NiSi - 100x150mm Explorer Nano IR Reverse Graduated Neutral Density (8) 0.9 Filter, 3 Stop

Because capturing the perfect shot requires precision and quality, the SIRUI GND Filter is a must-have for any serious photographer. This 2mm thick filter is compatible with both SIRUI and other 100mm filter holders, making it a versatile addition to your photography equipment. The SIRUI Filter Holder (NDH-001, Spec:100mm) is designed to securely attach SIRUI GND Filters onto full-frame camera lenses as wide as 16mm and filter diameters up to 82mm. This ensures a secure fit and optimal performance, even in challenging shooting conditions.Crafted from precision ground and polished German manufactured Schott Plate Glass B270, this filter guarantees the highest resolution and optical flatness. This premium material ensures that every shot you take is of the highest quality, with no compromise on clarity or detail.The SIRUI GND Filter also features an exclusive nano lens coating process. This innovative technique allows many ultra-thin layers of coating to be placed on each lens surface, ensuring perfectly linear, uniform reduction of light from edge-to-edge. This results in maximum light transmission, reduced reflections, and precise color rendition, enhancing the overall quality of your images.For added durability and ease of maintenance, this filter also comes with a Protection Coating. This coating is waterproof, oil-resistant, scratch-resistant, anti-reflective, and anti-static, making it easy to clean and providing superior lens protection.Finally, the SIRUI GND Filter is available in three variations: Soft Graduated, Hard Graduated, and Reverse Graduated. The Soft Graduated filter offers a subtle transition from light to dark, while the Hard Graduated filter provides a sharper line between the filtered and unfiltered area. The Reverse Graduated filter is graduated from the top and bottom, maximizing the effect in the middle of the exposure. This range of options allows you to choose the perfect filter for your specific shooting needs.

The NiSi Explorer Collection 100x150mm Nano IR Medium Graduated Neutral Density Filter - GND8 (0.9) - 3 Stop is part of our Explorer Series for made for adventure. The filters feature a special glass hardening process that makes them double the strength of typical glass filter. The Explorer series are much less prone to accidental breakage and perfect for active photographers. Double the Strength of Typical Glass Filter B270 Glass IR Layers for Accurate Color Low Reflection Nano Coating Compatible with 100mm Filter Holder systemsThe NiSi Explorer Collection 100x150mm Nano IR Medium Graduated Neutral Density Filter - GND8 (0.9) - 3 Stop is a rectangular filter that helps to darken specific areas of an image, such as bright skies while allowing for a normal, unaffected exposure in the other regions of the image. The filter is densest at the edge and tapers to clear by the middle, with a medium-edged line of transition between the dense and clear areas. A neutral density filter with a medium-edged line of transition is particularly useful for images that feature buildings, small mountains and other elements that protrude into high into the skyline. The transition zone of a medium is 40% smaller than a Soft GND and is wonderful for shooting at sunrise and sunset.NiSi GND filters do not affect the coloration of the image, offer a true to life color and are made from high-quality optical glass (not resin) with nano coating to prevent losing any single bit of detail. By using neutral density filter the camera is vulnerable to infrared light which will cast the unwanted red color to the photos when shooting at a small aperture. NiSi GND filters have an infrared protection coating layer to eliminate the infrared light through the lens to bring back the natural true to life color.The NiSi Explorer Collection is made from B270 tempered glass. It features the same Nano coating process as our optical glass filters. This filter is tempered and hardened making it much less prone to accidental damage but this does not mean it is unbreakable. After a long period of time, the hardening may decline. The NiSi 100mm filter system is great for cameras with lenses that have a standard filter thread from 49 mm to 95mm. Are They Shatterproof No. We introduced these filters for two reasons: To give you more options and to provide education in the market. B270 glass is a general purpose glass with good clarity and light transmission. It is used in many applications from high-quality touch screens and LCD covers to lens protection filters. B270 glass filters are a good quality glass filter which can be tempered or toughened, which has advantages. It is stronger than Optical quality glass and in most cases, it will survive drops from approx.. 1m onto concrete. However if dropped on a corner it may still chip and there is more risk of the lateral shock traveling through the glass and shattering it.The toughening process for this glass degrades over time. The time frame is impossible to measure and whilst it may never become an issue it is important for us to not make the claims of others. Whilst stronger to start with, over time the strength will degrade. This technology cannot be applied to high-quality optical glass, which is the reason they are not toughened. And for perspective, optical glass filters are very strong. Many of us have dropped a NiSi Optical Glass filter and it has survived with no damage. Is Image Quality Different In most cases, you may not see a difference. NiSi Optical quality filters give the highest image quality possible which is important considering the optical performance of today's lenses and the high resolution of modern sensors. For most photographic applications the image quality of B270 glass filters will be very good. For those demanding the highest possible quality image, sharpness and detail we would strongly suggest choosing our Optical glass filters. Why Are They Less Expensive B270 glass is a much more cost-effective glass to use that optical glass. For this reason, the cost of our Explorer filters is lower than our Optical quality glass filters. We decided to introduce these filters with a price that reflects the material used and not to over-inflate the claims or the price to the end user.

Where professional photography meets innovative technology, the 100x150mm Square Reverse Graduated ND8 3-Stop Lens Filter Plus+ is your go-to tool for capturing perfectly balanced sunsets and sunrises. This high-quality filter provides a fixed 3 f-stop light reduction across the center, allowing for a seamless blend of exposure levels in your images. Designed with a unique reverse graduated ND coating, this filter darkens the top half of your frame, starting from the middle and gradually fading towards the top. This feature is particularly effective when shooting in flat light conditions, such as during dawn or dusk, enabling you to capture more detail within the lowlights and highlights of your landscape and cityscape photography.The Plus+ range of our filters boasts a 20-layer nano-coating, ensuring a more consistent transmission curve for truer light reduction. This multi-coated design not only makes cleaning a breeze but also offers superior protection against water, oil, and scratches, enhancing the durability of your filter.Crafted with industry-leading German B270 SCHOTT optical glass, this versatile filter guarantees true color capture and smooth graduation for balanced exposure. The 20-layer nano-coating on this professional German glass ensures better light transmittance, protection, and ease of cleaning.The 3 f-stop darkening across half the filter allows for controlled exposures in graduated light with a defined horizon, such as mountains or the sea. This makes it an invaluable tool for photographers aiming to achieve a greater dynamic range, more even highlights and lowlights, and better sunrise and sunset captures.Our square filters are 2mm thick and are designed to fit most square filter holders, making them a versatile addition to your photography equipment.
