Rodenstock / ALPA Macro Switar 5.6/105 mm
Rodenstock / ALPA Macro Switar 5.6/105 mm - custom made for ALPA by Rodenstock; without shutter to be combined particularly with ALPA 12 FPS; recommended reproduction scale 1:4 to 4:1; optimizable by continous adjustment ring from scale 1:3 to 3:1; V Groove adaptation to ALPA universal bellow or to individually assembled extension tubes.
Red Dot - Best Azimuth
The V Groove mount allows mounting the lens "rotating". This fact is very favorable for this type of optics as the optimal lens orientation can easily be achieved. Rodenstock determines this optimal position once the lens is finally assembled and adjusted. This optimal position is indicated with the removable dot you find on a brand-new lens. When mounted this red dot should point to the 12 o'clock position.
