- High quality aluminum filter ring helps to prevent jamming and provides additional strength.
- Constructed from high quality level of Schott glass for optical clarity. Digital water proof and scratch resistant multi-coating offers both protection to the glass and helps to improve light transmission and image quality.
- The slim filters are specifically designed for use with wide angle lenses.
- Light rays which are reflected by any surface can become polarised so polarising filters are used to select which light rays enter your camera lens. CIRCULAR PL filters allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. They also enable colors to become more saturated and appear clearer with better contrast. This effect is often used to increase the contrast and saturation in blue skies and white clouds. Air's polarising filters do not affect the overall color balance of a shot.
ifilter Air range of filters build on their previous very successful filters. The Air range are manufactured using same level of Schott glass (Schott glass is used in B&W & Heliopan filters). The multi coating features: Anti-glare. Anti fouling (repels oil, water etc). Scratch resistant. These coatings mean: Easy Cleaning. Reduced reflections to help prevent glare and ghosting. Fantastic durability. The filter ring is coated using an Anodic oxidation matte black to greatly reduce reflections. SPECIFICATIONS: Filter Size: 49mm. Frame Profile: Slim. Double Threaded: Yes. Multi-Coated: Yes (3 Coatings). Optical Material: Quality level of Schott Optical Glass. Frame Material: Slim Aluminium.
