To mount the Konica Accessory Clip 3, unscrew the eyepiece cover, position the Accessory Clip atop the
camera, fit the eyepiece cover to the Accessory Clip, and re-attach the eyepiece cover by screwing it on
(clockwise).
Determining Exposure for Flash Pictures
Manual settings are required for flash shooting. The AEC system is not applicable. Exposures are usually
calculated on the basis of "Flash Guide Numbers" furnished by the makers of flashbulbs (and flashcubes) or
electronic flash units. To find the correct f/stop to use, the guide number is divided by the flashto-subject
distance. Thus if the guide number is 110 and the subject is 10 feet away:
If in doubt, refer to the table above as to which shutter speeds are useable with a specific type of flash
illumination. Guide numbers for flashbulbs are generally printed on the package. Electronic flash guide
numbers are generally furnished by the maker of the unit. Guide numbers are exactly that - they can serve as
guides but all other existing light will affect your exposures to some extent and you should make allowance in
your settings for intermediate f/stops which also click into place.
When the shutter speed dial is set at "B", the shutter win remain open as long as the shutter release is held
down. As a result, exposures longer than one second--as long, in fact, as several
hours
may be taken at night, or
in dimly- lit places where there is no moving subject. If an exposure of more than several seconds is desired,
attach a Konica Cable Release (available from your dealer) to the Shutter Release Button (1). Set the shutter
speed dial to "B". Press down the cable release "plunger", and hold it down for as long an exposure time as is
desired. When the cable release plunger is released, the shutter closes.
Manual diaphragm settings must be made when the Copal Square-S shutter is set at "B". The AEC (AK) setting
on the lens is not used. Instead the lens is set manually at the desired f/stop.
It is necessary that you use a tripod or other support for "B" time exposures and all other exposures longer than
l/30th second. Use of a cable release will minimize jarring the camera.
ACCESSORIES
· KONICA Filters
Konica Filters help make more natural looking pictures in black and white or color. They may also be used to
create special effects. They are made with the same precision as are Konica lenses. Since exposure is read
through-the-lens in the Konica Autoreflex-A3, the filter "exposure factor" is computed by your Konica
automatically.
· Lens Hoods
Prevent stray light from striking lens surfaces and causing unwanted reflections. Each Konica Lens Hood is
specifically calculated and shaped to give maximum protection to the lens on which it is used.
