Shades of Blue. This 4 × 5.6 PolarPro BlueMorphic Filter (Blue) uses bright highlights, light sources, or reflections to produce anamorphic lens style light streaks without the addition of a hefty cine lens. This style filter contains blue lines within the filter to flare streaks in blue. Crafted from German optical glass, this filter is protected by 16 layers of multi-coating for protection against scratches, oil, and water. Even with the durable aluminum frame around the trim, this filter is about 50% lighter on weight than a traditional filter of this size, making it a perfect fit for gimbal-based applications.
