirements. In addition to MIRANDA lenses, lenses of other makes can be used with adapters. Telephoto lenses in short mounts can be focused from infinity; other lenses only for close-up photography. The Focabell truck is engraved with magnification scale (for 50mm, 58mm normal and 135mm short barrel lens). The Focabell can be mounted on the AUTOMEX in either vertical or horizontal format.

Manufacturer description #2

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.

A deluxe type of extension bellows unit, with double track and rack-and-pinion for speedy movements and a precision focusing device.

• Pushing a lever on its right side permits the bellows to slide forward, pulling it back locks the bellows firmly.
• Between the two tracks is a scale giving magnification ratios and exposure factors, black figures on one side for the 50mm lens and red figures on its reverse for the short-barrel 135mm lens. This scale can be detached by removing a screw and reattached to indicate the side which matches the lens being used.
• Magnification ratio is 1~2.6 times with 50mm lens and infinity~0.6 times with short-barrel 135mm lens. The figures on the scale show magnification ratios at top and exposure increases at bottom.
• The magnification ratios are read off from the position indicated by the tip of the precision focusing device.
