The Z4101S adapter ring allows you to use the Cokin NX-Series filter-holder with your Sony FE 14mm F1.8 GM lens. The ring is precision machined in anodized aluminum and its design is optimized to remove a maximum of vignetting and to get rid of a cumbersome filter-holder system of 150mm type. You can use up to 3 filters together and enhance your precious shoots made with the Sony FE 14mm F1.8 GM lens.
When the NX-Series system is mounted on the Sony lens by means of the adapter ring Z4101S, there is no vignetting in the corners of the image with one or 2 filters in their frame when the polarizing filter is not used (filter-holder used horizontally or vertically at 90°). If you use the polarizing filter alone or with one or 2 filters in their frame, there is a slight vignetting in the corners. We do not recommend using the filter-holder tilted at 45° or at a similar angle, as it will create a vignetting at least in 2 corners whatever the filters used. Concerning the management of your photographic files, we recommend that you shoot in raw files and process them in a software like Lightroom Classic, by activating the lens correction profile of the Sony FE 14mm F1.8 GM lens.
