As a Canon top-of-the-line flash, the Speedlite 600EX-RT takes the best features from existing models and adds functionality for enhanced digital photography. The 600EX features a new wireless multiple flash system using radio wave communication that provides more precise control over as many as five groups of flashes. There's also more power, with a guide number of 197' (60 m) at ISO 100, a zoom flash head that covers a 20-200mm range. Compatible with the AF frame of all EOS cameras, the Speedlite 600EX-RT even works perfectly with the 61-Point High Density Reticular AF found in the EOS-1D X and the EOS 5D Mark III.
The 600EX-RT offers radio controlled, two-way wireless transmission up to 98.4 feet, among up to 5 groups with a total of 15 individual speedlites. Communicating on 2.4 GHz frequencies, it doesn't have the same directional limitations of traditional wireless optical transmitters. Where other wireless signals can be interrupted by physical obstacles, radio controlled systems excel. 15 transmission channels are available, selectable manually or automatically, and radio transmission IDs can be set to prevent misfiring in the event of signal interference on the same channel.
The included color filter holder and two orange color filters multiply your creative options--the holder is compatible with Canon as well as third-party gelatin filters. The 600EX offers several other improvements--it's been redesigned, with a metal hot shoe, improved dust- and water-resistance and body strength, plus the ability to control flash functions and settings from the camera menu. A dot matrix LCD panel and backlit button deliver much-improved visibility.
The flash supports all current versions of TTL, including evaluative E-TTL II. This is great for photographers who shoot high contrast or reflective subjects, like those encountered in wedding photography. Photographers can now capture every detail from the black of tuxedos to the white of wedding dresses. The 600EX-RT is compatible with all E-TTL II/E-TTL autoflash EOS DSLRs.
