The effect of this B+W soft focus attachment is created by fine lenticular protrusions that have been applied to a high-grade plano-parallel plate of glass in a random pattern. The light passing through between these protrusions creates a sharp core image for accurate focusing and great detail. This is an important feature for photographers using AF reflex cameras. The light diverted from its regular direction by the mini-lenses, coats the image with a diffuse halo of light for a delightful softness. This soft focus attachment is as ideal for portraits, especially with highlights in blond hair. You can also use this attachment to create dreamy landscapes.
