You can control the modeling light and ready beep with the X1.
Double click CH key to turn ON/OFF Modeling lamp.
C.Fn-07 – Turn remote flash beep Off / On – [– – = OFF] [on = ON]
And the XT32 does not have fewer functions. For one, it supports 16 groups. And some that don't need TTL will switch to it just for the interface.
Thanks, I know that I can control the modeling lamp and beep with the X1C as well.
In my opinion it just isn't really comfortable.
And the 16 groups feature is one that I deem to be easily implemented on the X1C, too.
But I might be wrong about that, since I don't know if there is new hardware needed or just software/firmware.
I am wondering if it would be easier adding TTL to the XT32 or adding the new groups to the X1C...
