SKU CH-EP82-1TCZ7

A 138 mm kit combining a circular polariser, an ND 5.6 filter and a variable ND up to 2.7 stops, made from German optical glass

  • Professional-grade filter kit built with high-grade German optical glass
  • 138 mm circular polarizer boosts contrast and saturation
  • Variable ND delivers up to 2.7 stops of light control
  • Flip the ND filter to shift color temperature for natural results
  • ND 4x5.6 filter enables precise exposure management in bright conditions

Versatile 138mm Filter Kit

This professional-grade kit combines a circular polarizer and an ND 4x5.6 filter for versatile photography. It fits 138mm round filter trays and uses high-grade German optical glass for durability. The polarizer reduces glare while enhancing contrast and saturation in skies and water.

Variable ND and Colour Temperature

Pairing the polarizer with the ND filter creates a variable ND providing up to 2.7 ND of adjustment. This controls light exposure without altering scene hue for motion blur and depth of field. Flipping the ND filter adjusts colour temperature for natural-looking results.

German Optical Glass Construction

Crafted from high-grade German optical glass, the filters promise durability and high-quality performance. The 138mm circular polarizer fits seamlessly into compatible round filter trays. The kit design allows quick transitions between polarisation, variable ND, and colour temperature functions.

Questions about this item

How often will the German optical glass on the 138mm Circular Polarizer need replacement?

The high-grade German optical glass is built for durability and does not require scheduled replacement; clean with a microfibre cloth and lens fluid only when smudges appear.

What is the maximum light-reduction limit of the variable ND function?

The variable ND tops out at 2.7 ND, so you cannot dial in more density than that without adding another filter.

How much heat does the 138mm filter kit add to the lens barrel during all-day video shoots?

The glass filters are passive optical elements; they generate no heat themselves and only transmit the ambient temperature reaching the front of the lens.
