B + W 40.5mm Soft Pro Schott Glass Filter

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.

Filter Coating
Uncoated Glass
Uncoated glass is usually found with special effects filters and acrylic filters, where coating is either an impossibility or would work against the effect the filter is trying to attain.

Mount
This filter uses standard B+W F-Pro filter mount, which has a front accessory thread and is made of brass. Compared to the earlier standard mount introduced in 2001, the F-Pro mount has become thinner. Now it can be used with wide angle lenses, including most 24mm focal lengths on a full frame body, without vignetting. Another advantage of the F-Pro mount is its modified retaining ring, which is no longer threaded in from the front, but holds the filter glass in place from the back. When removing a filter or lens hood that has been screwed on too tight to the filter, the retaining ring is not at risk of loosening.
