Lens Data Summary

Ukrainian shift & shift/tilt lenses with Pentacon Six mount


In recent years two Ukrainian manufacturers have introduced shift and shift/tilt lens in the Pentacon Six mount.

Shift lenses

Here are the details.

Hartblei 45mm shift f/3.5 / 45 f/22 8 / 7 0.35 12 (1) 82 × 0.75 . 750
Arsat 55mm shift f/4.5 / 55 f/22 9 / 7 0.5 12 72 × 0.75 97.5 900
Hartblei 65mm shift f/3.5 / 65 f/22 6 / 5 0.5 10 (2) 72 × 0.75 . 610

Notes
(1) With this lens, some vignetting is likely to be observable on the full 6 × 6 format with shifts in excess of 10mm.  11mm & 12mm are marked in red to remind users of this.  The full 12mm of shift can be used for 6 × 4.5 format.
(2) With this lens, some vignetting is likely to be observable on the full 6 × 6 format with shifts in excess of 9mm.  10mm is marked in red to remind users of this.  The full 10mm of shift can be used for 6 × 4.5 format.

It is reported that the 45mm and 65mm Hartblei shift lenses use the optical elements of the Arsenal Mir-26B and Mir-38B, respectively.  Hartblei adds an excellent multi-coating that looks far superior to that on the original Arsenal lenses.

Arsenal in Kiev produce their own “Arsat” 55mm shift lens, which is one of the sharpest lenses available in the Pentacon Six mount.

Arsenal are now also producing 45mm & 65mm shift lenses, bearing their ARSAT brand name.  I do not know if these lenses are optically the same as the Hartblei shift lenses, but this is very probable.

All five lenses (45mm from Hartblei and from Arsat, 65mm from Hartblei and Arsat, and 55mm from Arsat only) are in mounts that rotate – so it is possible to shift down as well as up, sideways, or even in other diagonal directions if required.

All the shift and shift/tilt lenses have a manual preset diaphragm.  The 55mm shift lens has a socket for a cable release.  Using a double cable release, it is possible to automate the aperture shut-down on this lens.

Shift / Tilt lenses

Hartblei also offers three shift & tilt lenses:

45mm shift/tilt (1) f/3.5 / 45 f/22 8 / 7 0.35 12 (2) 82 × 0.75 96 × 100 850

65mm shift/tilt (1) f/3.5 / 65 f/22 6 / 5 0.5 10 (5) 72 × 0.75 . .

Notes
(1) With this lens, it is possible to shift in any direction, and tilt downward.
(2) With this lens, some vignetting is likely to be observable on the full 6 × 6 format with shifts in excess of 10mm.  11mm & 12mm are marked in red to remind users of this.  The full 12mm of shift can be used for 6 × 4.5 format.
(3) The Hartblei Super-Rotator allows completely independent rotation of the tilt and shift axes, so that you can shift in any direction and tilt in any direction to adjust the depth of field.
(4) There are other minor restrictions at full tilt, when shift against the tilt direction should be limited to 9mm.  In practice, this limitation is not likely to be significant.
(5) With this lens, some vignetting is likely to be observable on the full 6 × 6 format with shifts in excess of 9mm.  10mm is marked in red to remind users of this.  The full 10mm of shift can be used for 6 × 4.5 format.

There is reported to be another source for shift and tilt lenses in the Pentacon Six mount – the Austrian firm of Atzmueller & Rendl Linz.  For details, see the next section (link below).
