Schneider 4x4" Storm Blue Solid Color # 2, Professional Glass Filter

Explore the transformative power of the 4x4" Storm Blue Solid Color #2 Professional Glass Filter. Designed to add a grey-green hue to ocean and sky scenes, this filter creates a captivating stormy effect that enhances your photography and cinematography projects.

Crafted from crystal-clear, water-white optical glass, each Schneider filter is diamond cut, then meticulously 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, ensuring perfection in every piece.

Consistency is key in the world of professional photography and cinematography. Schneider filters are checked with a densitometer for consistent density and tested with a spectrophotometer for proper light transmission. This ultra-high consistency allows for seamless filter swaps 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.

Built to withstand the most rigorous demands 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 over untreated glass, which has a light loss of 4% per surface.

Schneider screw-on filters are equipped 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 designed to overcome this challenge. Poorly made glass or plastic-resin filters can degrade the image quality, but Schneider filters, with their superior quality control, high-quality glass, and advanced grinding and polishing techniques, can be used confidently in front of even the longest lens.
