Description
The Ironglass Vintage Soviet Mark II lens set has been fully rebuilt, with every mechanical part upgraded for precise operation, improved reliability and standardised gear positioning across the set. A 15-blade aperture delivers smooth, cinematic bokeh.
Hybrid Focus System
A hybrid focus system combines a refined helicoid with CAM-driven technology for rugged, reliable control. Internal focusing no longer restricts clip-on matte box use, giving more flexibility on set.
