AEC (AUTOMATIC EXPOSURE CONTROL) METERING AND NON-AUTOMATIC CONTROLS

The Autoreflex-T3 is the world's first professional Through-The-Lens metering 35mm Single-Lens Reflex cam- era to have fully automatic AEC exposrue control. The AEC meter system establishes contact to all KONICA Hexanon AR lenses by means of a meter-actuated coupling lever. When the shutter release is depressed, the spring loaded aperture in the lens is tripped to close to the limit determined by this coupling lever. This limit is the precise aperture required for a perfect exposure at that instant when you press the button.

With a KONICA Hexanon AR lens installed in your Autoreflex-T3 there is no need to waste time before shooting to match the needle to a mark. You only need to focus and compose, then press the shutter release - remaining assured all the time that correct exposure is being taken care of. Full concentration can thus be made on the spontaneous or esthetic needs of your photography. In actuality, the KONICA Autoreflex-T3 offers not one but three optional methods of arriving at the correct of desired exposure.

AEC Metering: With a KONICA Hexanon AR (Automatic Exposure) lens, the needle in the viewfinder serves only to let you know at which f/stop the fully automatic metering system will make the picture for you. Shutter and diaphragm are cross-coupled. Thus if you choose a high shutter speed to stop action, the diaphragm will be set for a wider opening automatically. On the other hand, should you need a smaller stop for greater Depth-of-Field, simply turn the Shutter Speed Dial (20) to a slower speed. The needle in the information center of the Viewfinder will keep you informed. At the same time, you can read the shutter speed setting below the viewing area (see page 33).

Stopped-Down Exposure Metering: With KONICA and other lenses having manual or preset diaphragm (not AE), as well as with extension rings and bellows, the Stopped-Down method is used. Here the exposure is read at the actual aperture used to make the picture. The needle in the Control Center is then simply brought to the Index Mark opposite the f/1.4 figure. This can also be done by changing the shutter speed setting. Leterally thousands of lenses can be used with this system. In addition to KONICA Auto- Reflex lenses, lenses in mounts for KONICA FP, Pentax/ Praktica, Exakta/Topcon and Nikon/Nikkormat can be used for the Stopped-Down metering with the Autoreflex- T3 via their respective KONICA Lens Adapters.

Manual Exposure Settings: Should you have some special exposure idea in mind, you need only move the diaphragm ring of your KONICA Hexanon AR lens from the AE setting to any f/stop desired. Thus, with this and the other metering systems just discussed, exposure with the KONI- CA Autoreflex-T3 becomes a versatile tool which gives you freedom to exploit its automation or to choose other exposure methods. (See page 39)

NOTE: The KONICA Autoreflex-T3 does not take any fully automatic AE aperture lens prepared for the Autoreflex as it is. Make sure that you sue it after it has been remodeled into a lens for use on the Autoreflex-T3 (with f-numbers). Remodeling work is quite simple.
