Canon Speedlite 600EX-RT Flash is engineered to provide a new level of performance and reliability for professional flash photography with today’s most advanced DSLRs. With wireless two-way radio communication, the Speedlite 600 EX-RT allows photographers to expand their creativity using wireless speedlites with the reliability of radio triggering. The Speedlite 600EX-RT offers an expanded zoom range and a higher guide number, plus a number of improvements over its predecessor in both operation and feel. It features a new dot-matrix LCD panel for display of all pertinent shooting information, backlit controls plus an internal sound generator. Reliability is ensured with improved hot shoe contacts, improved flash head durability and the most comprehensive dust and water sealing system ever on a Canon Speedlite flash. A new color filter holder helps maintain accurate color in a variety of ambient light conditions.
To start: the new 600EX-RT Speedlite
Canon’s new top-of-the-line Speedlite replaces the previous Speedlite 580EX II in the line, and can be used with any EOS digital or even film camera. It brings a host of new features to photographers looking for an advanced Speedlite, above and beyond its built-in radio wireless capabilities. Used on-camera, it’s fully E-TTL compatible with all EOS digital SLRs and those Canon PowerShot models having a hot shoe on-camera. And, it’ll revert to off-the-film TTL if used with older 35mm film-based EOS cameras. So far from being exclusive to brand-new cameras such as the EOS 5D Mark III, the new Speedlite 600EX-RT can find a home in the camera bags of pretty much any EOS photographer.
Wireless, off-camera shooting with the Speedlite 600EX-RT
This new Speedlite remains fully backward-compatible for existing wireless E-TTL shooting. In other words, someone who already owns a Canon Speedlite system and shoots now with the current “optical” wireless E-TTL can bring the new Speedlite 600EX-RT Flash into their world and not miss a beat. The Speedlite 600EX-RT is completely compatible with Canon’s existing Wireless E-TTL, and can be mixed freely with flashes such as the 580EX II, previous 580EX or 550EX, 430EX II or 430EX, and/or the recent and less-expensive Speedlite 320EX or 270EX II. Used with optical Wireless E-TTL, it can work as an on-camera “master” unit, or off-camera “slave” unit, and as a slave unit, it can be freely mixed with other compatible Canon Speedlites.
So conventional, optical-based Wireless E-TTL – what Canon EOS users have worked with up to now – is entirely possible with the new Speedlite 600EX-RT.
But it also breaks ground for the entire photographic industry with its world’s-first, built-in radio control for Wireless E-TTL. This is entirely separate from, and in addition to, the just-mentioned “optical” Wireless E-TTL which it’s backward-compatible with.
The Speedlite 600EX-RT offers the user a choice of Wireless E-TTL methods: radio-based or optical. The two are entirely separate, and cannot be mixed and matched in the same set-up. For radio-based control, as of March, 2012, the only compatible flash gear are the Speedlite 600EX-RT and the accompanying Speedlite Transmitter ST-E3-RT (introduced along with the Speedlite 600EX-RT). Previous EOS Speedlites, like the 580EX II, are not compatible with Canon’s new radio-based systems. And, while it’s true that several third-party companies have developed accessories in the past few years to make Canon’s current Speedlites radio-compliant, these systems – again – cannot simply be mixed and matched with the new radio-based 600EX-RT Wireless E-TTL set-up.
Limits with the current “optical” wireless flash method
Perhaps the easiest way to begin this is to re-visit the inherent limits of optical-based wireless flash triggering. While the current optical-based system is an incredible piece of technology (Canon had the industry’s first truly wireless system for off-camera flash that allowed full TTL exposure control of up to three groups of flashes, when it launched Wireless E-TTL with the Speedlite 550EX and EOS 3 SLR camera, back in 1998), it has several important limitations that photographers have had to be cognizant of:
