Description
The Canon Speedlite 600EX II-RT is a powerful E-TTL/E-TTL II on-camera flash with a guide number of 197ft at ISO 100, and a two-way 2.4GHz radio system for reliable wireless control up to 98.4ft — no line-of-sight required. Fresh 4-packs of AA batteries can be added to the hire.
Performance
Flash output improves 1.1x-1.5x or 2.0x with an external battery source, and recycle time runs 0.1-5.5 seconds (faster in Quick Flash mode). The zoom head covers 20-200mm, extending to 14mm coverage with the built-in diffusion panel, tilting -7° to +90° and rotating 180° either side for bounce work.
Control and Wireless
Up to 5 groups and 15 individual Speedlites can be controlled over radio, with optional optical transmission also available. A backlit LED panel shows status and settings, manual power runs 1/1 to 1/128 in 1/3-stop increments, and flash exposure compensation covers -3 to +3 EV. Improved dust and water sealing and contact construction round out the build.
