Novoflex BAL-EOS Automatic Bellows for Canon EF mount

Novoflex BAL-EOS; automatic bellows unit for Canon EF mount

The classic way to macro and micro photography is through the bellows. The fully automatic bellows BAL-EOS has been specially designed for use with Canon EOS SLR cameras and lenses and transfers all functions between camera and lens. Suitable lenses can even be attached to the bellows in retro position using an optionally available reducing ring. The BAL-EOS automatic bellows is of course fully integrated into the NOVOFLEX adapter system and can also be used with other lenses for special applications. Every photographer is free to choose which lens to use with the automatic bellows. However, if you are looking for the best possible image quality, you will be happy with the FLEX-APO-DIGI90. This is a high-resolution and apochromatically corrected lens head, which is available as an option. In addition to the excellent imaging quality, this optic offers an amazingly wide focusing range that extends from 1:1 to infinity. Even those who prefer to work with manual objectives do not have to do without the NOVOFLEX automatic bellows, because, as usual with NOVOFLEX, the automatic bellows fits into the large NOVOFLEX modular system and can be combined with all kinds of NOVOFLEX accessories.

Function and task of a bellows unit in general:

• Stepless extension = distance between sensor plane and lens (=image distance); thus a continuous approach to small objects in order to be able to photograph them image-filling.
• Telephoto lenses can be focused much closer than their closest focusing distance (without bellows); thus telephoto perspective at close range and, above all, long working distance (no disturbance of the object, space for additional lighting).
• With the standard and especially wide-angle lenses (from the camera range) enlarged images = macro images; over 1:1 to approx. 7:1
• On the tripod: an optionally available adjustment slide is used for focusing without moving the bellows extension (=image width) or the tripod; i.e. the focus zone can be relocated while the magnification remains constant.
