Canon Speedlite 600EX II-RT with Power Pack Kit

Complete with built-in radio transmission wireless functionality, the Speedlite 600EX II-RT sits at the top of Canon's on-camera E-TTL / E-TTL II compatible flash lineup with a powerful guide number of 197' at ISO 100 and 200mm. 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.

Designed to give you plenty of power in a compact form factor, the Cyclone PocketMax PP-1000 from Bolt is a 5200mAh lithium-ion battery pack that weighs only 11.1 oz and can easily fit in your shirt or jeans pocket. It is compatible with a wide variety of flashes with high-voltage terminals, including Canon, Nikon, and Sony models. Providing up to 1000 full-power pops, the pack boasts recycling times as fast as 1.5 seconds even with most power-hungry units at full power, with this time considerably shrinking at lower power settings.

The Cyclone PP-1000 can be fully recharged in approximately 5.5 hours with its included 100-240 VAC charger, which features three adapters for use with US, UK, or EU standard wall plugs. Battery levels can be checked at any time thanks to three LED indicators and a battery indicator button, all found at the top. The unit also comes with a USB adapter for charging common gadgets such as your phone or tablet with the pack, and a custom-made carrying pouch with a belt loop so you can easily carry everything around.

Designed to be paired with the Cyclone PocketMax PP-1000, this Power Cable from Bolt allows you to connect your battery pack to select Canon, Bolt, or Nissin flashes. The round end of the cable goes onto the output port on your PocketMax, while the other end attaches to your flash unit. For a more secure connection, a locking ring on the cable can be turned clockwise to tighten the attachment.
