(1)
 CdS Magnifying Hood
This is a spot metering finder 
with a CdS exposure meter 
incorporated in the 
magnifying hood. Since the 
meter measures light which 
passes through the lens, the 
correct exposure setting is 
easily obtained. A 
compensating exposure factor 
need not be considered even 
if the bellows is extended. 
When employing a color 
filter, however, compensating 
exposure must be made by 
considering the filter 
exposure factor. (By 
attaching the same color filter 
to the viewing lens, such 
compensation is 
unnecessary.)

 Prism Finder
As with the magnifying hood, 
this prism finder may be used 
instead of the focusing hood. 
Through this prism finder, the 
image on the ground glass 
focusing screen appears 
exactly as the subject is seen. 
Really an indispensable 
accessory for eye-level photo-
journal photos or candid 
shots. 
Magnification of this finder is 
approximately 2.5 times the 
image on the ground glass 
focusing screen, particularly 
bright and clear.

 CdS Porrofinder
This is a Porrofinder with built-
in CdS exposure meter. Match 
the index needles within the 
finder by turning the dial on the 
back of the finder, and read the 
dial scale. This device measures 
the amount of light traveling 
through the viewing lens, 
offering correct exposure setting 
even for amateurs.
Eye Correction Lens
This lens, designed to correct 
visibility, is installed inside the 
eyepiece ring of the CdS 
Porrofinder, or Prism Finder. 
Nine types of lenses are 
provided from +2.5 to -2 diopter 
(each diopter is +2.5, +2.0, +1.5, 
+ 1.0, +0.5, -0.5, -1.0, -1.5, and -
2.0). 
When installing the lens on the 
finder, hold the milled portion of 
the eyepiece ring with the thumb 
and finger, and turn it 
counterclockwise to remove the 
ring. When the lens is a plus 
(convex) lens, position it with 
the flat surface outside, and 
when it is a minus (concave) 
lens, place the concave surface 
on the exterior, then screw the 
ring into its original position.
