Schneider HD Classic Soft filters were designed in response to requests for a high-quality softening filter to complement the new high-resolution 1/2", 1/3" and 1/4" chip cameras. Based on our renowned Classic Soft™ filters for cine cameras, HD Classic Softs deliver the same subtle, effective softening performance. HD Classic Softs impart a closely confined, very subtle glow to highlights. If large amounts of overexposure exist in a scene-like a “blown” window – they produce a stylish glow that keeps the scene’s contrast under control, while adding a romantic look.
This effect also blends small wrinkles and blemishes, while maintaining an overall sharp focus that conceals the fact that a softening filter has been used. What’s more, these filters are designed to allow shooting in all HD formats, without fear of artifacts.
This filter is available in strengths of 1/16, 1/8, 1/4, 1/2, and 1. These strengths achieve a very light to moderate diffusion.
When used on a full frame sensor, each HD Classic Soft strength is engineered to be one grade lighter than its Classic Soft counter part.
For example, an HD Classic Soft 1/2 will behave the same as a Classic Soft 1/4 on a full frame camera.
When used on smaller sensor cameras, 2/3" and smaller, the HD Classic Soft strengths match that of a full frame camera with a Classic Soft being used. For example, an HD Classic Soft 1/2 on a 2/3" camera will give a similar effect to an Classic Soft 1/2 on a full frame camera.
Each Schneider HD Classic Soft filter contains a carefully calculated amount of precisely positioned Micro-Lenslets™.
These provide a controlled soft image that is overlaid on a sharp, in-focus image, creating In-focus Diffusion™.

Schneider Classic Soft® filters are manufactured using optical glass that is diamond cut, precision ground and polished to ensure uniformity and consistency.
Sandwiched between two pieces of this optical glass (A) are hundreds of precision Micro-Lenslets (B).
During use, image light (C) that passes through each Micro-Lenslet is only slightly refracted (D), while light (E) passing between Micro-Lenslets is unaffected.
Classic Soft filters are tested with a laser interferometer to ensure exact flatness and the parallel relationship between both sides.
