Zeiss T* CSC Filter 58mm

Zeiss T* CSC Filter 58mm – curved CSC interference cuts UV and IR without green/cyan color casts

The Zeiss T* CSC Filter 58mm uses a curved CSC interference design to reduce unwanted ultraviolet (UV) and infrared (IR) light while avoiding the typical green and cyan color casts that can appear, especially with wide-angle lenses. It delivers this benefit through a specific two-component optical construction.

Two-component optical construction

The filter consists of two optical glass elements: one with negative and one with positive refractive power. Between these elements, a dedicated filter layer sits. As a result, light-rays remain straight when passing through the filter, preserving the intended optical path.

What the curved CSC interference layer does

The curved CSC interference layer nearly completely cuts off UV and IR components. Therefore, you can reduce unwanted UV/IR influence on your images without experiencing the green and cyan color casts that sometimes occur with other filters. This effect is particularly important when using wide-angle lenses.

Key points

• Two-component design: one negative and one positive optical glass element.
• Intermediate filter layer that keeps light-rays straight.
• Curved CSC interference layer that cuts off UV and IR components almost completely.
• Designed to avoid green and cyan color casts, especially with wide-angle lenses.
• Filter thread size: 58mm (as indicated in the product name).

Use cases

Use this filter when you need to reduce UV and IR influence without introducing color shifts. In particular, opt for this filter when shooting with wide-angle lenses, where color casts are more likely to be noticeable.

FAQ

Question: Will this filter cause green or cyan color casts on wide-angle lenses?
Answer: No. The curved CSC interference design is specifically made to avoid the green and cyan color casts that can occur with some filters, which is particularly beneficial when using wide-angle lenses.

Question: What does the two-component construction mean and why does it matter?
Answer: The filter uses one negative and one positive optical glass element with a filter layer between them. This arrangement keeps light-rays straight as they pass through, maintaining the intended optical path and helping to preserve image color rendering.

Question: How effective is the filter at removing UV and IR light?
Answer: The curved CSC interference layer cuts off UV and IR components almost completely, reducing their impact on your images while avoiding the color shifts associated with some other filters.
