Data Sheet
High-performance macro lens for scales from 1:4 to 4:1

HR Digaron Macro 105 mm f/5.6
The Rodenstock HR Digaron Macro 105 mm f/5.6 is a macrolens that offers exceptional sharpness and that was designed
for the scale range from around 1:4 (β' = -0.25) to 4:1 (β' =-4). Unlike conventional macro lenses, it can be continuously
optimized to any imaging scale from 1:3 (β' = -0.3) to 3:1 (β'= -3) using a ring with very fine scale divisions. An internal lenselement group (floating elements) is shifted for a perfectmatching of the optical design to the respective imaging scale.
The lens therefore produces a high resolution, exceptional
contrast, and a minimization of chromatic aberration (colorfringes) unsurpassed in the macro sector.
The HR Digaron Macro 105 mm f/5.6 has an image circle diameter of 82 mm over its total scale range. It can therefore beused with both technical cameras and system cameras of all
professional sensor sizes. Even with very large sensor formats(36 x 56 mm and 40 x 54 mm) it still offers more than sufficient image circle reserves for camera movements such as parallel shift to avoid or to ameliorate converging lines and for a
Scheimpflug lens tilt to extend the depth of field without excessive stopping down.
Since the special optical design does not permit an internalleaf shutter, the camera or the digital back has to have a mechanical focal-plane shutter or a sensor with an electronicshutter. Special adapters for the V groove interface are available for connecting to the different camera systems (adjustable technical cameras, digital SLR cameras and other systemcameras). The V groove interface is an annular groove with aV-shaped cross-section close to the rear end of the mount(please see the illustration on the right side).
Focusing takes place by changing the lens distance from thesensor – using the bellows extension of technical cameras orusing an interposed bellows or extension rings or better a helical focusing mount with other cameras.
Scale measurement cards are available for a precise determination of the imaging scale to be set to optimize the image quality. They are available to download as a PDF from the Rodenstock website for all relevant sensor sizes. The scale can alternatively be read off using the measured free working distancein a diagram (see middle of page 2). The large free working
distance is also remarkable and at around 9 cm still allows
good lighting even at a scale of 4:1.

Outstanding makro lens for all sensor formats up to40x54 mm or 36x56 mm with adjustable optical image
quality optimization by a rotatable magnification scale.

The connection of the lens to different camera systems is made by specificcamera adapters using the V groove interface (an annular groove with aV-shaped cross-section close to the rear end of the mount). Because thespecial optical design of the lens does not permit a leaf shutter, the cameraor the digital back has to have a focal-plane shutter or a sensor with anelectronic shutter.

Focusing range (free working distance) and flange focal length
The imaging quality of the HR Digaron Macro 105 mm f/5.6 can be individually optimized between the scales 1:3 (β' = -0.3) and3:1 (β' = -3). With the rotating ring set to β' = -0.3, excellent results are assured up to 1:4 (β' = -0.25) and good results are still
possible up to infinity. The lens series HR Digaron-S and HR Digaron-W/SW that are optimized for the distance range only start tobecome better from a distance of around 0.5 m. The recommended range of use for the HR Digaron Macro 105 mm f/5.6
which is superior from a scale of 1:4 (β' = -0.25) is therefore from 1:4 (β' = -0.25) up to 4:1 (β' = -4). The rotational ring should
be set to the left hand end value β' = -0.3 for scales below 1:3 and to the right hand end value β' = -3 for scales above 3:1.

The best digital lenses start to experience a drop in quality
from an imaging scale of 1:4; this is where the recommended working range of the HR Digaron Macro begins.
