The Carl Zeiss T* UV 77mm Filter is a clear, all-purpose screw-on filter designed to protect the front element of your lens and absorb the ultraviolet rays which can often make outdoor photos hazy and indistinct. It features Zeiss' legendary T* anti-reflective coating which helps to reduce reflections and improve light transmission to ensure optimal image quality. For use with lenses that feature a 77mm thread.
Carl Zeiss T* UV Filters
- Quality - High-quality glass featuring ZEISS T* anti-reflective coating
- Flexibility - High-fit accuracy for fast filter change. Can be used with a lens shade
- Compatibility - Ideal for ZEISS lenses. Can be used with non-ZEISS lenses
- Effect - Optimal protection of the front lens element and more clarity for your photograph
Using a low quality filter optical effects might appear diminishing the quality of your picture. Especially fast lenses of long focal lengths need demanding polish quality of the filter to preserve the image sharpness. The high-quality glass is optically homogeneous and the surfaces are accurately plane to match perfectly for high-performance lenses.
All ZEISS T* UV Filters feature the T* anti-reflective coating. Special substances, one by one, are vaporized with very high energy in a high vacuum, which are then deposited on the glass surface as coatings with precisely controlled thicknesses to increase the transmission of visible light and achieve the desired reduction of reflections. The technology has been constantly improved since it was first applied by Carl Zeiss back in the 1930s.
ZEISS T* UV Filters are equipped with standard filter thread mounts with an additional front thread mount , e.g. to attach the standard lens cap. Due to their slim frame design they can be used on wide angle lenses, even on a full frame camera body, without vignetting. ZEISS T* UV Filters provide high-fit accuracy for fast filter change and can be used on lenses in combination with their dedicated lens shades.
ZEISS T* UV Filters show a very steep edge at approximately 410nm so they block UV light of shorter wavelength completely. UV Filters have a nearly constant transmission within the range of visible light (between about 410nm and 700nm). So the filter appears completely clear and does not tamper the hue.
