1. (white on blue background) - multi-spots metering indicator, H/S control indicator, and remaining frame display.
2. (White on blue background) FE Lock indicator when the Speedlite 300TL is used with the camera in the FE lock mode.

• Light Metering System: Through-the lens (TTL) full aperture metering for FD lenses, using silicon photocell (SPD). Three selectable metering patterns: Center-weighted average metering, partial area metering, and spot area metering. When using lenses or accessories without FD signal pins, only stopped down metering may be used.
• Exposure Modes:

1. Shutter priority AE with selectable Safety Shift function (ON/OFF possible)
2. Aperture priority AE with selectable Safety Shift function (ON/OFF possible)
3. Standard program AE
4. Variable shift program AE (selectable out of 7 programs)
5. Manual
6. Stopped down AE
7. Stopped down (fixed index) metering
8. Flash AE (possible with specified Canon Speedlites)

• Meter Coupling Range: EV 0-20 (with ISO 100 film and a 50 mm f1.4 lens)
• Film Speed: ISO 6- 6400. (ISO25-5000 is automatically set by 1/3 step according to DX code standard). Also can be set manually.
• Exposure Compensation:

a. Exposure compensation index: +/- 2 steps by 1/3 increment.
b. H/S control: +/- 4 steps by 1/2 increment (can only be used during spot metering, and in the FE lock mode with the Speedlite 300TL)

• Shutter Vertical travel metal focal plane shutter: All speeds electronically controlled. Front and back curtains controlled by separate quick-return permanent magnets.
• Shutter Speeds: 1/4000 - 30 sec. and bulb. (X-sync = 1/250 sec.) Can also be set in 1/2 step.
• Self-Timer Electronically controlled, with a delay of either approx. 10 sec. or approx. 2 sec. Indicated by blinking red LED operation confirmation indicator.
• Film Loading: Automatic. After the film has been positioned and the back cover closed,the film is automatically advanced to the 1st usable frame and then automatically stopped. (approx. 2 sec.). The frame counter displayed then read "1".
• Film Winding: Automatic. A built in coreless motor is used exclusively for film transport. Continuous shooting is possible. Confirmation by the film transport bar marks on the LCD display panel.
• Film Winding Mode: Three selectable modes, S (single exposure), H (max. 4.5 fps), and L (max. 2 fps). When operating in H mode, automatically switches to L mode when battery power drops below prescribed voltage to extend shooting capacity.
• Film Rewind: Automatic. A built in coreless motor is used exclusively for film rewind. Automatically starts when the end of the film is reached and then automatically stops (approx. 8 ssc. with 24 exp. film). Manual film rewind is also possible by pressing the manual rewind button.
• Flash Contact: Coupled directly to the camera by means of the X-sync contact on the accessory shoe. When using the Speedlite 300TL either first shutter curtain synchconization or second shutter curtain synchronization can be set.
• Automatic Flash: (When the Speedlite 300TL is used and the camera is set to a program AE mode):

1. A-TTL flash-auto: Using A-TTL program and the near infrared pre-flash of the Speedlite, the correct aperture value is automatically set according to the shooting distance and subject reflectivity. X-sync speed is also automatically set between 1/60 -1/250 sec. upon flash charge completion. TTL control system which meters the light reflected from the film surface. Automatic fill in flash is possible.

2. FE lock TTL flash-auto: The camera's FE lock program automatically sets the aperture. The main flash tube produces pre-flash and the reflection from the subject is measured by TTL spot metering and is entered into memory. X-sync speed is also automatically set between 1/60 -1/250 sec. upon flash - charge completion. Automatic fill flash is possible.

• Remote Control: Possible. With three terminal contact for remote control. Remote Switch 60T3 is required.
• Multiple Exposure: By pressing both the shooting mode selector and the metering mode selector at the same time. Continuous multiple exposure is possible. Reset clear during shooting and preset up to 9 exposures are also possible. Automatically cleared upon completion of preset exposures.
• Eyepiece Shutter Provided.
• Exposure Preview Button: All LCD / LED displays can be turned ON or OFF. LCD display to the right of the viewfinder and the display panel can be illuminated by the built in illumination lamp.
• LCD Panel: Displays only the information required at the time, e.g. shooting mode, metering mode, film winding mode, shutter speed, aperture, film speed, frame counter (additive type), Self timer operation time, bulb operation time, battery check, etc.
