And it is useless, if there is no radio inside.
Sorry, but I cannot leave this without comment.
Maybe it is useless for you if it has no RT inside.
But if it really has a guide number of 10 as the name indicates I wouldn't want/need this as an off camera flash because of its low flash power.
If it was a 270EX II (guide number 27) successor or even higher, I would say it should/could have an RT interface.
But a normal consumer, having a camera without a pop up flash would just want an on camera flash and gives a s*** on RT.
This on camera flash just has to be cheap and RT isn't cheap. For a normal consumer off camera flash is useless as he/she doesn't know how to use it.
So right now we don't have anything else but the name of that flash, we don't have technical data, we don't have a clue on which market or use case it is aiming at.
So why bashing at something you don't even really know?
This seems to me like a Pavlovian conditioning aiming at anything Canon is releasing.
