12 aperture blades for a circular pupil and a perfect bokeh
The HR Digaron Macro 105 mm f/5.6 with 8 lens elements in 4 groups not
only stands out due to its exceptional sharpness, but also due to a per-
fect bokeh thanks to an almost circular aperture with 12 aperture
blades, even when stopped down: light spots outside the depth of eld
are reproduced as homogeneous circular circles of confusion.
Stop down only as far as needed for the wanted depth of eld
!
Because the resolution of this high performance lens is incredibly close
to the diffraction limit, you should always only stop down by as much as
the necessary depth of eld requires. Stepping down does not increase
sharpness (this is already optimum with a full aperture), but produces
diffraction that reduces contrast and resolution. Please remember that
the aperture in the macro range becomes much smaller than effective
for far distances. At a scale of 1:1, the nominal f-number 5.6 becomes an
effective f/11; at a scale of 2:1, it becomes f/16; and at a scale of 3:1,
even f/22. This is why the aperture setting is deliberately limited to the
smallest nominal aperture of f/16.
Suitable for technical cameras, SLR and other system cameras
The large image circle of 82 mm diameter is big enough for even the
largest sensors of professional digital backs and still has sufcient re-
serves for camera movements (parallel shift and/or lens tilt). At the
same time, the exceptional sharpness exceeds that of classical macro
lenses both at very high resolution digital backs and at smaller system
camera sensors (with even smaller pixel pitches in some cases).
The matching to different camera systems takes place using specic
adapters on the V groove interface. Since the optical design of the lens
does not permit a leaf shutter, the camera or the digital back has to
have a focal-plane shutter or a sensor with an electronic shutter.
Focusing can take place by changing the distance from the motif or from
the sensor. The latter is done using a bellows, using the bellows exten-
sion of the camera or using extension rings (with a xed imaging scale)
and a helical focusing mount (for continuous scale changes).
