NiSi Explorer Filters vs NiSi Optical Glass Filters

Our Explorer filters are twice the strength of our optical glass filters. They're made from B270 tempered glass compared to lens-grade optical glass found in our optical glass filters. Both filters feature the same NiSi Nano Coating. So why are Explorer filters less expensive? B270 glass is a less expensive raw material and we have passed on these savings. Any disadvantages? B270 has slightly lower transmittance and a slight loss in sharpness. Our Explorer filters perform so well the difference is virtually undetectable. Since the Explorer series are much less prone to accidental breakage, they’re perfect for active photographers.

Description

The NiSi Explorer Collection 150x170mm Nano IR Reverse Graduated Neutral Density Filter – GND4 (0.6) – 2 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 a typical glass filter.  The Explorer series are much less prone to accidental breakage and perfect for active photographers.

The NiSi Explorer Collection 150x170mm Nano IR Reverse Graduated Neutral Density Filter – GND4 (0.6) – 2 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. Reverse edged GNDs are similar to hard-edged GNDs except that the darkest part of the filter is at the transition point. These filters have a specific use for shooting at the light source where the light is harshest at the horizon and tapers off toward the sky.  This type of filter is most appropriate for scenes that have a sudden transition from the foreground to the sky with the brightest part of the scene near the horizon. Most commonly, this would include landscapes with no elements protruding above the horizon such as a seascape looking toward the open ocean. They can be used shooting into the direct light where a sharp transition is needed.

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.

This 150x170mm filter is compatible with the NiSi 150mm filter system.
