Cannot get Nissin MF18 Macro ring flash to fire on EOS 90D

[melwilliams]

Hi everyone,

I have a Canon 90D and have attached a Nissin MF18 macro ring flash. When a take a photo I cannot get the flash to fire. In menu > flash control, flash is enabled, but when I go into external flash settings, it says "This menu cannot be displayed. Incompatible flash or flash's power is turned off." The flash is compatible with this camera as I made sure of that before I bought it. Anyone have any tips?

Thanks!

Make sure flash firing isn't disabled. If it is the flash won't fire. Will the built in flash fire.

Will it fire in manual flash mode. Also check to see if flash firing can be disabled on the macro flash itself.

Flash is enabled. Built-in won't because it knows there's something connected to the hot shoe.

With the macro ring lite removed from the hot shoe will the built in flash fire. Also test the macro ring lite with the camera in full automatic (A+ Mode) to see if it will fire. A setting could be preventing you from firing the flash. Full Auto overrides all Custom Functions. With this we can see if a setting is set incorrectly.

Just to confirm you have the correct flash, does the flash have 4 contact pins or 5 contact pins?

Hello. 

I have the same equipment that you have (Canon EOS 90D (APS-C sensor) DSLR and Nissin Digital MF18 Ringflash for Canon).

I don't experience any problems with this pairing or getting it to fire (there maybe some features that don't function as a genuine Canon flash might, although I have not needed anything more than the Nissin's features and functions). I have used it in: TTL mode, Auto mode, Manual and Fine Macro modes.

If I can help with confirmation of my camera settings I'd be happy to help. Although you may have got your problem solved by now.

Good luck!
