Heliopan B/W Filter 1075 | red bright (25) | Ø 77 x 0,75 mm | SH-PMC coated
The ideal filter for contrast increase, as it swallows green and blue completely and emphasizes red. Clouds are highlighted vigorously
- Red light filter (25)
- Slimline brass filter entry
- Remuneration (7-fold)
- Extension factor is about 8x
- Best optical SCHOTT glass
- Heliopan Filter Type 1075
- Internat. Filter No. 25
The ideal filter for contrast increase, as it swallows green and blue completely and emphasizes red. Clouds are highlighted vigorously - to the thunderstorm. For aerial photography, the haze is better penetrated, as well as moonlight effects can be achieved (suitable for infrared).
The extension factor is about 8x. For TTL measurement, adjust exposure compensation +1
Made in Germany
The high-quality Heliopan Neutral Density Filter are made in Munich, offer first-class optical properties and a high-quality manufacturing quality. For the production of Heliopan ND Filters, SCHOTT glasses are used. The SCHOTT Filter glasses ensure perfect sharpness and thanks to spectrally balanced damping neutral color reproduction. The Filter glass is fully sanded and smoothly polished.
Heliopan SLIM Filter
The Filter fittings are made precisely from brass. Brass is dimensionally stable and robust. The brass capture causes no quality-reducing mechanical stresses in the Filter glass because of its very low thermal expansion even with strong temperature fluctuations. Further, the risk of jamming in the Filter thread of the lens is minimized. The black coating of the brass capture prevents possible influences by reflections on the socket. Thanks to a Filter height of 4 mm, the Filter can also be used on wide-angle lenses without causing vignets. For a camera with full-former sensor, the smallest possible focal length is approx. 24 mm, with a camera with APS-C sensor, it is about 18 mm. All Heliopan Slim brass captures have a front thread in the same size of the screw-in detection (of the Filter diameter), so that another Filter, a lens hood or other accessories can be screwed. By using state-of-the-art high-tech machines, both in metalworking as well as in the optics, the highest quality is guaranteed
Heliopan SH-PMC Multicoating
The reflection on glass / air surfaces is making a major cause of loss of contrast in objectives, the most demanding in the extreme Photography impossible. Therefore, lens manufacturers operate an enormous effort for the remuneration of their lenses. This quality chain should not break it by using a filter with inferior compensation. With new proprietary systems and technologies Heliopan filters are provided with a much improved remuneration. The existing on each side of each of seven layers broadband coating reduces not only the reflectance in the visible light range to near zero percent, it is also water- and dirt-repellent. This makes it considerably more resistant to injury and easier to clean than previous MC filter or a front lens.
