Overview

Being one of the former top grade models in the Canon flash lineup, the 550EX offers a solid build quality and a strong power output. Its manual mode covers a wide range of 8 f-stops. On the downside, there is neither a PC port nor an optical slave sensor, and recycling time is somewhat slow with 8 seconds at full power. Due to these reasons, it is unlikely to turn a Nikon shooter into a Canon flashgun afficionado, but it is an excellent choice within an existing Canon setup. Despite its age the 550 – like all EX series strobes – is also a TTL flash and can be used as master and slave in a modern wireless E-TTL (II) setup, and certainly on-camera too.
