<\/a>Transmission chart \u00a9STC<\/p>\nSTC screw in filters are supplied in a tough plastic case with foam inside, also supplied is a small microfibre cleaning cloth.
\nAll three filters are made with German supplied Schott glass, ultra thin, ultra slim, cut UV light and are antistatic, oil and water resistant.<\/p>\n
For our test we used a Nikon D800, tripod mounted and equipped with a 35mm f2 lens set to f11 and used in aperture priority, white balance set to daylight and ISO 100. The shutter was triggered by wireless remote.<\/p>\n Once again our main test target was Eastbourne Pier, this is an ideal subject due to the struts giving a good indication of sharpness and fringing.<\/p>\n Testing<\/strong><\/p>\n In the pier and sky test each filter was rotated to produce maximum increase in blue sky.<\/p>\n With the breakwater and water test, each filter was rotated to maximum reflection reduction.<\/p>\n Results<\/strong><\/p>\n As we have come to expect from STC rotation of the filter ring is very smooth and all the filters produced sharp even edge to edge images, with a neutral colour balance.<\/p>\n The hybrid polarising filter gave a good level of sky saturation, both the SHV and the CPL-M ND16 increased the blue level even more, the ND16 version did however also give a slightly darker and fractionally yellow overall image, but this can easily be compensated for either in camera or at the post production stage.<\/p>\n The reflection test again had the hybrid filter giving a slightly less reduction in reflection compared with the SHV and the CPL-M ND16 filters as was expected.<\/p>\n Conclusion<\/strong><\/p>\n All three polarising filter gave excellent results. Which one to buy? Hard to give a definitive answer. The hybrid filter is great if you want to fit a polarising filter for use under all lighting conditions due to light transmission only being reduced by half a stop. Both the SHV and the CPL-M ND16 work very well in bright light, with the ND16 version coming into its own if you like to shoot images with a wide aperture under very bright light, or wish to use slower shutter speeds, to create blur for instance.
