Short Description
The Canon Speedlite 133A is an automatic eletronic, direct contact flash designed especially for the Canon A-1, AE-1, AV-1 and AT-1 single-lengs reflex cameras. It mounts directly into the accessory shoe of the camera where it couples directly with the camera without the need for a synchronization cord. It is intended primarily for use with ASA 80, 100 or 400 film and with lenses having a speed of f/4 or faster.

Lacking the usual, complicated calculator dial, the Speedlite 133A makes flash photography about as easy as it can be. The A-1 or AE-1 with an FD lens on “A” and with ASA 80, 100, or 400 film, is switched to the flash mode automatically when the pilot lamp glows - no special setting necessary. With the AV-1 or AT-1, setting the len’s aperture ring to f/4 is all that is required. On all these cameras, the shutter speed is set automatically to the flash synchronization speed of 1/60 sec. when the pilot lamp glows.
Compact and lightweight, the 133A is great for super-simple automatic flash shooting with other cameras as well.
