Red 25 contrast filter for black-and-white

The HOYA 55mm Red 25 glass filter deepens blues and blue-greens while enhancing red and orange tones in monochrome images. It creates dramatic contrast in skies, water and architectural scenes and can simulate moonlight when underexposed. The 55mm thread fits a wide range of lens diameters. Black-and-white film and digital shooters seeking strong tonal separation will find it essential.

Single-coated glass reduces reflections in normal

High-quality optical glass with a single-layer coating cuts surface reflections to preserve clarity and contrast during everyday shooting. The thin filter ring adds minimal weight to the front of the lens and does not extend far enough to cause vignetting on most wide-angle designs. No power or electronics are involved, so there is no heat or noise to consider.

Consistent performance under sustained outdoor use

The filter maintains its contrast effect throughout long landscape sessions, whether piercing haze with infrared film or darkening blue skies in bright daylight. Glass construction resists scratches better than resin alternatives when cleaned repeatedly in the field. The coating remains stable across temperature swings typical of all-day shooting.

Questions about this item

How do I attach the 55mm Red 25 filter and what step do people often miss?

Screw the filter onto the 55mm front thread of your lens until snug; the step many miss is removing any existing UV or protective filter first to avoid vignetting and ghosting.

What maintenance will the Red 25 glass filter need over time?

Clean the coated glass with a blower, then a microfibre cloth and lens fluid when smudges appear; the single coating is durable but can wear if scrubbed with grit, so always blow dust off before wiping.

What limit appears first when using the Red 25 filter in bright, sustained shooting?

The filter factor of 25 (about three stops) forces longer exposures or wider apertures, so motion blur or shallow depth of field becomes the practical limit before any optical degradation occurs.
