Description
The two main functions of a UV filter are:
1. **Protection**: A UV filter protects the front element of the lens from:
* Fingerprints and oils
* Dirt, dust, and mud
* Accidental scratches and chips
* Provides a physical barrier to prevent damage to the lens
2. **Optical enhancement**: A UV filter can also enhance the picture quality by:
* Filtering out UV light, which can cause a bluish color cast in images
* Reducing haze in images
* Improving contrast for a clearer picture
The specific features of this 43mm UV filter include:
* Made from Japanese glass
* Multi-coated to prevent fogging and improve performance
* Blue coat for high transmittance and low reflectivity
* Slim profile to minimize dark corners when shooting at wide angles
