1. The camera-side adapter ring RETRO-FLEX (2) is screwed into the camera connector (1) of
the RETRO reverse adapters. The camera is attached and locked accordingly.
2. The lens-side adapter ring FLEX-RETRO (5) is screwed into the lens connector (4) of the
RETRO reverse adapters. The lens is now inserted in the bayonet of the lens connector and
locked.
3. Insert both units into the connection openings of the bellows unit BAL-F and lock them with
the two locking screws (3) and (6) on the standards. Disassembly is carried out after releasing
the corresponding release button on the camera. To release the lens connector (4) from the
lens, push the release button (9) in the direction of the engraved arrow.
Operation
For close-up and macro shots, the image section (magni-
fi cation) is determined only by the length of the bellows
extension. The length can be changed with the drive
knob (10). To loosen or clamp the rack, use the locking
knob (7).
Focusing is done by changing the lens-to-object dis-
tance. With free hand shots one achieves this by chang-
ing the posture. When shooting from a tripod or on a
copy stand this is done with the help of a focusing rack.
Recommended focusing racks can be found on page 7.
Assembly of all components, lens in normal position (state of delivery)
This classic way of mounting is used with focal lengths from 50mm.

The lens in retro position on the bellows unit
This type of mounting is recommended for focal lengths of less than 50mm, as the distance to
the subject is longer than for classical installation. The lens is mounted in retro position on the
front standard
The assembly corresponds to the installation in normal position, but this time the lens and not
the lens connector is screwed into the lens-side adapter ring 58mm bellows unit (FLEX-RETRO,
5). If the lens has a diff erent fi lter diameter than 58mm, appropriate stepping rings (see page 7)
are optionally available as accessories. The lens connector (4) of the reverse adapters is inserted
into the bayonet ring of the lens.
For lenses with larger front lens diameter, a spacer is available to allow attachment to the front
standard. Alternatively, the installation can be made reversed with the lens attached to the rear
standard.
To disassemble, release the corresponding unlock button on the camera body. To dismount the
lens connector of the reverse adapters from the lens, push the unlock button (9) in the direction
of the engraved arrow. Now the lens can be unscrewed from the lens connector FLEX-RETRO
(5) of the reverse adapters.
