My Buying Guides on Flash Canon Speedlite 600Ex Ii Rt

When I decided to upgrade my photography gear, the Canon Speedlite 600EX II-RT caught my attention. After using it extensively, I want to share my experience and some key points to consider if you’re thinking about buying this flash.

Why I Chose the Canon Speedlite 600EX II-RT

I was looking for a powerful, reliable flash that could keep up with my Canon DSLR. The 600EX II-RT offers a high guide number of 60 (at ISO 100), which means it provides strong illumination even from a distance. Its fast recycling time helped me capture moments quickly without waiting for the flash to recharge.

Key Features That Stood Out to Me

  • Wireless Radio Transmission: Unlike older models that use optical triggering, this flash supports radio transmission, allowing me to position the flash off-camera without worrying about line of sight.
  • High-Speed Sync (HSS): I often shoot outdoors with wide apertures, and HSS lets me use shutter speeds faster than my camera’s sync speed, giving me more creative control.
  • Durability and Weather Resistance: The flash feels solid and is weather-sealed, which gave me confidence shooting in varied conditions.
  • Rotating and Tilting Head: The flexible flash head lets me bounce light easily for softer, more natural results.
  • Custom Functions and User Interface: The menus are intuitive, and I appreciated the customization options to tailor the flash’s behavior to my shooting style.

What to Consider Before Buying

  • Compatibility: Make sure your camera supports E-TTL II metering and is compatible with Canon’s RT wireless system to get the most out of this flash.
  • Size and Weight: It’s a bit bulkier and heavier than smaller speedlites, so consider how much gear you want to carry.
  • Price Point: The 600EX II-RT is a premium flash, so it’s an investment. I found it worthwhile for the performance boost, but if you’re on a budget, there are less expensive alternatives.
  • Battery Type: It uses AA batteries, so I recommend rechargeable NiMH batteries for cost efficiency and better performance.

Tips for Getting the Best Use Out of the 600EX II-RT

  • Invest in a set of off-camera triggers or use Canon’s built-in radio system to explore creative lighting setups.
  • Practice bouncing the flash off ceilings or walls to avoid harsh shadows.
  • Use the flash’s zoom head feature to match your lens focal length for optimal coverage and light distribution.
  • Regularly update your flash’s firmware to benefit from performance improvements.

Final Thoughts
