Exposure For Synchroflash Pictures
The Electric-Eye system is not usable for synchroflash photography, and exposure is determined according to the Manual Aperture
Scale ''11). The required lens aperture (f-number) is computed by dividing the guide number of the used synchroflash bulb or electronic
light with the taking distance. For example, in the event that a bulb of Class M is in use and the guide number for the shutter and film
speeds is 75 and that the taking distance is 9 feet, the lens aperture (fnumber) will be about 8, whereas: 75-9=8 As regards the shutter
speeds with which each synchroflash bulb or electronic light is synchronized, refer to the table.

The guide number is shown on the package of each synchroflash bulb. A table of guide numbers is available depending on the
synchroflash gun. Here, use this table.
LENS INTERCHANGE
To dismount the lens
To dismount the lens, depress the Lens Interchanging Button (4), when the silver part of the lens barrel is gripped and the
barrel is turned counterclockwise and pulled out of the camera as the red dots of the barrel and camera are aligned with each
other.
NOTES:
Q When the lens is detached from the camera, do not touch the inside of the camera.
Q Prevent dust from coming into the camera and falling on the dismounted lens and see to it that the lens surface is neither
scratched nor marred with fingerprints.
To mount a lens on the camera
To mount a lens on the camera, bring the red dot of the lens in line with the Lens Mount Index Mark (red dot) (7) of the lens
barrel and correctly sink it into the camera. Then grip the silver port of the lens barrel and gently turn the lens clockwise until it
clicks into position.
