This revision improves continuous flash performance by 1.1-1.5x, or up to 2.0x with optional battery pack, simplifies the menu system for faster operation, and includes a specially designed bounce adapter, a hard color filter, and an updated soft case. The two-way 2.4 GHz radio system provides added reliability and a range up to 98.4' 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 flash's 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 II-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 II-RT include a stroboscopic mode as well as high-speed, first and second curtain sync settings for more control over your image's final look. The flash is powered by 4 AA batteries and has a port for an optional external power pack. The rated recycle time is 0.1-5.5 seconds, but can be sped up to 0.1-3.3 seconds in Quick Flash mode. It comes with a bounce adapter, a hard CTO filter set, a mini stand, and an updated soft case that holds the flash and accessories.Items Included: Canon Speedlite 600EX II-RT SBA-E3 Bounce Adapter for 600EX II-RT SCF-E3 Color Filter for 600EX II-RT Mini Stand Speedlite Case
