Schneider 4x4" Neutral Density ND 0.9 Professional Glass Filter

Bring precision and professional quality to your photography with the 4x4" Neutral Density ND 0.9 Professional Glass Filter. This high-quality, durable filter from Schneider is designed to control exposure and depth of field under various lighting conditions without affecting color or contrast. Unlike other brands, Schneider's Absorptive ND filters are a neutral gray, achieved with laboratory precision, ensuring no color cast in your images.

Crafted from crystal-clear, water-white optical glass, Schneider filters are diamond cut, ground, and polished to a precise flatness and plane-parallelism. This exact parallel relationship between the front and back filter surfaces is verified by a laser interferometer, ensuring the highest level of precision.

The consistency of Schneider filters is unparalleled, with each one checked with a densitometer for consistent density and tested with a spectrophotometer for proper light transmission. This ultra-high consistency allows photographers and cinematographers to swap like filters mid-shoot with no discernible variation in color or effect. The unprecedented purity, color saturation, and repeatability of Schneider filters virtually eliminate the need for lab color timing correction.

Designed to withstand the most rigorous demands on set or location, Schneider filters feature a specially formulated hard anti-reflective (AR) coating to resist flaking, peeling, and scratching. This proprietary coating also reduces light loss and flare to less than 1% per surface, compared to untreated glass that has a light loss of 4% per surface.

Schneider's screw-on filters feature virtually jam-proof brass precision mounting rings, while 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, thanks to their superior quality control, high-quality glass, and precise grinding and polishing techniques, can be used in front of even the longest lenses without any degradation of the image.

Experience the Schneider difference with the 4x4" Neutral Density ND 0.9 Professional Glass Filter, and elevate your outdoor photography with balanced exposure, wider aperture, and a more pleasing bokeh effect.
