This DHG Super Circular PL.D creates circularly polarized light. It can be used to darken bright skies and hence the contrast between the clouds and the sky will be increased. It can also reduce atmospheric haze and reflected sunlight. In color photographs, the overall color saturation can be increased. Unintended vignetting is the most common defect when operating a DSLR with super-wide-angle lens. To entirely eliminate this problem, you need a high quality filter with excellent multi-layer coating and extra-thin frame. That is why this Japan made Marumi DHG Super Circular PL.D stands out from its peer. Made of the latest developed anti-reflection super-transparent multi-coating lens, this filter is specifically designed for CCD in the DSLR. Thanks to the ion-exchange precipitation coating technology, it not only filters undesirable light but also corrects any distortion coming from electronic conversion Quality tells everything. The wide-type super-thin frame is sealed with carbon fibre anti-reflection substance. The ultra low reflection coating helps minimize flare-ghost. The 'Black-ink' process on the lent's outer helps minimize inner reflection while the satin-like smooth frame minimizes extra reflection. There is also a layer of special coating that prevents oil and water spread, as well as finger print marking; The screw on the front side connects lens and lens cap with corresponding filter size.
