B+W 62mm Soft Image filter (655 77366)

Subject contours “flow” markedly softer with the Soft Image attachment on the lens than they do with the B+W Soft Pro. Prominent halos form around light sources and reflections, and bright parts of the subject acquire a noticeable veil of light. This effect is maintained even when the lens is stopped down. It is recommended for portraits and for backlit situations (however, it may be too soft for some landscapes).
