FOREWORD
The PB-5BellowsFocusingAttachmentis a simplified
version of the top-of-linePB-4 model. The bellows
extendsfrom 43 to 185mm for reproductionratios
rangingfrom 1:1.2 to 3.6X with the 50mm f 12lens
(1.6X to 4.4X when the lens is mounted in reverse
using the accessoryBR-2 ring). The lens panel and
camerapanel move independentlyfor easyfocusing
and operatingconvenience.And the camerabody can
be rotated 90" for horizontal or vertical format
picturesat any positionon the rails.
The PB-5 acceptsaccessoryslide copying adapters
PS-5and PS-4.

To calculateexposurecompensationin terms of shutter
speedrather than f-stopsfind the exposurefactor from
the graphsand multiply it by the exposuretime. For
example,if normalexposureat 1 : 1 reproductionratio
with the 50mm f l2is 1/8 second,the correctedexposure
will be 1/8 multipliedby 4, or 112second.
Note: When using a lens of retrofocus or telephoto type, the
differencein pupillary magnification must be taken into account
to establish the correct exposure. The pupillary magnification is
the ratio of the exit pupil diameter to that of the en1ran"" pupil.
The folfowing formula is used to calculate the exposure factor
when a retrofocus or telephoto type lens is used in normal
position:
Exposure factor = (1 + Mlv12
(where V = pupillary magnification)
Whenthe lens is in reverseposition:
Exposurefactor ='llv2 (l + vw12
To avoid complicated calculations,use the graphs on pages22 to
25 to determine correct exposure in aperture values.The graphs
are computed to take into account the pupillary magnification.
