Cokin's sheet filters are very easy to use. An adapter ring, a filter holder and a filter are required for its use. Adapter ring: We place an adapter ring on the lens (the size corresponding to the filter size of the lens, which is indicated on the optics and on the protective cap). The A-size holder is compatible with lenses with a filter thread between 36-62mm, the width of the filter is 67mm. The P size holder is compatible with lenses with a filter thread between 48-82mm, the width of the filter is 84mm. The Z size holder is compatible with lenses with a filter thread between 52-96mm, the width of the filter is 100mm. The X size mount is compatible with lenses with a filter thread between 62-112mm, the width of the filter is 130mm. Filter holder: The filter holder must be pulled onto the intermediate ring from bottom to top until it clicks. There are two types of these, the normal and the wide-angle lens mount. This includes the filters we bought, for a more beautiful, perfect image effect. In the normal one, you can place 3 sheet filters at the same time, while in the case of the wide-angle filter holder, only one is possible, because otherwise it would hang in the picture, and in addition to the sheet filters, you can also insert a circular Cokin filter in the part closest to the lens (e.g.: polar filter). In the case of a camera with a full frame sensor, the wide-angle mount should/should be used for a lens below 24 mm. Filter: The sheet filter can simply be pushed into one of the filter holder slots. You can choose a full or transitional filter, these can be combined in any way. That's all, we can go take photos!
