Canon Speedlite 155A - Good Condition | The Intuitive Flash Companion for the A-Series and Beyond

Introductory Paragraph The Canon Speedlite 155A is the definitive choice for the enthusiast who values a seamless and reliable lighting solution for their vintage Canon system. Originally designed to complement the legendary A-series cameras, such as the AE-1 and A-1, this flash is celebrated for its specialized interface that automatically sets the camera's shutter speed and aperture when the pilot lamp glows. Because it features a sophisticated thyristor circuit, it serves as an incredibly capable tool for photographers who need fast recycle times and consistent exposures without the complexity of manual calculations. Whether you are shooting indoor events or adding a fill-flash to outdoor portraits, this Canonprovides the optical brilliance and electronic synergy that made it a staple accessory for film photographers in the late 1970s.

Key Features

• Intelligent Automatic Exposure Control via an integrated external sensor for effortless flash photography.

• Dedicated A-series integration, automatically communicating with compatible Canon bodies to set the correct sync speed.

• Energy-efficient Thyristor circuitry, significantly shortening recycle times and extending battery life for long shooting sessions.

• Dual Auto-Aperture settings (Red and Green modes), allowing for a choice of depth-of-field while maintaining perfect exposure.

• Clear, easy-to-read calculator dial on the rear for rapid manual setting adjustments when needed.

• Large, tactile Pilot Lamp/Test Button for instant verification of flash readiness and manual triggering.

• Compact and lightweight design, ensuring the camera remains balanced and portable for handheld use.

Condition Report Good condition. Body: The Canon flash unit (S/N: T703) shows normal signs of light use and minor cosmetic surface wear consistent with its era. The battery compartment is clean and free from corrosion. Sensor/Optics:The flash window is clear and free from significant yellowing or cracking. The external auto-sensor is clean and unobstructed. Mechanics/Electronics: All electronic functions have been fully tested. The flash fires reliably in both Auto and Manual modes, and the recycle alert communicates correctly with the camera's viewfinder system.

Specialist Note "The 155A is a must-have for any AE-1 owner. What I love about this model is its simplicity; it takes all the guesswork out of flash photography by talking directly to the camera. It’s a rugged, honest piece of Japanese engineering that still performs beautifully decades later. Even if you aren't using an A-series body, it works as a fantastic, compact 'auto-thyristor' flash on almost any camera with a standard hot shoe. For anyone looking for a reliable, vintage-correct flash that is incredibly easy to operate, this Canon is a top-tier choice."
