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).

Congratulations on purchasing this high-performance Rodenstock lens. We

are condent you will enjoy all the features this macro lens can offer you:

it is continuously optimizable for any imaging scale between 1:3 (β′ = -0.3)

and 3:1 (β′ = -3) and thus offers an imaging quality that puts all that has

gone before it into the shade. The sharpness is only limited by the physi-

cally unavoidable diffraction, the distortion is extremely low, reduced to

almost zero from a scale of 1:1, and color fringes are a thing of the past.

Conventional macro lenses suffer from typial shortcomings

Lenses are always optimized for an imaging scale that depends on the in-

tended area of use. Optimization is usually carried out for innity (β′ = -0).

Less frequently, but almost always for technical lenses for studio photog-

raphy, optimization is carried out for a scale of 1:20 or 1:10 (β′ = -0.05 or

β′ = -0.1), which corresponds to a distance of around 20 times to 10 times

the focal length. With different scales or different distances, the imaging

quality rst reduces by a small amount and then more and more. This ap-

plies to the sharpness and equally to the distortion, the color fringes and

other aberrations. A larger value, e.g. 1:3 (β′ ≈ -0.3), is selected as the

optimization scale for macro lenses and an optical design is chosen that

keeps the sharpness drop relatively small over a wide scale range. Irritat-

ing aberrations nevertheless become visible when high demands are made

and when the scales differ more from the optimum, above all when the

distance setting should reach up to innity (β′ = -0).

The HR Digaron Macro 105 mm f/5.6 is totally uncompromising

The Rodenstock HR Digaron Macro 105 mm f/5.6 has not been optimized

for a xed scale in order to avoid such compromises. The lens can rather

be individually and continuously optimized for every shot within the range

from β′ = -0.3 to β′ = -3 using a rotating ring by displacing an internal lens

element group (“oating elements”). This delivers exceptional image

quality without any compromises toward either end of the recommended

scale range from 1:4 (β′ = -0.25) to 4:1 (β′ = -4). The rotating ring should

be set to β′ = -0.3 for scales below 1:3 and to β′ = -3 for scales above 3:1.

The HR Digaron Macro, that is superior to all other lenses from around 1:4,

can even be used up to innity (β′ = -0) with only small losses in quality.

The scale bar from β′ = -0.3 to β′ =

-3 for positioning the oating ele-

ments can be found directly behind

the orange ring with the associated

black index line. The scale is set to

-1.00 on the photo shown at the

side. We have prepared scale mea-

surement cards for all relevant sen-

sor sizes to enable you to make an

exact determination of the scale to

be set for your macro shots. How-

ever, some measurement cards are

too large to be included inside the

box of this lens without being fol-

ded. But you can download a PDF

(2 DIN A4 pages) of the cards from

www.rodenstock-photo.com/measuring.pdf

Simply print the page with the measurement card that matches your sen-

sor size (the sensor width in landscape format is indicated in a black rect-

angle) on DIN A4 paper of cardboard thickness. If you use a transparent

adhesive foil to laminate the card, the measurement card cut-out along

the frame will be more stable and will also remain clean longer. The mea-

surement card for the sensor format 24 mm x 36 mm is shown below:

How to nd the right image scale to be set

Arrange the motif and the lighting as usual. Before you check

the image on the monitor of the camera, of the digital back,

of your tethered computer or on the screen of a technical

camera, you can rst roughly estimate the imaging scale to be

set at the rotational ring or simply set it to β′ = -1.00.

Once you have decided on the motif design, simply hold the

measurement card matchin in the sharpness g your sensor size

plane of your motif such that the left edge contacts the left

image margin in landscape mode. You can now read the imag-

ing scale off the bar at the right hand image margin. It is usu-

ally sufcient to make an estimate directly at the motif. For

more precision, read the scale value off the monitor or off the

ground glass screen. In portrait mode, hold the measurement

card vertically at the lower image margin and read the scale

from the upper margin (in the example below β′ ≈ -0.45).

Alternatively, you can measure the motif working distance

from the front lens ed and read the scale from this barge

You can set this scale at the rotational ring (set to the respec-

tive end position if the range -0.3 to -3 is exceeded) and can

either use the focusing mount or the bellows extension or use

a camera movement to refocus to maximum sharpness.
