My Buying Guides on Canon Flash 600Ex Rt
When I decided to upgrade my photography gear, the Canon Flash 600Ex Rt quickly caught my attention. If you’re considering this flash for your Canon camera, here’s what I learned from my experience to help you make an informed decision.
Why I Chose the Canon Flash 600Ex Rt
I needed a reliable and powerful flash that could keep up with my fast-paced shooting style. The 600Ex Rt offers a high guide number of 60 (at ISO 100), which means it delivers strong illumination even in challenging lighting conditions. Its compatibility with Canon’s E-TTL II metering system ensured my exposures were accurate without much manual adjustment.
Key Features That Stood Out to Me
- Radio Transmission Wireless System: Unlike older models that rely solely on optical signals, the 600Ex Rt uses radio transmission for wireless flash control. This gave me more freedom in positioning my flash units without worrying about line-of-sight issues.
- High-Speed Sync (HSS): Shooting outdoors with wide apertures often requires faster shutter speeds. With HSS, I could sync the flash up to 1/8000 sec, which was a game-changer for my portraits and action shots.
- Tilt and Swivel Head: The flash head can tilt and rotate, allowing me to bounce light off ceilings or walls for softer, more natural lighting effects.
- Durability and Build Quality: The flash feels solid and well-built in my hands, and it includes weather-resistant seals, which gave me confidence shooting in less-than-ideal weather.
What to Consider Before Buying
- Compatibility: Make sure your Canon camera supports E-TTL II metering and wireless flash control to take full advantage of the 600Ex Rt’s features.
- Price Point: This is a premium flash unit, so it’s a bit of an investment. I weighed the cost against my photography needs and decided it was worth it for the performance boost.
- Size and Weight: It’s a bit larger and heavier than some entry-level flashes. If you prefer lightweight gear for travel, keep this in mind.
- Additional Accessories: I also purchased extra batteries and a diffuser to maximize my shooting sessions without interruption.
Tips From My Experience
- Spend some time learning the radio wireless system setup—it’s straightforward but takes a little practice to master.
- Experiment with bounce flash techniques to avoid harsh shadows. The swivel head really helps here.
- Use the flash exposure compensation feature to fine-tune lighting on the fly.
- Carry spare batteries; the 600Ex Rt can consume power quickly during extended shoots.
Final Thoughts
The Canon Flash 600Ex Rt has significantly improved the quality of my photos, especially in low-light and creative lighting scenarios. If you’re serious about flash photography and shoot with Canon gear, this flash is definitely worth considering. Just be sure to evaluate your needs and budget to make the best choice for your setup.
