Operation
Carl Zeiss Attaching adapters for digital compact cameras Axiostar plus
3-26 B 40-81 e 12/01
Depending on the microscope configuration or
camera used, the distance between the
camera lens and the lens mount (3-16/6) must
perhaps be optimized (see double arrow). This
is required in particular if an untrimmed image
cannot be achieved in any zoom position of
the camera lens.
Make the following settings on the camera:
• Switch off the autofocus.
• Set the distance to ∞.
• Set the automatic exposure control to time
priority.
• Set the aperture as wide as possible (i.e.
select a small f-stop number!).
Not all cameras feature these possibilities.
Please see the operating instructions of the
camera used.
• Loosen the set screw (3-16/5).
• Vary the distance between the camera lens
and the lens mount in steps, i.e. move the
sliding mount with camera on the lens
mount by defined steps.
• Zoom camera lens from wide-angle
position (W) through to tele position (T).
• Perform test until image is format-filling
without trimming or vignetting.
• Tighten the set screw (3-16/5) again.
No untrimmed image may be obtained when a
camera adapter combination is used which is
not recommended by Carl Zeiss.
3.11.3 Attaching cameras with other
filter thread sizes
In principle, it is also possible to connect
cameras with a filter thread other than M37 or
M52. Suitable filter adapters or reduction rings
are available in photo shops. As mentioned
above, only a test can clarify whether such
cameras are compatible with the digital
adapters.
3.11.4 Sony DSC-S70, DC-S75, DSC-S85
on digital camera adapter 44
M52x0.75, 000000-1108-984
This adapter has been particularly designed for
the Sony DSC-S70. Combined with “Plan”
objectives, e.g. “Plan-Neofluar” objectives,
increased edge definition and lower distortion
can be achieved. Should future cameras prove
to be suitable, too, our sales staff will be
informed accordingly.
Attachment of the camera requires the SONY
VAD S 70 adapter ring (Fig. 3-16/2). Further-
more, the connecting piece 60-44 (456140-
0000-000) must be inserted between the
camera adapter and the binocular tube.
Make the following settings on the camera:
• Switch off the autofocus.
• Set the distance to ∞.
• Set the automatic exposure control to time
priority.
• Set the aperture as wide as possible (i.e.
select a small f-stop number!).
