•Light rays which are reflected by any surface become polarised and polarising filters are used to select which light rays enter your camara lens. • They allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. • They also saturate colors and increase contrast.
•Polarizers come in two variations but have the same effect. Linear polarizers work with older camera meters; circular polarizers are designed for today's newer slpit-beam metering systems used in auto focus cameras; check your camera's manual.
The X-PRO Universal Ring was specifically conceived for the wide-angle zoom lens Nikkor 14-24mm, which has no filter thread and can't accept any threaded filter or filter-holder. Thanks to the new COKIN X499-N Universal ring, you can now use polarizing, ND or gradual filters just like with any other zoom lens. Furthermore, with large sized X-PRO filters, there is no problem with vignettingyour wide-angle landscape images with a DX sensor.*
*Vignetting under 18mm with a full frame sensor (FX).
The X-PRO Universal ring does not thread onto the lens, it fits on the lens hood. It is attached with the 8 screws provided, which guarantee total steadiness. Once attached, you will enjoy the simplicity of the COKIN creative system: slide the filter-holder in the adapter ring and use all the filters needed to create beautiful images.
With COKIN polarizing filters, truly re-enforce your landscapes. It's a pity to use such a great lens without any filters. Shooting with a top notch lens and no filter is like eating a great meal without any spice, there is a sense of incompletion. Make sure the best light is taken advantage of without making poor exposures or loosing important details in shadows and highlights. Thanks to the wide range ofND and ND grad filters, a balanced exposure can be achieved quickly and easily with out spending hours in post production. Take evenmore control; COKIN polarizers not only control balance but also create dramatic effects by reducing or enhancing reflections in water and glass surfaces. For even more creative control try COKIN's range of gradual colored, center spot and special effect filters.
