Software Development Kit
The Canon EOS Digital Camera Software Development Kit (EDSDK) and the Camera Control API (CCAPI) are available on select Canon cameras1 and enables developers to integrate select Canon cameras directly into their software application solutions, giving them access to remote control and communication functionality of the camera. The EDSDK supports USB communication on Windows, Macintosh, and Linux operating systems, while the CCAPI uses Wi-Fi (Ethernet on select cameras) and can be used with almost any OS.
The EDSDK and CCAPI (along with other SDKs and APIs) are provided free of charge and more information can be found at https://www.usa.canon.com/support/sdk.

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°C/ 68°F 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 automatically 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 multiple exposures are taken.(Cancellable and resettable at any time.) |

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

Shooting Capacity | While using an EF 50mm f/1.4 USM lens, 1/1000 sec. shutter speed, Eye Control, and continuous shooting mode, the following operations for each frame were executed: The lens was focused from infinity to the minimum distance and back, the shutter button was pressed halfway for 6 seconds, the picture was taken, and the settings were retained for 2 seconds. This operation cycle was repeated in continuous shooting mode and high-speed film rewind was used at the end of each roll. |
