Round 77mm yellow glass camera filter with multi-coated finish

HOYA Filter

HOYA Filter Yellow K2 Multi Coated Glass 77mm camera filter

SKU CH-WKKV-Y7DXT

A 77mm yellow K2 filter that adds mild contrast to daylight scenes and balances flash portraits

  • Natural tonal range for black-and-white images
  • Mild contrast boost for sky, foliage and architecture
  • Multi-coated glass cuts flare and glare
  • Offsets cool tones in flash portraits
  • 77mm thread fits matching lenses

Purpose and fit

This 77mm yellow K2 filter is made for photographers who shoot black-and-white film or digital and want a subtle lift in contrast across skies, foliage and architecture. It also serves portrait shooters looking to warm flash output for more natural skin tones. It is not for buyers who need strong red or orange contrast effects, or who require a neutral-density filter for long exposures.

Thermals noise power

As a passive glass filter it generates no heat, draws no power and adds no audible noise to the shooting process. The multi-coated surface reduces flare and ghosting without affecting the camera’s metering or autofocus performance.

Build integration

The filter threads onto any 77mm lens front and stacks with other 77mm filters when needed. Its slim frame minimises vignetting on wide-angle lenses, leaving the lens hood and cap fully usable. No adapter rings or step-up rings are required if the lens already matches the 77mm thread.

Highlights

  • Natural tonal range for black-and-white images
  • Mild contrast boost for sky, foliage and architecture
  • Multi-coated glass cuts flare and glare
  • Offsets cool tones in flash portraits

Questions about this item

How do I fit the 77mm Yellow K2 filter onto my lens without cross-threading?

Align the filter threads with the lens front thread, turn clockwise until resistance is felt, then give a light quarter-turn to seat the multi-coated glass evenly.

What upkeep will the multi-coated glass need over time?

Clean with a blower, then a microfibre cloth and optical fluid; the coating resists flare but can wear if abrasive materials are used.

Which shooting condition hits the filter’s contrast limit first in bright daylight?

Strong backlit scenes with hazy skies push the mild yellow absorption to its contrast ceiling before other conditions do.
