Canon Speedlite 244T Camera Flash Instructions

Canon Speedlite 244T Camera Flash

Nomenclature

• The Canon Speedlite 244T is an au- tomatic, electronic flash unit de- signed exclusively for the Canon T- series cameras. The 244T sets both the shutter speed and aperture automatically, making flash photography incredibly simple. When the “P” in the viewfinder starts to blink, all you have to do is attach the unit to the camera and turn the main switch on for beautiful flash pictures.
• An automatic exposure flash has a sensor which measures the light reflected from the subject and cuts off the flash emission automatically when the subject has received the proper amount of light.
• Use this flash when the green “P” starts to blink.

Loading the Batteries

Use two new size AA alkaline- manganese (LR6/AM-3) or Ni-Cd batteries. Carbon- zine batteries may also be used, but their life is shorter. In tem- peratures below 0°C (32°F), use fully charged Ni-Cd batteries for best re- results.

1. Slide the battery chamber cover off.
2. Load the batteries so that their contacts are in the directions dicated by the diagram inside the battery chamber.
3. Once the batteries are loaded, slide the battery chamber cover back on while pressing the batteries down. Make sure the cover’s tab fits into the corresponding groove on the flash body.

• Remove the batteries if you do not expect to use the 244T for about three weeks or longer.
• When using Ni-Cd batteries, please note that each brand has its own terminal system. Be sure to use the type which is suitable for this flash. Re-charge Ni-Cd batteries according to the manufacturer’s instructions.

Setting the ISO Film Speed

• Set the ISO film speed corresponding to the film in use.
• Use only ISO 100 or 400 film with this flash. Other films cannot be used.
• The number after ISO is the equivalent ASA number.

Mounting the 244T on the Camera

• Insert the Speedlite into the camera’s accessory shoe. For proper electrical contact, make sure it is pushed in all the way.

Taking Flash Pictures

1. Make sure that the lens is set to the “A” mark, and that the camera is set to “PROGRAM.”
2. Turn the main switch of the flash ON.
3. Make sure the pilot lamp lights up. When the “ ” mark lights up, the shutter speed switches to X-sync (1/60 sec) automatically.
4. Compose the picture and focus on the subject.
5. Press the shutter button halfway to activate the viewfinder information display. When the “ ” mark and the “p” mark (T50, T80) or the selected aperture value (T70) light up, you can take a picture.
   • When the shutter button is pressed halfway, the Speedlite emits near-infrared rays, and an aperture is automatically selected according to the shooting distance and reflectivity of the subject.
6. Set the main switch to OFF when flash photography is finished.

Notes

1. If the subject is too far from the flash, the T50’s and T80’s green “P” or the T70 lens’ full aperture value will blink rapidly (8 times per sec) to warn you. (The” ” remains solid.) Move closer to the subject until the “p” stops blinking. Once you have found a suitable shooting position, be sure to remove your finger from the shutter button and re-focus the subject. Then you can take the picture.
   If you do not remove your finger from the shutter button after changing your position, exposure will be incorrect, since exposure is set each time the shutter button is pressed halfway.
2. Please note that the closest shooting distance is 0.5m with ISO 100 and 1m with ISO 400 film.
3. The flash auto shooting distance range is greater when using ISO 400 film. Thus you can photograph a subject that is up to 11.4m (37.4 ft.) away when using brighter (f/2.8 or larger) lenses.
4. When using a lens with a maximum aperture of f/3.5 or smaller, keep in mind that the flash auto-shooting distance range will be less than when using brighter (f/2.8 or larger) lenses.
5. Rapid continuous shooting with the T-series cameras is not possible when the 244T is mounted.
