When I decided to upgrade my photography gear, the Canon Speedlite 600Ex II-RT quickly caught my attention. After using it extensively, I want to share my experience and guide you through the essential aspects to consider before making your purchase.
Understanding What the Canon Speedlite 600Ex II-RT Offers
From the start, I was impressed by its powerful flash output and reliable wireless capabilities. This speedlite is designed for Canon DSLR and mirrorless cameras, providing a strong guide number of 60 (ISO 100, meters), which means it can illuminate subjects even from a considerable distance.
Key Features That Stood Out to Me
- Radio Transmission Wireless System: Unlike older models relying on optical signals, this unit uses radio transmission, allowing me to trigger multiple flash units reliably even when they aren’t in direct line of sight.
- Fast Recycling Time: I noticed the flash recycles quickly, about 0.1 to 5.5 seconds depending on the power level, which is great for continuous shooting situations.
- Durability and Build Quality: It feels solid in hand, and the weather-resistant design gives me confidence to use it outdoors in varying conditions.
- Tilt and Swivel Head: The versatile flash head helps me bounce light off walls or ceilings easily, creating softer, more natural lighting effects.
- High-Speed Sync and Second-Curtain Sync: These advanced modes allow me to experiment creatively with motion and exposure.
What to Consider Before Buying
- Compatibility: Make sure your Canon camera supports E-TTL II metering and is compatible with the 600Ex II-RT’s wireless radio system. I checked my camera model first to avoid any surprises.
- Price Point: This is a premium flash unit, so be prepared for the investment. For me, the features justified the cost, but if you’re a casual shooter, a more basic flash might suffice.
- Size and Weight: It’s a bit bulkier compared to smaller speedlites, so if portability is your priority, consider how much gear you want to carry.
- Battery Type: It uses 4 AA batteries. I recommend rechargeable NiMH batteries to save money and reduce waste over time.
Accessories to Pair With Your Speedlite
To get the most out of the 600Ex II-RT, I paired it with a few extras:
- Diffusers and Bounce Cards: For softening harsh light.
- Flash Stands or Brackets: To position the flash off-camera.
- Extra Batteries: So I never run out during shoots.
