I have seen a similar problem. I have a 565EXII and Canon 70D. On-camera, exposures are correct. Off-camera, with Sc (Canon Slave) mode, the usual result is gross overexposure. (> 3 stops). I haven't used another flash in optical EXIF slave mode to know whether the problem is with the flash or the camera. I have done a lot of tests, and observed the ...

If you are confident it's the flash tube that's bad, and are experienced in electronics, you can purchase a flash tube online and replace it. But, you will need the right knowledge, tools, and experience, and this is not as simple as, say, simply unplugging something and replacing it. Desoldering and soldering are involved. Discharging the capacitor in ...

All the testing that can be done has been, the ready light comes on - so it's charging ok, but with no output either through the commander mode or test button the guess at the flash tube is likely to be correct. Replacing a flash tube can be done but is absolutely not a job for the inexperienced. Even when turned off and with the batteries removed some ...

The first question to ask yourself is what kind of triggering system do you plan to use? CLS All the Yongnuo flashes with "EX" in their name can be used as a CLS slave. Dumb optical (S1/S2/SU-4) If you want to use dumb optical triggering, then all the current Yongnuo flashes have S1 and S2 "dumb" optical slave modes in them. manual radio triggers If ...

There are two different wireless systems used by Yongnuo (and other brands) to control (as opposed to simply firing) off-camera flash: Optical The on camera flash uses very short pulses of light to communicate with the receivers on the off camera flashes. Nikon's CLS and Canon's e-TTL system prior to the 600EX-RT use this system. Radio The on camera ...

Well it depends on how you wish for them to work in the first place. If you use your on camera flash to trigger them, then they will all work. If you use your existing flash with a cable, then you can use any additional ones as slaves, they will all work. If you use your existing flash on your camera, then this can work the same as the above. If you are ...

The 600EX-RT doesn't have a built-in dumb optical slave, it only understands the Canon wireless communication systems (optical and radio), which the Fuji doesn't speak. However, you could stick a dumb optical slave (such as the green-based Sonia optical triggers) on the PC port of the 600EX-RT, and trigger the flash manual-fashion if the Fuji's pop-up flash ...

You can buy cheap flash triggers that will trigger a flashgun via a PC cable or hotshoe adaptor. They just look for a flash of light, then trigger the connected flash. May be enough for you if you're using the Speedlite in manual mode and the Fuji is only generating one flash (any pre-flashes for red-eye reduction, or ettl metering would need to be disabled) ...

Doubtful. Canon's flash system uses a special set of pulses to communicate flash power information and sync details to the flashes in the system. It is unlikely that your Fuji camera implements support for this protocol and without that support, you can't remotely fire the 600EX-RT. There are other third party speedlights and strobes that you can get ...
