Unique Cinematic Rendering

What sets this lens apart is its oval aperture modification, which produces an anamorphic-style oval bokeh. Unlike standard spherical lenses, this mod delivers the cinematic depth and oval out-of-focus highlights often associated with expensive anamorphic glass. By simply applying 2.35:1 letterboxing in post-production, you can achieve an authentic widescreen anamorphic look without needing to de-squeeze footage.

Other cinematic qualities include:

• Swirly Bokeh & Character – Classic Helios rendering adds personality to every frame.
• Smooth Focus Transition – Perfect for controlled rack focusing in dramatic scenes.
• Neutral Oval Bokeh – Emulates anamorphic background blur with spherical sharpness.
• Vintage Contrast & Warm Tones – Creates an organic film-like image with natural colors.
