A B+W 43mm Soft Pro Filter is a high-quality photographic accessory designed to enhance your images with a soft, dreamy effect. This effect is achieved through the use of fine lenticular protrusions, meticulously applied to a superior Plano-parallel glass plate in a random pattern. As light passes between these protrusions, it creates a sharp core image, ensuring accurate focusing and exceptional detail. This feature is particularly beneficial for photographers utilizing AF reflex cameras.
The light, subtly diverted by the mini-lenses, envelops the image in a diffuse halo of light, resulting in a delightful softness. This soft focus effect is perfect for portrait photography, especially when capturing highlights in blond hair, and can also be used to create ethereal landscapes.
The filter's glass is uncoated, a characteristic often found in special effects filters and acrylic filters, where a coating could potentially counteract the desired filter effect.
The 43mm Soft Pro Filter employs the standard B+W F-Pro filter mount, crafted from durable brass. This mount, thinner than its predecessor introduced in 2001, is compatible with wide-angle lenses, including most 24mm focal lengths on a full-frame body, without causing vignetting.
One of the key advantages of the F-Pro mount is its redesigned retaining ring. This ring, which holds the filter glass in place, is secured from the back rather than the front. This design ensures that the retaining ring remains secure, even when removing a tightly screwed on filter or lens hood.
In summary, the B+W 43mm Soft Pro Filter is a versatile and valuable addition to any photographer's toolkit, offering a unique way to add a touch of softness and dreaminess to your images.
