The#jaworskyj 100x100mm filter system is suitable for using the polarizing filter on the camera. It includes both ND filters and graduated filters , a filter holder with up to three compartments for several filters and various connection rings , all of which are available separately.
The particular advantage of this system is its universal use. A filter holder and the appropriate adapter ring are sufficient to use filters with several lenses (and therefore several cameras).
Simply screw the appropriate adapter ring onto the lens and attach the filter holder to it. This means that the polarizing filter can be easily used with lenses with a focal length of around 16mm or more on a full-format camera (APS-C from around 10mm).
The advantage of the rectangular polarizing filter is that you don't have to rotate it to achieve the optimal effect. Even if you switch from landscape to portrait format, you don't have to rotate the filter itself, you can simply rotate the entire filter holder.
