When I decided to upgrade my photography gear, the Canon Flash 600Ex Rt quickly caught my attention. After using it extensively, I want to share my experience and insights to help you decide if it’s the right flash for you.
Why I Chose the Canon Flash 600Ex Rt
I was looking for a powerful, reliable flash that could handle both on-camera and off-camera use. The 600Ex Rt offers a high guide number of 60 (at ISO 100, 200mm), which means it produces a strong burst of light, perfect for shooting in low-light conditions or large venues.
Key Features That Stood Out to Me
- Radio Transmission Wireless System: Unlike older models that relied on infrared, the 600Ex Rt uses radio signals for more reliable wireless flash triggering, even when the flash units aren’t in direct line of sight. This gave me much more freedom in positioning my flashes.
- High-Speed Sync (HSS): I often shoot portraits outdoors, and HSS allowed me to use fast shutter speeds to control ambient light and create a professional look.
- Tilt and Swivel Head: The flash head rotates and tilts, enabling me to bounce light off walls or ceilings for softer, more natural illumination.

Things to Consider Before Buying
- Price Point: It’s a premium flash, so it’s an investment. I weighed the cost against the features and performance, and for my needs, it was worth it.
- Battery Life: It uses AA batteries, which means I need to keep spare batteries handy during long sessions. Rechargeable batteries are a good option here.
- Weight: It’s a bit heavier compared to basic speedlights, so I recommend using it with a sturdy tripod or light stand when off-camera.
