New Lens HR Digaron-W 32 mm f/4

Our lens series Rodenstock HR Digaron-W with an amazing resolution of 80 lp/mm and image circle diameters of at least 90 mm has been designed for the largest sensor formats up to 36x56 mm and 40x54 mm as well as for even larger stitch formats up to 49x71 mm. Now we introduce a new excellent super wide-angle lens HR Digaron-W 32 mm f/4 with an equivalent (35 mm full-format) focal length of 20.6 mm when used with a 40x54 mm sensor or of 16,5 mm when used for stitching to a format of 49x71 mm. Despite its very short focal length, it provides the same large image circle of 90 mm like the other HR Digaron-W wide-angle lenses, and it allows the same wide shift-and-tilt movements for perspective control and extended depth of field. Now, the Rodenstock lens series HR Digaron-W for large sensor formats up to 40x54 mm and stitch formats up to 49x71 mm comprises five focal lengths of 32 mm, 40 mm, 50 mm, 70 mm and 90 mm.

The HR Digaron-W 32 mm f/4 provides the following features:

  • For shift-and-tilt movements, its large back focal length of 22.3 mm leaves free space between the rear mount and the
    sensor, without touching the sensor or the rear standard.
  • The long flange focal length of 69.2 mm allows focusing at infinity with all technical cameras with a flat lens board, which makes it much easier to set the aperture and the shutter speed and permits the use of the Rollei Electronic shutter.
  • The retro-focus design causes a steeper light incidence at the margin. Therefore, the further fall-off in illumination, which is inevitable when using micro lens sensors, can be avoided.
  • Vignetting eliminated at f/8.
  • The optical effect of the sensor cover glass has been taken into account in the optic calculation for eliminating its apherical and chromatic aberration, as well as its astigmatism.
  • The high tech multi-coating ensures ultimate transmission, excellent contrast and freedom from ghost and flare.
  • A new dedicated center filter with specially matched sloping absorption will be available for the HR Digaron-W 32 mm f/4.

The HR Digaron-W 32 mm f/4 in Copal shutter size 0 is available also with the “Focus-Mount” helical focusing mount.
