For a direct contact shoe mount flash, the Canon Speedlite 133A is ideal. The Canon flash mounts directly into a camera's accessory shoe without the need for a synchronization cord. It was designed to make shoe mount flashes easy to use, automatically preparing the camera to take fantastic photographs in any lighting conditions. Compatible cameras are automatically set to flash mode (or f/4) when the pilot lamp begins to glow, and the Canon Speedlite 133A even automatically sets the shutter speed to an ideal flash synchronization speed (1/60 seconds). This Canon flash secures into place with a lock, making it stable enough to carry around, and the flash coverage fits the lens's view angle perfectly. The focal length is typically 35 mm. Colors are gently corrected with the use of a special color diffusion screen, and the camera can be set to take pictures every 30 seconds up to 100 flashes. The Canon Speedlite 133A even boasts an impressive recycling time of between 0.5 and 6 seconds, depending on the power source.
