A reader asks:
I need your device on buying a secondary speed light . I currently have the canon 430 Ex 3 RT speedlite. I wish to purchase a second speedlite. Should I purchase the Canon flagship or should I buy a secondary 430 ? Are the 430’s more than enough for off camera work? Does it make sense to purchase a speedlite with more power? Any advice would be helpful ?
Well. “It depends”.
If your camera cannot use its pop-up flash to drive other flashes, then buy a 580/600, the flash that can be a “master”. The 430 can only be a “slave”.
Also, the 580/600 are more powerful. And they can rotate a full 360º, which is important when bouncing.
Or… you could do it all in manual mode with all remote flashes. using radio triggers like Pocketwizards. In that case, buy cheap flashes, like 430s or the even cheaper Yongnuo clones.
The choice is yours.
