P.S.

This is great anamorphic fast zoom lens.

To have modern optical schematic with front anamorphic components.

That's why, the zoom lens have high speed F2.5

The front anamorphic components have fixed position and do not move at focusing or at zooming ( as opposed to LOMO square front glass anamorphic lenses ). The move a front compensator components only.

The modern fast and round front glass prime anamorphic LOMO lenses have similar optical schematic with front anamorphic fixed components and mobile compensator components.

 

To have high optical resolution:

40 mm zoom position - 70 lines per mm at center and 32 at corners

120 mm zoom position - 50 lines per mm at center and 18 at corners.

 

If you will change zoom position from 40 mm up to 120 mm, the optical resolution will change from 70 lines per mm up to 48 lines ( distance of focusing 4 m ).

 

 

The anamorphic factor 2x at center and 2,38x for 40 mm at corners and 1.95x for 120 mm at corner.
