CANON AE-I PROGRAM SECTION 1 SPECIFICATIONS AND OPERA TION

• TYPE: Electronically controlled 3Smm SLR with choice of three operation modes_program (automatic shutter speed and diaphragm opening) , shutterpreferred , and manual. To mode, turn the diaphragm-setting to auto and set the knob to program. The P"LEDin the finder should turn on when you depress the release button part way. At ASA 100, the programmed mode goes from EVI (f/ 1.4, | second) to EVI8 (F/ 16, 1/1000). For shutter-speed preferred, leave the lens at autoand select the desired shutter on the knob. For manual, turn the diaphragm-setting to a manual f/stop setting: The M LED in the finder should turn on when you push the release button part way. speed ring speed speed speed ring

• SHUTTER: Vertically tra electronically controlled focal-plane shutter. The second-curtain magnet holds the second curtain for the length of the exposure time. Since the shutter uses a digital timing circuit, the slowest speed is 2 seconds even with the lens covered at the program mode. Curtain-travel time: 10.Sms (34mm distance), 9 (32mm distance)_ veling; 9ms

• METER: Full-aperture, center-weighted meter with LED readout. The LED display indicates the aperture the camera will automatically set at the program and shutter-speed-preferred modes. In the man ual mode, the LED display indicates the proper aperture for the light conditions. Turn on the LED display by pushing the release button part way or by pushing in the preview button. In the program mode, the "P" LED flickers if the camera must program shutter speed of ! / 30 or slower. The 16 " LED flickers for overexposure indication, and the LED for the maximum aperture flickers for underexposure indica-tion_ "1.4" LED flickers if the camera cant set large enough aperture for the shutter-speed settingand light conditions. The LED brightness changes with the brightness of the field of view. ing

• MEMORY HOLD: The AE lock button locks the exposure information in memory for unusual lighting conditions. Take a reading from the subject by pushthe release button part way; then depress the AE lock button. The exposure information remains in memory for as long as you the release button partially depressed it'$ not necessary to hold in the AE lock button The information is cleared from memory when you make an exposure or let up the release button_ ing keep

• BATTERY: One 6-volt PX28 or 544 (negative ground). To test the battery, push the battery-test button_ If the battery is good, the piezo beeper will The frequency of the beeper indicates the battery condition; the frequency decreases as the battery voltage With 4.8V or more applied to the battery terminals, the beeper frequency is 6.5 Hz. The fre quency decreases as the voltage decreases, reaching 1 Hz with 3.5V applied. The piezo does not beep too low for proper operation (3.3V or lower): To replace the battery, first remove the grip at the front of the camera disengage the latch to open the battery compartment. beep. drops. applied palm Then

• SELF-TIMER: Electronic self-timer providing delay of 10 seconds. Set the self-timer by moving the SL (self, lock) lever to the "S position. Push the release button to release the self-timer. During the self-timer the piezo beeps at a frequency of 2 Hz for the first 8 seconds and 8 Hz for the final 2 seconds. delay,-

• FLASH SYNCHRONIZATION: X-sync only, flashcord terminal and hot shoe. The Canon dedicated-flash units automatically set the aperture and the flash speed. Regardless of the speed-knob setting (except at bulb), the shutter speed switches to 1/60. When the flash unit charges, the lightning-flash LED at the bottom of the finder display turns on; the LED simultaneously shows the f/stop which the flash unit will set. With the 1884 flash unit, the LED display also shows proper flash exposure after you release the shutter. If the flash was able to supply the proper amount of light, the lightning-flash LED blinks for two seconds after the exposure. stop

• LENS: Accepts all Canon breechlock
