New Canon Speedlite 600EX II-RT Offers Powerful Continuous Lighting Performance
There's a new top-of-theline flash gun from Canon, and it's called the Speedlite 600EX II-RT. Compatible with a wide range of EOS cameras, this external flash features powerful performance, and improved continuous flash firing capabilities.
The 600EX II-RT covers a focal range of 20-200mm, and has a guide number of 60m at ISO 100. This effectively makes this flash gun one of the more powerful options in Canon's EOS system to date. Apart from that, it offers improvements of approximately 1.1 to 1.5 times when using AA batteries, or up to two times when used with the optional Compact Battery Pack CP-E4N.
Needless to say, it supports wireless functionality, including radio and optical transmission. Thanks to multiple flash system support, it is able to trigger up to five groups of compatible Canon Speedlite units.
There are also two less reasons to worry about durability, as the 600EX II-RT is dust- and waterresistant. As for functionality, it has an indicator to show when the flash is ready, and offers simplified button and dial operation.
