Canon EOS-3 Specifications





Type and Major Components

Type

35mm AF/AE single-lens reflex with focal-plane shutter and built-in motor drive


Picture Size


24 x 36mm


Compatible Lenses


Canon EF lenses


Lens Mount


Canon EF mount


External Flash


Compatibility: E-TTL autoflash, A-TTL autoflash, TTL autoflash


LCD Panel


Displays shooting, metering, AF, and film advance modes; shutter speed, aperture, frame counter, and battery level. Illumination provided.


Viewfinder

Type


Eye-level pentaprism


Picture Coverage


97 percent vertically and horizontally


Magnification


0.72x( -1 diopter with 50mm lens at infinity)


Dioptric Adjustment


-1 diopter (20mm eye relief)


Focusing Screen


Interchangeable (9 types)


Mirror


Quick-return half mirror (Transmission: reflaction ratio of 37:63). No vignetting with EF 1200mm f/5.6 lens or a shorter lens.


Depth-of-Field Preview


Enabled with depth-of-field preview button.


Autofocus

Type


TTL-AREA-SIR with a CMOS sensor


Focusing Points


Area AF with 45 focusing points (Custom Function No. 13 can limit this to 11)


Focusing Point Selection


Automatic selection: Focusing point camera-selected.
Manual selection: Focusing point manually-selected.
Eye Controlled Focus: Focusing point eye-selected.


Focus Modes


1. One-Shot AF: Autofocus stops when focus is achieved. AF lock enabled. Shutter releases only when focus is achieved.
2. Predictive AF with Al Servo AF: Tracks subject movement up to the start of exposure. Predictive AF enabled. The shutter can be released at anytime regardless of focus (predictive AF control takes effect during continuous shooting), no in-focus indicator (blinks at 8 Hz only if AF fails).
3. Manual focusing: Enabled with the focusing ring when the lens focus mode switch is set to MF (or M).
4. Full- time manual focusing: Enabled with the electronic focusing ring during continuous shooting (except during film exposure).
5. In- focus indicator: Lights in viewfinder and beeps. (Beeper can be disabled.)


AF Focus Indictor


Superimposed focusing point in viewfinder.


AF Working Range


EV 0-18 (at ISO 100)


AF Assist Method


Beam emitted automatically by the attached EOS Speedlite when necessary.


Exposure Control

Metering Modes


TTL max. aperture metering with a 21 zone silicon photocell.
1. Evaluative metering (linkable to any point)
2. Partial metering (approx. 8.5% of viewfinder at center)
3. Center spot metering (approx. 2.4% of viewfinder at center)
4. Spot metering (linked to focusing point at approx. 2.4% of viewfinder)
During continuous shooting with metering modes (3) and (4), the first shot is metered in real time and the meter reading is locked (AE lock) for subsequent shots in the same burst.
5. Multi-spot metering (Max. 8 multi-spot metering entries)
6. Center-weighted averaging metering


Metering Range


EV 0-20 (at 20&degC/ 68&degF with 50mm f/1.4lens, ISO 100


Exposure Modes


1. Program AE(shiftable)
2. Shutter speed-priority AE ( in 1/3,1/2 or full stops, safety shift enable with Custom Function)
3. Aperture-priority AE (in 1/3,1/2 or full stops, safety shift enabled with Custom Function)
4. Depth-of-field AE
5. E-TTL program flash AE (high-speed sync, FE lock, and wireless control enabled with 550EX)
6.A-TTL program flash AE
7. TTL program flash AE
8. Manual
9. Bulb


ISO Film Speed Range


ISO 6-6400 (Set automaticaly with DX-coded film at ISO 25-5000)


Exposure Compensation


1. Auto exposure bracketing (AEB) : +/- 3 stops in 1/3 stop increments. Standard exposure, underexposure, and overexposure sequence. Repeated bracketing enabled according to current film advance mode. With self-timer, all three bracketed shots are taken in the continuous shooting mode regardless of the film advance mode.
2. Manual exposure compensation: +/-3 stops in 1/3-stop increments set with the Quick Control Dial or exposure compensation button on the Main Dial.
3. AEB and manual exposure compensation can be set together.


AE Lock


Auto AE Lock: Operates in One-Shot AF mode with evaluative metering when focus is achieved.
Manual AE lock: AE lock button activates AE lock in all metering modes. Multiple exposures: Max 9 multiple exposures. Cancels automatically after all mutiple exposures are taken.(Cancellable and resettable at any time.)


Shutter

Type


Vertical-travel, focal-plane shutter with all speeds electronically-controlled.


Shutter Speeds


30 to 1/8000 sec in 1/3-stops, X-sync at 1/200 sec.


Shutter Release


Soft-touch electromagnetic release


Self Timer


Electronically controlled with 10 sec or 2 sec delay. Lamp blinks ( at 2Hz, then at 8Hz for the remaining two sec) Self-timer countdown on LCD panel. Self timer cancellable by turning the main switch to L.


Remote Control


Quick-lock, three-pin remote control connector provided (N3 type.)


Built-in-Flash

Flash Contacts


1. Hot shoe: X-sync direct contacts
2. Below camera balck latch: JIS B-type socket (threaded)
* Flash units connected to (1) and (2) can be used and fired simultaneously.


Film Transport

Film Loading


Automatic loading with a sprocketless system. After film is loaded and the back is closed, it advances to frame 1 automatically, taking about 1 sec.


Film Transport


Film advance system: Automatic film advance with built-in motor.
EOS-3 Single and Continuous shooting.
With Power Drive Booster PB-E2: Single, Low Continuous, and High Continuous.


Film Rewind


At the end of the roll, automatic film rewind with a built-in motor. Midroll rewind possible. Approx. 4.5 sec. for 24-ex. film and approx. 6.5 sec. for 36-ex. film Rewind noise: 59 dB (High-speed rewind), 49 dB (Silent rewind)
