Heliopan B/W Filter 1029 | red (29) | coated
The ideal filter for contrast increase, for dramatic cloud shots. It helps with reproductions of yellowed documents and is used for tone separation in case of property and color statements.
- Red dark filter (29)
- Slimline brass filter entry
- Remuneration (4-fold)
- Extension factor is about 8 - 12 x
- Best optical SCHOTT glass
- Heliopan Filter Type 1029
- Internat. Filter No. 29
The ideal filter for contrast increase, as it swallows green and blue completely and red extremely emphasized. Clouds are highlighted vigorously - to the thunderstorm. Likewise, moonlight effects can be achieved (suitable for infrared).
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 coating
Reflection on glass / air surfaces is one of the main causes of contrast losses in lenses impossible in extreme detaching photography. Therefore, objective manufacturers operate a tremendous effort in the coating of their lenses. You should not break this quality chain by using a Filter without coating. The company's own plants and technologies provide the Heliopan Filters with a 4-fold coating. The mirror reflection not only reduces the reflection in the visible area of light, it is also water and dirt repellent. This makes it very robust against damage and easier to clean
