The Haida 150mm filter system involves the use of a dedicated 150mm filter holder, which connects to the lens via a compatible adapter ring.
The 150mm system is designed for use with ultra wide-angle lenses where a traditional threaded filter can not be attached due to the rounded front element of the lens.
The 150mm filter system can be preferred for easy compatibility with a wide range of lens sizes, as well as the flexibility offered by mixing and matching different filter types (square 150x150mm, rectangular 150x170mm, and dedicated circular filters).
For example, the 150x170mm Graduated ND filter can be adjusted by moving the filter up or down within the holder to change where the graduation line falls in the image, which is not possible with a traditional circular filter.
