Cinematic Aspect Ratio

This 1.33x anamorphic lens compresses the image horizontally during capture, which is then de-squeezed in post-production or by compatible camera monitors to achieve a wide 2.35:1 aspect ratio from a standard 16:9 sensor. This creates a distinctive cinematic look.

Flare Characteristics

The lens is available in two flare options: Blue Flare and Neutral Flare. Blue flares are suitable for sci-fi, mystery, and music video scenes, while neutral flares adapt to the color of the light source, ideal for commercial, interview, or emotional shooting scenarios.
