Line

The Standard Filter Mount F-Pro has high

mechanical stability despite its shallow

design. It can be used on most wide-an-

gle lenses without the danger of vignett-

ing. However, exact data regarding focal

length and angle of view limitations are

not possible because vignetting depends

not only on the height of the ﬁ lter mount

and the angle of view, but also on the

tube design of the front of the lens. As a

guide, this ﬁ lter mount can be used with-

out vignetting on 35 mm camera lenses

(approx. 63° diagonal angle of view). In

addition, most wide-angle lenses with

28 mm (approx. 75° angle of view) and

in many cases even with 24 mm (approx.

84° angle of view) can be combined with

the F-Pro mount without the risk of vi -

gnetting. The same angles of view apply

to lenses in digital cameras. Despite the

thinner design, others ﬁ lters, snap caps

or lens hoods can be attached easily and

safely to the front thread.

Another advantage of the new F-Pro ﬁ lter

mount: the ﬁ lter glass is no longer held in

place from the front, but from the back

by the retaining ring. This prevents the

retaining ring from being accidentally

loosened during the removal of an addi-

tional ﬁ lter or a lens hood that has been

screwed in too tightly.

Available in Ø 24, 25.5, 27, 30.5, 35.5, 37,

39, 40.5, 43, 46, 48, 49, 52, 55, 58, 60, 62,

67, 72, 77, 82, 86, 95, 105, 112 and 122.

Digital photography in particular beneﬁ ts

from quality ﬁ lters. The Digital Pro ﬁ lter

mount is geared specially to the design

and mount diameters of digital cameras

and camcorders. The silver, hard chrome-

plating on the outside follows the pale

color trends of digital cameras and forms

a harmonious unit with the lenses. In terms

of its design, this high-quality mount is

based on the F-Pro model. There are cur-

rently 13 mount sizes available between

30 and 62 mm.

B+W Digital-Pro mounts are available

with the ﬁ lter types 010, 010 MRC, 486,

Käsemann-type circular MRC and C-Pol

polarizing ﬁ lters.

With Ø 30, 30.5, 35.5, 37, 39, 40.5, 43, 46,

49, 52, 55, 58 and 62.

In the super-wide-angle range even nar-

row mounts such as the XS-Pro series

cannot completely prevent vignetting.

For such extreme special cases we have

the B+W oversized ﬁ lter mount extra-

wide (EW). The mount has oversized di-

mensions. The mount and the ﬁ lter glass

protrude beyond the screw-in thread on

the lens side. Even with ultra-short focal

lengths with a narrow tube, this safety

gap ensures that light incident at a highly

oblique angle in the corners of the image

is not impeded. This is necessary in partic-

ular for adjustable view and large-format

cameras, as well as for special panorama

cameras.

Available in EW Ø lens: 62, 67, 72, 77, 82,

86, 95, 105, 110, 112 and 122.
