Fast Ekran 18mm lens 35OKS7-18-1 (f/1.4, T/1.6)
18mm Ekran fast lens for Konvas, Kinor (OCT-19 mount). Focuses from 0.25m.
Very good used condition. Aperture ring works well. Focus ring is bit tight - relubrication may help, though the lens can be used as is. Actually, the lens was tested at a film studio and used in production recently (in May, 2011).
Glass is clean. No fungus, no scratches. Few minor cleaning marks, and few dust particles inside.
The lens can be used with different DOF systems, RED, modern DSLR cameras if you have corresponding adapter.
