Cokin Diffusers have very little effect on the sharpness of the image. They merely diffuse highlights thus reducing contrast. As such, diffusers can be used to soften a landscape, or soften skin texture in a portrait to hide minor flaws. The 697 Diffuser Warm filter not only diffuses highlights but adds a slight warmth to the image.

This filter measures 66 x 72mm and fits the Cokin A series filter holder.
