Canon Speedlite 600EX-RT

Complete with built-in radio transmission wireless functionality, the Speedlite 600EX-RT sits at the top of Canons on-camera E-TTL / E-TTL II compatible flash lineup with a powerful guide number of 197ft at ISO 100 and 200mm. This two-way 2.4 GHz radio system provides added reliability and a range up to 98.4ft among up to 5 groups with a total of 15 individual Speedlites. This system also does not need direct line-of-site like traditional optical-based transmission and will work through obstacles.

For added coverage and functionality, the flashs zoom head can reach from 20-200mm, with the option for wide 14mm coverage when the built-in diffusion panel is used. Also, the unit can tilt from -7 to +90° and rotate 180° either left or right for complete bounce capabilities. On the back of the 600EX-RT is a backlit dot-matrix LCD panel that displays the status and allows users to easily access and change settings. Additionally, the flash is durable with a redesigned contact construction and improved dust and water resistant sealing.

Other capabilities of the 600EX-RT include a stroboscopic mode as well as high-speed, first and second curtain sync settings for more control over your images final look. The flash is powered by 4 AA batteries which provide a recycle time of 0.1-5.5 seconds, though it does have a port for an optional external power pack. It comes with a color filter holder with case, a light orange filter, a dark orange filter, a mini stand, and a Speedlite case.

Canon ST-E3-RT

The Canon ST-E3-RT Speedlite Transmitter can help you take full advantage of all the features on Canons Speedlite 600EX-RT and 430EX III-RT flashes. The ST-E3-RT makes complex lighting setups simple by facilitating radio-controlled, two-way wireless transmission up to 98.4 feet away, among up to five groups or fifteen individual Speedlites. It has controls similar to the Speedlite 600EX-RT, including multiple flash metering options, and a variety of flash modes. Compact design with highly reliable construction combined with a clearly laid-out information panel and buttons with back lighting make this an indispensible tool for advanced professional flash photography. The ST-E3-RT represents the next generation in wireless flash systems.

Note: Because it does not have an optical transmission function, the Speedlite Transmitter ST-E3-RT is not compatible with earlier Speedlite models such as 580EX II.

Newly-designed wireless system uses 2-way radio wave communication for enhanced communication among master and slave units. Achieves a transmission distance of up to 98.4 feet (30 m), all at a 360 degree angle.

Up to 5 groups, or 15 individual flashes can be controlled via 1 transmitter.
