Used Schneider 4x4" LowCon-2000 # 2, Contrast Control Professional Glass Filter

Are you a professional photographer or cinematographer seeking high-quality, durable, and effective tools for your craft The 4x4" LowCon-2000 #2 Contrast Control Professional Glass Filter by Schneider is a versatile solution designed to enhance your work. This filter is renowned for its ability to lower contrast and distribute light into shadow areas, thereby improving overall image quality.

Crafted from crystal-clear, water-white optical glass, each Schneider filter is diamond cut, then ground and polished to achieve precise flatness and plane-parallelism. This meticulous process ensures an exact parallel relationship between the front and back filter surfaces. To guarantee perfection, each filter's flatness and parallelism are verified by a laser interferometer.

Consistency is key in professional photography, and Schneider filters deliver. Each filter is checked with a densitometer for consistent density and tested with a spectrophotometer for optimal light transmission. This ultra-high consistency allows for seamless filter swapping 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.

Schneider filters are designed to withstand the most rigorous demands on set or location. Many feature Schneider's specially formulated hard anti-reflective (AR) coating, which resists 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 screw-on filters feature 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 common perception, Schneider filters can be used in front of even the longest lenses without degrading image quality. This is due to Schneider's commitment to quality control, high-quality glass, and superior glass grinding and polishing techniques. Choose the 4x4" LowCon-2000 #2 Contrast Control Professional Glass Filter by Schneider for a versatile, effective, and professional solution to your photography needs.
