Canon Speedlite 550EX - Good Condition | The Powerful Professional E-TTL Master Flash

Introductory Paragraph The Canon Speedlite 550EX is the definitive choice for the enthusiast who values professional-grade power and sophisticated wireless control. As the flagship flash of its era, it was the first to fully support Canon’s E-TTL (Evaluative Through-The-Lens) metering system, ensuring perfect exposures even in complex lighting environments. Because it features a high guide number and the ability to act as a wireless Master or Slave unit, it serves as an incredibly capable tool for building a creative multi-flash studio or event setup. Whether you are shooting on a classic EOS film body or a modern digital DSLR, this Canon provides the optical brilliance and electronic precision that defined the standard for high-end Speedlites.

Key Features

• Exceptional Guide Number of 55 (m/ISO 100 at 105mm), providing professional-level reach and power.

• Fully compatible with Canon E-TTL, offering advanced high-speed sync (FP flash) and FE lock.

• Integrated Wireless Master/Slave functionality, allowing you to trigger and control multiple flash groups.

• Versatile auto-zoom flash head covering a range from 24mm to 105mm, with a wide panel for 17mm.

• Full bounce and swivel capabilities (90° tilt and 270° swivel) for soft, indirect lighting.

• Robust build quality with an intuitive LCD interface and high-speed recycling.

• AF-assist beam to help the camera focus in total darkness or low-contrast situations.

Condition Report Good condition. Body: The Canon flash body shows normal signs of light use and minor cosmetic surface wear consistent with professional use. The battery compartment is clean and free from any corrosion. Sensor/Optics: The flash tube and fresnel lens are clear and deliver consistent light output without discoloration. Mechanics/Electronics: All electronic functions, including the zoom motor and wireless communication, have been fully tested and are working perfectly.

Specialist Note "The 550EX remains a workhorse in many professional bags for a simple reason: it is incredibly reliable. What I love about this model is its versatility—it was the first flash to really master the wireless Master/Slave relationship, and it still does it brilliantly today. It’s a rugged, honest piece of Japanese engineering that feels much more substantial than newer, lighter models. For anyone looking for a high-output flash that can command an entire lighting setup, this Canon is a top-tier choice."
