Next, Cokin designers opted to eliminate the traditional filter slots that waste space between filters for micro ball-bearings on the inside of the holder. We used a dime to show just how thin this new design is! Shop the NX System This means the polarizer does not add extra bulk to the system when it is used. Polarization is controlled by spinning a wheel on the outside of the holder. When you snap the polarizer into the frame, it sits flush. Some square filter holder systems include threads on the outside of the holder, not on the inside. CANON RF 15-35mm F2.8L : slight vignetting only at 15mm with filters and the filter-holder rotated by 45°, which disappears levelįirst, The NX holder cleverly houses the dedicated all-glass Circular Polarizer within the skeletal frame.NIKON Z 14-30mm F4 : slight vignetting only at 14mm with filters and the filter-holder rotated by 45°, which disappears level.FUJIFILM XF 10-24mm F4R OIS : no vignetting even at 10mm.SONY FE 16-35mm F2.8 GM : no vignetting even at 16mm.CANON EF 16-35mm F2.8L III USM : no vignetting even at 16mm.The NX system was tested on the following lenses with the included data: On super-wides this means the camera will see the corners of the holders and filters placed in front of it.Ĭokin has managed to design several components into a new, ultra thin design that works with super-wide-angle lenses up to 16mm wide and hold a circular polarizer and (2) 100mm wide square or rectangular filters without vignetting. The wider the lens, the wider the field-of-view. Vignetting, or darkening of the corners, is caused when you start adding holders and filters to the front of the lens. For a long time, landscape photographers have had a great frustration when shooting on super-wide-angle lenses: vignetting.
