Overview

The Hoya 77mm Softener (B) is a special-effect screw-in filter designed to introduce a controlled soft-focus quality directly at the point of capture. Its optical surface is covered with randomly arranged micro-lenslets shaped like tiny water droplets, which scatter incoming light to produce smooth gradations and a gentle glow around highlights — all while preserving a recognizably sharp central image. The result is a dreamy, romantic look that is especially flattering for portrait photography and scenes featuring point light sources such as candles or streetlights.

Unlike post-processing softening, the Hoya Softener (B) interacts with actual light entering the lens, creating halation and bloom characteristics that are difficult to duplicate digitally. The "(B)" designation indicates a moderate-to-strong diffusion level within Hoya's softener lineup. The filter threads onto any 77mm lens and adds negligible weight, making it easy to carry as part of a filter kit. Because the effect is baked into every frame, photographers who want flexibility may wish to bracket shots with and without the filter to preserve options during editing.

Pros & Cons

👍 Pros

  • Produces a soft-focus effect optically at capture time, giving a look that is difficult to replicate identically in post-processing.
  • Micro-lenslet construction maintains a sharp core image while adding smooth gradation around highlights and edges.
  • Standard 77mm screw-in design attaches quickly without adapters or special holders.
  • Lightweight acrylic-based construction adds virtually no weight or bulk to the lens.

👎 Cons

  • The diffusion strength is fixed at a single level with no way to dial it back without removing the filter.
  • The soft-focus effect applies to the entire frame and cannot be selectively masked to specific areas.
  • At 77mm this filter fits only one thread size, requiring step-up rings for use on smaller-diameter lenses.
  • The acrylic optical element may be more prone to scratching than multi-coated glass filters.

Frequently Asked Questions

The Softener (B) produces a stronger diffusion effect than the (A) version, scattering more light for a more pronounced soft-focus look while still retaining a sharp central subject.
The Softener (B) causes minimal light loss. It redistributes light rather than blocking it, so exposure compensation is generally not needed.
The effect strength is fixed at the (B) level. To vary intensity you would need to switch to the lighter (A) version or remove the filter entirely.
This is a 77mm threaded filter. It screws directly onto any lens with a 77mm front filter thread. Check your lens cap or front ring for the diameter marking.
