CinemaScope Aspect Ratio Anamorphic Characteristics The stretched oval bokeh and blue lens flares, which are hard to fake in post, bring a unique cinematic look and feel to the film. Stunning Image Quality This lineup outperforms its rivals in maximum aperture, sharpness, and distortion control while still maintaining the anamorphic artistic aesthetic. Compact & Lightweight Throw the lens on lightweight setups, for example, a gimbal, to explore flexible angles that cannot be achieved by traditional bulky anamorphic lenses.
