Display keeps flashing - im sure this didnt happen before - ?

ANyway to fix it? is it a problem or normal?

You have the diffuser extended. If it isn't extended the flash thinks it is, so extend it once and retract it back to the head

Try pointing the flash back down at 90' and you should find that the display stops flashing

It is down to the ETTL - when you are pointing the flash to the ceiling it is warning you that it cant measure the required distances acuratley.

I'm sure someone will be along to confirm that or to prove me wrong
