Hi everyone,
I wanted to let the photographers seeking info on using the Profoto B1 or D1 with the Canon 600EX-RT Speedlites that I found a solution.
When I first bought my Profoto B1 Kit I figured 2 lights were enough and if I needed a rim light or two I could use my Canon 600EX-RT’s in optical mode for the Profoto’s to trigger them. After much research I found that the Canon EX Speedlites are only compatible with each other in optical. (BUMMER).
I began researching to see if I can use a flash slave trigger to do the job and after much research including B&H and Adorama the reviews were stating that the products they bought did not work with the Canon EX series Speedlites.
I found this product on Amazon and ordered two of them:
I received them today (7-5-14) and immediately tested them on my Speedlite using the Profoto B1 to trigger it. It worked Flawlessly ! Not only did it work great but I was able to keep the Speedlite on radio mode (not slave mode) so I could control the flash output with my Canon ST-E3-RT Transmitter while handheld, and it worked seamlessly with no problems triggering the Speedlite at the power I set on the Transmitter manually.
Mind you, this is all working while I have the Profoto Air remote TTL-C on camera controlling the Profoto lights.
To give you an example, I have the Profoto lights at a power setting of 5 and the speedlites as rim lights at 1/4 power. I can lower or raise the profoto light power on camera from the remote and lower or raise the power on the speedlites from the Canon ST-E3-RT controller while holding it in my hand.
The only thing you can not do is turn the speedlite off with the remote. The flash slave trigger connected to the speedlite will still see the light and trigger the flash.
I’ve included photos of the product and packaging to help those searching for it a bit easier. Amazon still has the product as well.
