The Cokin Filter A705 Cyan CC (CC30C) is a professional camera filter designed for precise color correction and creative photography applications. This cyan color correction filter, designated as CC30C, features a 30% cyan density suitable for adjusting color temperature and balancing artificial lighting conditions in photographic and videographic work. With the A705 series designation, this filter is engineered for compatibility with Cokin's A-series filter holder system, offering photographers a versatile tool for landscape, portrait, and studio photography.

The filter construction utilizes high-quality optical glass with multi-layer coatings to minimize reflections and maintain image sharpness while providing consistent color transmission across the visible spectrum. Measuring approximately 67 mm in diameter with a standard 1 mm thickness, this filter is designed for durability with a scratch-resistant surface and aluminum alloy frame that resists bending and corrosion.

The cyan color correction properties make this filter particularly useful for compensating for excess red light in tungsten or fluorescent lighting environments, allowing photographers to achieve more accurate color reproduction without extensive post-processing. For digital photographers, this filter can be used creatively to introduce cyan tones for artistic effects or to correct color casts in specific shooting conditions.

The filter maintains excellent light transmission characteristics with minimal impact on exposure values, typically requiring an exposure compensation of approximately one-third stop. Compatible with lenses ranging from wide-angle to telephoto when used with appropriate filter holders, this product represents a professional-grade accessory for photographers seeking precise color control through optical filtration rather than digital manipulation. The filter comes in protective storage packaging to prevent damage during transport and storage.
