My Buying Guide on Canon Speedlite 600Ex Rt
When I decided to upgrade my photography gear, the Canon Speedlite 600Ex Rt quickly caught my attention. If you’re considering this flash, here’s what I learned from my experience that might help you make an informed choice.
Why I Chose the Canon Speedlite 600Ex Rt
For me, having a reliable and powerful flash was essential. The 600Ex Rt offers a high guide number of 60 (at ISO 100, 200mm), which means it can illuminate subjects at a greater distance compared to many other flashes. This was perfect for the diverse shooting scenarios I encounter, from portraits to event photography.
Key Features That Stood Out
- Radio Transmission Wireless System: Unlike older models that rely solely on infrared signals, this Speedlite uses radio transmission for more reliable off-camera flash control. I found this especially useful in bright outdoor conditions or when obstacles block line of sight.
- Fast Recycling Time: The flash recycles quickly, so I didn’t miss any critical shots during fast-paced sessions.
- High-Speed Sync (HSS): This feature allowed me to use flash at shutter speeds faster than my camera’s native sync speed, helping me balance flash with bright backgrounds.
- Tilt and Swivel Head: I could easily bounce light off walls or ceilings for softer, more natural illumination.
- Compatibility: It works seamlessly with Canon’s E-TTL II metering system, making exposure adjustments smooth and accurate.
What to Consider Before Buying
- Price Point: The 600Ex Rt is on the higher end of the price spectrum for speedlites. I weighed the cost against my photography needs and decided it was a worthwhile investment.
- Size and Weight: It’s a bit bulkier and heavier than some other flashes. If you prioritize portability, this is something to keep in mind.
- Battery Life: It uses 4 AA batteries, and while the recycling is fast, I always carry spares to avoid downtime.
- Learning Curve: If you’re new to off-camera flash or wireless setups, it might take some time to fully utilize all features.
My Tips for Getting the Best Out of the 600Ex Rt
- Invest in quality rechargeable batteries to save money and reduce waste over time.
- Experiment with different bounce angles and modifiers to soften your light.
- Use the radio wireless function with multiple flashes to create complex lighting setups.
- Keep your firmware updated to benefit from Canon’s latest improvements.
Final Thoughts
After using the Canon Speedlite 600Ex Rt extensively, I can say it significantly enhanced my lighting capabilities. If you’re serious about photography and want a versatile, powerful flash that supports both on- and off-camera use, this model is worth considering. Just be prepared for the investment and some initial learning to unlock its full potential.
