Urth Magnetic Filter Kit

The kit includes a magnetic adapter ring that screws onto your lens filter thread. Once that is in place, the filters snap onto the front magnetically, allowing you to swap between the UV, CPL, or ND filters instantly without having to screw and unscrew them.

No, the filters are designed with an ultra-slim rim specifically to prevent vignetting. You should be able to use them on most wide-angle lenses without seeing dark corners in your frame.

Yes, the magnetic design is built for stacking. You can easily layer the filters, such as combining the CPL with an ND filter, to manage both reflections and light reduction simultaneously.

The nano-coating serves two main purposes: it makes the glass significantly easier to clean by repelling water, oil, and dirt, and it reduces internal reflections to maintain image sharpness and contrast.

Because these filters use a magnetic mounting system, standard clip-on lens caps may not fit directly onto the filter itself. You will generally need to remove the magnetic filter or use a compatible magnetic lens cap.

The ND8 provides a moderate light reduction (3 stops), which is ideal for slightly slowing your shutter speed in bright daylight. The ND1000 provides a heavy reduction (10 stops), which is necessary for long-exposure photography, such as smoothing out moving water or clouds.
