FOR SAFETY'S SAKE
Your Konica camera reflects the latest advances in photographic engineering and is designed to give you
dependable, trouble-free use. Operation is probably somewhat different from cameras which you have
previously owned. For this reason, it is strongly recommended that you shoot a "test" roll of film, have this roll
processed, and examine the pictures before exposing additional rolls. The processed "test" roll will verify that
you are using your new equipment correctly, and allow you to make any necessary changes in operating
patterns; additionally, it will confirm that all camera functions are operating perfectly. In the event you are
leaving on a trip (or some equally important events shortly, your Konica dealer can recommend the fastest way

  • Page 9: Shutter Speeds And Lens Apertures

    SHUTTER SPEEDS AND LENS APERTURE Your Konica Autoreflex-A3 has a metal Copal Square-S focal plane shutter, with the control dial conveniently located on top of the camera. This unique shutter is noted for exceptional accuracy even under extremes of temperature and climate, and is virtually impervious to damage or deterioration in normal use. This shutter, because of its exceptionally fast (7.5 milliseconds) traverse time, permits use of electronic flash at all speeds to and including l/125th second (this speed is marked in red on the shutter speed dial).

  • Page 10: Control Center" Viewfinder

    Automatic Operation: With a Konica Automatic Hexanonlens on your Konica Autoreflex-A3, just check the indicator needle in the viewfinder, which shows the exact aperture the camera is selecting...and shoot! The automatic aperture mechanism sets this lens opening for you at the moment of exposure-and you can concentrate on your subject, instead of your camera.

  • Page 11: Using Automatic Exposure Control (Aec)

    The upper red band (40) also shows you the maximum aperture of the lens in use; in the illustration on the opposite page, an f/1.7 lens is on the camera, so the band rests between f/1.4 and f/2. When you mount a faster or slower lens on the camera, this band will more up or down to show the new maximum aperture (and, simultaneously, the new underexposure zone.) "Your Konica's sensitive through-the-lens meter automatically determines correct exposure over an...
  • Page 12 Full Aperture AEC Operation: The figures in brackets in the chart at under show actual values of the dots between marked numbers on the film speed indicator. 1. Set the Film Speed. Lift the outer collar surrounding the Shutter Speed Dial (15) and turn it until the correct ASA number appears in the Indicator Window (13).
  • Page 13 3. Check Aperture Ring. Make certain the Aperture Control Ring (9) is at the AE (EE) position as shown. If lens is not on AE(EE) position, your picture will be exposed at the opening shown on the aperture ring. irrespective of the f/stop indicated in the viewfinder.
  • Page 14 UNDER/OVER-EXPOSURE SAFEGUARDS If the meter needle goes to the upper red band (shown above for the three standard lenses), choose a slower shutter speed. If, at the slowest shutter speed (1 second), the needle's still in the red zone, there's not enough light to get a perfectly exposed picture.
  • Page 15 SEMI-AUTOMATIC OPERATION WITH UNCOUPLED LENSES/ACCESSORIES Your Konica's through-the-lens metering system works perfectly even with non-automatic lenses and accessories, which do not couple to the camera's automatic exposure mechanism. (Example: Pre-set lenses, mirror lenses, lenses from other cameras used with Konica adapters, even extension rings or bellows.) Here's how to use your Autoreflex-A3 in these situations: 1 Set the Film Speed.
  • Page 16 SEMI-AUTOMATIC OPERATION WITH UNCOUPLED LENSES/ACCESSORIES: REMINDERS When using the stop-down metering system with uncoupled lenses or accessories, keep in mind that the f/stopscale in the viewfinder no longer applies; neither do the under or over-exposure warning bands. If the needle's above the Index Mark (39) as shown (above, left) there's not enough light; ff it's below this mark (above, right)there's too much light.
  • Page 17 Extremely Dark Backgrounds: In the illustration at left, a relatively light subject is being photographed against a very card background. Here again, taking a "close-up" reading, holding or locking that reading, then going back to the desired position and taking the picture, will automatically provide a professional close-up exposure reading and a perfectly-exposed picture.

  • Page 18: Depth-Of-Field Control

    With Microdiaprism Focusing Screen: Turn the Focusing Ring (6) of the lens until the image within the center of the viewfinder (44) is sharpest and clearest. (When you're out of focus, this central area - composed of hundreds of microscopic prisms - appears quite hazy and unsharp.) Under almost all conditions, this precision focusing screen works easily and with great accuracy.
  • Page 19 Using Depth-of-Field Scale on Lens: On the Depth-of-Field Scale, f/stop markings identical to those on the Manual Aperture Scale (7), are repeated to the right and left of the Distance Scale Index Mark (46). The Depth-of-Field for any focused distance will be found between any two identical f/stop markings on the Depth-of-Field Scale.

    1. Depress the Film Rewind Button (35). Once it is depressed, the button remains in place. 2. Lift up the Film Rewind Crank (18) and turn it clockwise at moderate speed in a continuous motion. An arrow on the Rewind Crank indicates correct direction toward. 3.
