  • 43 mm thread fits wide-angle lenses down to 24 mm focal length
  • Brass F-Pro mount thinner than 2001 design prevents vignetting on wide angles
  • Uncoated glass preserves intended softening effect without reflection interference
  • Ideal for portrait highlights and ethereal landscape mood

43mm Soft Pro diffusion filter

This 43mm Soft Pro filter adds a subtle diffusion effect that softens highlights while preserving a sharp core image. It is designed for photographers who want a dreamy look in portraits or landscapes without losing focus accuracy. The effect comes from fine lenticular protrusions applied in a random pattern on Schott glass.

Consistent softening under sustained use

The diffusion pattern is physically etched into the glass, so the effect remains identical shot after shot regardless of how long you shoot. There is no coating that can wear off or degrade the softening behaviour over time. The uncoated surface ensures the intended halo around highlights is maintained throughout the filter's life.

Brass F-Pro mount with 43mm front thread

The filter uses a thin brass F-Pro mount introduced after 2001 that fits wide-angle lenses down to 24mm focal length. Its 43mm front thread accepts standard 43mm lens caps and allows stacking if needed. Brass construction resists binding and corrosion during frequent attachment and removal.

Questions about this item

Does the 43mm Soft Pro Filter generate any heat or noise during extended shooting sessions?

No, this passive glass filter has no electronics, so it produces no heat and makes no sound regardless of how long you use it.

What lens thread size must my lens already have for this filter to attach directly?

Your lens needs a 43mm front filter thread to screw the filter on without an adapter ring.

Will the F-Pro brass mount introduced after 2001 vignette on my older 24mm wide-angle lens?

The thinner F-Pro mount is designed to work with most 24mm lenses, reducing the chance of vignetting on older wide-angle glass.
