Zeiss UV Filter

Graphs are in nanometers. Visible light is approximately 390 - 650 nm (the human eye can see very weakly into the 700-800nm range). Graphs used by permission.

Buying filters

A great source for filters at competitive prices is B&H Photo, which has an extensive selection of brands and types and sizes. Get filters at B&H Photo.

Zeiss info

The Zeiss UV filters were introduced in late 2011.

For colors as rich as in nature

Crystal clear: the UV filters featuring the T* anti-reflective coating from Carl Zeiss provide optimal protection for the front element of your lens. They also ensure absolute brilliance without altering the color rendition or exposure time.

• Quality — High-quality glass featuring Carl 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

Spectral transmission — Zeiss UV filters

This is what I want to see in a UV or clear filter: a sharp cut from near-UV to indigo, and transmission close to 100% out to 650nm.

However, note that the Zeiss UV filter cuts out long-wave UV and the very deepest indigo. This is probably by design. Compare to the B+W 010, which passes more indigo.
