Neewer 52mm 2-in-1 Variable ND2-ND32 & CPL Filter HD Optical Glass 30-Layer Nano Coated No X Cross

The Neewer 2-in-1 Variable ND2-ND32 and CPL Filter allows photographers to combine the functions of a neutral density filter and a circular polarizer filter in a single unit. It's ideal for shooting in bright conditions, enabling motion blur effects and reducing reflections and glare from non-metallic surfaces like water or glass. The variable ND function reduces 1–5 stops of light.

Key Features:
* **Variable ND & CPL Functionality:** Simultaneously adjust light reduction (ND2-ND32) and polarization to control exposure and reflections.
* **No Dark Cross Shadow:** Features self-locking technology to prevent vignetting or dark cross shadows, especially when used with wide-angle lenses.
* **HD Optical Glass:** Constructed with high-quality HD optical glass and 30 layers of nano coatings on both sides for less than 0.1% reflectivity, reducing flare and ghosting.
* **Multiple Resistant Coatings:** Protects the filter from water, oil, dust, and scratches, ensuring durability and clear images.
* **Aircraft Grade Aluminum Alloy Frame:** CNC machined aluminum alloy frame with a non-slip texture for easy installation and removal. Laser-etched marks provide precise control over light reduction.
* **Ultra Slim Design:** Features a slim profile, with a front diameter slightly larger than the back (Note: requires a 55mm lens cap/hood).
* **Compatibility:** Designed for lenses with a 52mm thread size. Please verify your lens thread size (marked with a "Φ" symbol) before purchase.
