Simmod MRC Circular Polarizer Filter (82mm)

Polarizing filters are designed to control reflected light before it reaches the image sensor.
This allows changes to glare, reflections, saturation, and atmospheric contrast directly in-camera.

The Simmod MRC Circular Polarizer Filter (82mm) is a screw-in optical filter designed to reduce reflections from non-metallic surfaces while increasing color saturation and contrast in both photography and cinematography workflows.

Filter Format

• Rear thread size: 82mm
• Front thread size:82mm
• Circular rotating polarizer design

The front threading allows additional filters or accessories to be mounted when required.

Optical Function

The filter is designed to:

• Reduce reflections from:
  • Glass
  • Water
  • Painted surfaces
  • Foliage
• Minimize atmospheric haze
• Increase perceived color saturation
• Improve sky separation and cloud contrast
• Reduce glare from reflective non-metallic surfaces

The polarizing effect changes depending on:

• Filter rotation angle
• Position of the sun relative to the lens
• Scene lighting conditions

Maximum polarization effect typically occurs when shooting approximately 90 degrees relative to the sun.

Circular Polarizer Design

The filter utilizes a circular polarizing structure compatible with:

• Autofocus systems
• Digital metering systems
• Modern mirrorless and DSLR cameras

Unlike linear polarizers, circular polarizers are designed to maintain compatibility with electronic focusing and exposure systems.

Optical Construction

• Constructed from German Schott optical glass
• Multi-Resistant Coating (MRC) applied to optical surfaces
• Multi-coated design intended to:
  • Reduce reflections
  • Minimize ghosting
  • Improve light transmission
  • Maintain optical clarity

The coating system also provides resistance to:

• Oil
• Dust
• Moisture
• Surface contamination

Mechanical Construction

• Precision-machined brass filter ring
• Slim-profile frame design
• Rotating outer ring for polarization adjustment
• Matte black internal finish to reduce reflections

The brass frame is designed to:

• Reduce thread binding
• Maintain dimensional stability
• Improve durability during repeated installation and removal

Mechanical Performance

• Smooth rotational adjustment for polarization control
• Stable threaded mounting interface
• Slim profile designed to reduce vignetting on wider focal lengths

The filter is compatible with:

• Photography lenses
• Cine lenses using threaded filter interfaces
• Matte box workflows using threaded adapters

The filter produces:

• Increased saturation of skies and foliage
• Reduced reflective glare
• Improved contrast in atmospheric conditions
• Cleaner rendering through glass and reflective surfaces

The visual effect strength varies depending on:

• Lighting direction
• Filter rotation
• Lens focal length
• Surface reflectivity

System Behavior

• Passive optical filter
• No electronic components
• Does not alter internal lens mechanics or calibration

Compatible with:

• Spherical lenses
• Anamorphic lenses
• Digital cinema cameras
• DSLR and mirrorless systems

Included Components

• 82mm Circular Polarizer Filter
• Protective felt or leather storage case

Notes

• Requires compatible 82mm front filter threads or step rings
• Polarization intensity changes as the filter rotates
• Uneven sky polarization may occur on ultra-wide-angle lenses due to broad field-of-view coverage
