The Rodenstock HR Digaron Macro 105 mm f/5.6 is a macro lens 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 lens element group (floating elements) is shifted for a perfect matching of the optical design to the respective imaging scale. The lens therefore produces a high resolution, exceptional contrast, and a minimization of chromatic aberration (colour fringes) unsurpassed in the macro sector.

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.

The default focussing range is 25mm from infinity which results in a ratio upto 1:4

  • with an added extension of 25mm, the focus range is between 1:4 up to 1:2
  • with an added extension of 50mm, the focus range is between 1:2 up to 1:1,14
  • with an added extension of 75mm, the focus range is between 1:1.14 up to 1:1
