This filter delivers sharp pictures which are softly overlaid with unsharpness. Small mini-lenslets are distributed randomly on a precisely plano-parallel glass disc. They scatter the light and overlay the sharp core image with hazy, diffuse halos. This opens up deep shadows, while highlights themselves are hardly blurred, but instead form a shimmering aura in the darker surroundings. In addition to portrait photography, soft focus attachments are used for great effects in landscape images. They reduce contrast and the light fringes in the backlight are softened. The photos take on a gentle, romantic character.
