Canon 600ex RT error

Zienphotography — Tue, 27 Sep 2016 16:07:51 GMT

Hello,

We have a problem with the Canon 600 ex RT. The flash will go off at maximum power on 1/128 and 1/1.
We have tried serveral options but we can't solve it.

camera

5D mii
5D mii
6D

lens

16-35 2..8 + 4.0

We've got this problem with other flashes too. Doe you know what is the problem? Is it a regular problem?

Thank you in advance

Does the flash only output full power at 1/28 (odd number, shouldn't it be 1/32?) and no other (like 1/128 or 1/64)? If it produces nothing but full power for all settings, you have a big problem - a failure in circuitry that needs repair. This problem, while not prevalent, has been known to happen.

Certainly not a problem at 1/1. How are you triggering? Are you using any non-Canon equipment?

Which Camera?

Is it on camera or controlled remotely via optical or wireless? Have you tried to reset the settings? Are you in manual mode?

Those are E-TTL cameras. So unless you are going to set the flash power manually, the flash must be set to E-TTL as well. If you set it to TTL instead, it will always flash at full power.

Is the flash on the camera?

If the flash is in manual mode, and you cannot set the power, the flash is broken. If you are in a hurry call Canon, otherwise, buy Syl Arena's Speediliter's handbook.
