Practical Tips
•
The exposure increase is already taken into account for cameras with internal mea-
surement (TTL).
•
Turn off the autofocus of your camera or lens as it will overdrive in most cases. Fo-
cusing in the macro range is usually done by changing the lens-to-object distance.
•
Since the current lens designs are extremely diff erent today, it is no longer possible
to establish a general relationship between bellows extension and magnifi cation.
Nevertheless, to determine the magnifi cation individually for your system, proceed
as follows:
Use the desired bellows extension, photograph vertically a ruler and determine the
width of the image in mm. Now divide the sensor width of your camera by the thus
determined value.
Example: With a full-frame camera (36mm sensor width) and 18mm image width,
you have a magnifi cation of 2: 1 (36: 18 = 2: 1)
•
The included RETRO reverse adapters can also be used without the bellows unit
to mount a lens in retro position directly on the camera.
•
Using manual lens heads, magnifying lenses or lenses with the 39 mm Leica thread
is possible for special purposes. For this, adapter rings are available as optional ac-
cessories. We are happy to advise you in this regard!

Product Description
The automatic bellows BALCAN-AF enables Nikon Z photographers to penetrate the near and
macro range while retaining all the control functions of their camera. All electronic functions and
information are transferred between the camera and the lens. The BAL-NIKZ is suitable for all
cameras of the Nikon Z system and for all Z-Nikkore (maximum diameter lens: 90mm). The lens
can be mounted in normal position or in retro position on the front standard. In the latter case,
a stepping ring (see page 7) is required, in case your lens has a fi lter diameter other than 58mm.
The automatic bellows unit consists of the reverse adapters NIKZ-RETRO with camera connec-
tor (1), lens connector (4) and connecting cable (8), the bellows unit BAL-F with drive knob (10)
and locking knob (7) and the two adapters RETRO-FLEX (2) and FLEX-RETRO (5) connect-
ing the reverse adapters to the bellows unit. With the help of the Locking screws (3) and (6), each
two times available, the two adapters are attached to the rear- and front standard of the bellows.
The bellows extension can be changed with the drive knob (10) while the locking knob (7) is
open. By tighten up the locking knob (7) the extension is fi xed. For reproducible work, the guide
rail scale, which shows the bellows extension, can be seen from above.
The bellows unit is equipped with a dovetail guide (11) for direct mounting on a NOVOFLEX
quick-release of the Q=System (ARCA / UNIQ/C compatible). The safety pin of a NOVO-
FLEX quick-release engages into the milling cut-out and prevents unintentional slipping out of
the rack if the corresponding clamping screw was accidentally not fully tightened. Alternatively,
the 1/4 “or 3/8” threaded holes (13) or (14) can be used for mounting on a focusing rack or tripod
head. The installation of a video-pin (threaded hole 12) serves as anti-twist protection.
