These filters are made from high-quality optical glass and feature a brass mount that can withstand temperature fluctuations. This ensures a long lifespan and prevents the filter from getting stuck on your lens.

The Master series has a thinner mount specifically designed to prevent vignetting with wide-angle lenses. The Basic series has a standard mount and offers the same optical quality for lenses with a normal focal length.

MRC stands for Multi-Resistant Coating and provides better light transmission and fewer unwanted reflections. Additionally, this hard layer makes the filter water-repellent and scratch-resistant, making it easier to keep the glass clean.

You look for the diameter of your lens, which is often indicated on the front or side with a diameter symbol. The filter must have the exact same millimetre size to fit on the thread.
