Using the Lens with the Auto Extension Rings No. 1 and No. 2
1.
Focus the lens.
The Floating Ring may be set at any position.
2.
Determine the bellows extension using the Bellows Extension Scale (mm) on the left side of the
camera, Fig. 1 (1).
3.
Align the bellows extension on the Floating Scale’s
Red No. 1 + No.2 Scale
with the red Index
Mark.
For example, if the bellows extension is 25, you would align 25 with the red Index Mark,
Fig. 5.
4.
Refocus the lens.
The maximum extension on the
Red No.1 + No. 2 Scale
is 15mm, at which life-size images can
be created. Extensions beyond 15mm will result in image-quality deterioration.
When creating live-size images, set 15mm on both the
Red No. 1 + No. 2 Scale
and the
Bellows Extension (mm) Scale
, and then move the camera back and forth to achieve focus.
Depth-of-Field and Magnification
1.
After focusing the lens, use the Distance Scale on the left side of the camera, Fig. 1, to determine
the film plane to subject distance.
2.
Set this number opposite the DOF Distance Scale’s Index Mark.
The depth-of-field and
magnification can be read from the DOF Distance Scale.
Magnification is expressed in ‘MAG’ numbers.
A MAG number is the reciprocal of the
magnification. For example, a MAG number of 50 indicates that the subject is being
photographed at 1/50 its size, etc.
Depth-of-field can be observed by holding the lens’ Depth-of-Field Preview Lever on the lens, and
then observing the depth-of-field through the viewfinder. Moving the lever stops the lens down to
its working aperture; releasing the lever return the lens to full aperture.
Exposure Compensation
Exposure compensation is expressed in STEP values, which are listed below the MAG Numbers on
the DOF Distance Scale.
A STEP value of 0.5 indicates that the exposure compensation is
½ stop;
either open the aperture
by ½ stop or decrease the shutter speed by ½ stop. A STEP value of 1 indicates that the
exposure compensation is
one stop;
either open the aperture by one stop or decrease the shutter
speed by one stop.
If you are using an AE Prism Finder, setting exposure compensation is unnecessary.
Time Exposures
1.
Press and hold the Time Exposure Lever Release Button.
2.
Move the T Lever all the way in the direction of the arrow, and then release the Time Exposure
Release Button.
The T Lever will lock in its time-exposure position.
3.
Press the Shutter Release Button, the shutter will open and remain open until you release the
Shutter Release Button.
