2-in-1 Variable ND and CPL Filter for 58mm Lenses This versatile filter combines variable neutral density (ND) and circular polarizing (CPL) effects in one convenient package. It's designed for lenses with a 58mm thread size. Key features: • Variable ND effect from ND2 to ND32 (1-5 stops of light reduction) • CPL effect to reduce reflections and enhance contrast • Self-locking technology minimizes vignetting on wide-angle lenses • Premium optical glass for high-definition image quality • Multiple nano-coatings for water, oil, and scratch resistance • Aircraft-grade aluminum alloy frame with non-slip texture • Laser-etched markings for precise ND adjustment The variable ND feature allows you to control exposure in bright conditions, enabling slower shutter speeds or wider apertures for creative effects like motion blur. The CPL function helps reduce glare from reflective surfaces such as water or glass, while also enhancing color saturation. With its ultra-slim design and multiple resistant coatings, this filter is both practical and durable. The high-quality optical glass and nano-coatings minimize flare and ghosting, ensuring optimal image quality. Compatible with all 58mm thread size lenses. Please verify your lens thread size before purchase. The size is typically marked on the front or side of your lens with a diameter (?) symbol. Includes: • 1 x 58mm 2-in-1 ND CPL Filter • 1 x Protective Case • 1 x Cleaning Cloth Note: This filter has a slightly larger front diameter. For lens caps or hoods, a 62mm size is recommended (sold separately).
