Standard of judgment
·The field of viewfinder must be 80% or
more and less than 100% against the
picture image in vertical and horizontal
directions.
Check the field of viewfinder with the negative
film which has been used at W end 2.94m and T
end 2.91m (W/T 3m from film surface).
·The visual field must not be inclined
extremely.
·Parallax: It must be within the picture
to be taken.
·In near distance photography, the whole
visual field must be taken at the top,
right and left.
The bottom must not be protruded extremely.
At T 0.61m (0.7m from F surface) and macro 0.24m
(0.7m from F surface), take a picture according
to the "d" near distance compensation frame.
·Diopter: -0.7 diopter +0.5/-1
Measure T/W in a distant view of 30m or more
with a diopter telescope.
·Diopter difference between image and frame:
0.7 diopter
Diopter difference of T/W: Within 1.0 diopter
Perform measurement with WIDE as standard.
·Magnification
W 0.336±15%
By using a diopter telescope, measure the dis-
tance between two points of 50m or more away
from each other when a camera is used and when
a camera is not used.
·The AF beam center position must be within the
target mark.
In a 3m distance, check the misalignment for
the AF zone and AF beam center of the finder.
·There must be no optical axis misalignment.
In a 3m distance, mark the center of the target
mark at WIDE. At TELE, the center of this mark
must not deviate from the target mark.
60mA or less
Measure the electric current when OK LED
lights after BC.
380mA or less
Measure the electric current at luminance with-
out speed light flash.
150mA or less
Measure the electric current when self-timer is
operating.
420mA or less
Measure the electric current when one frame is
being advanced during FFS.
460mA or less
Measure the electric current when film is being
rewound.
10µA or less
Measure the electric current under the auto.
power OFF condition.
10µA or less (40mA or less at the last stage of
speed light pressurization)
Measure the electric current after 1 minute
since the main switch was turned on.
