Collapsible lens hoods are made of high-grade rubber. Their advan-
tage compared to xed lens hoods made of plastic or metal is that, in
their collapsed state, they protrude only a short distance. This means
that the lens hood can remain attached to the lens and, together with
the camera, will also t into a tight photo or standby bag.
Lens hoods are usually regarded simply as a kind of sun visor. In fact,
stray light occurs not only by sunlight obliquely striking the lens, but
also due to bright ground surfaces (snow, beach), diffuse light or (in
object photography) bright surroundings such as a light table. Block-
ing stray light can considerably improve the image quality of even
the most expensively coated lenses. B+W provides three collapsible
lens hood types for all standard lter diameters, from wide angle to
telephoto.
• The B+W Lens Hood 20 is designed for wide angle (zoom) lenses
with angles of view up to 0°. In the limit range of around 0° it
should only be used without a lter in order avoid vignetting. In its
collapsed state the hood increases the lens length by less than one
centimeter.
• The B+W Lens Hood 00 is tailored to standard lenses and short
telephoto focal lengths. Its inner ribbed surface enhances the
light-absorbing effect of the matte black surface. In its collapsed
state, the rubber hood increases the length of a lens by only one
centimeter (up to mm lter thread).
B+W metal lens hoods convey a reassuring, stable impression by
their very appearance. The black anodized aluminum reliably blocks
stray light, and the precision-engineered tubes have black inner ribs
for even greater absorption of unwanted light. Here too, three types
are available for numerous lter sizes:
• B+W Metal Lens Hood 0, suitable for wide angle (zoom) lenses
up to 0° diagonal angle of view
• B+W Metal Lens Hood 0 for standard lenses and short telephoto
lenses
• B+W Metal Lens Hood 60 with a narrower and longer tube for all
telephoto lenses
