Used Schneider 4x4" ND 0.6, Neutral Density Professional Glass Filter. #68040644

Take your photography and cinematography to the next level with the 4x4" Neutral Density ND 0.6 Professional Glass Filter from Schneider. Engineered to control exposure or depth of field under varying lighting conditions, these filters do not affect color or contrast, setting them apart from other brands. Schneider's Absorptive ND filters are a neutral gray, achieved with meticulous laboratory precision, ensuring the highest quality for your images.

Crafted from crystal-clear, water-white optical glass, Schneider filters are diamond cut, then ground and polished to achieve precise flatness and plane-parallelism. This exact parallel relationship between the front and back filter surfaces is verified by a laser interferometer, guaranteeing perfection in every piece.

Schneider filters undergo rigorous testing for consistent density with a densitometer and for proper light transmission with a spectrophotometer. This high level of consistency allows cinematographers to switch filters mid-shoot without any noticeable variation in color or effect. The unparalleled purity, color saturation, and repeatability of Schneider filters virtually eliminate the need for lab color timing correction, saving you time and effort.

Built to withstand the most demanding conditions on set or location, Schneider filters feature a specially formulated hard anti-reflective (AR) coating. This proprietary coating resists flaking, peeling, and scratching, while reducing light loss and flare to less than 1% per surface. This is a significant improvement compared to untreated glass, which has a light loss of 4% per surface.

Schneider's screw-on filters are designed with virtually jam-proof brass precision mounting rings. Unmounted Schneider laminated filters are protected against delamination and edge-chipping by Schneider's unique Edge Seal, which also reduces edge reflection and edge flare.

Contrary to the common perception that filters should not be used in front of long length lenses, Schneider filters are an exception. Poorly made glass or plastic-resin filters can degrade the image quality, but Schneider filters, thanks to their superior quality control, high-quality glass, and advanced grinding and polishing techniques, can be used confidently with even the longest lenses. Experience the Schneider difference and elevate your visual storytelling with the 4x4" Neutral Density ND 0.6 Professional Glass Filter.
