Misleading ‘flash button’
The button actually responsible for autofocus is mistaken for the flash trigger due to its proximity to the flash and lack of labelling.
Light in the viewfinder
The fact that a light is built into the viewfinder, which communicates the charging status of the flash is difficult for the user to understand.
This is because the user needs to know about the connection between the light and the flash trigger. The user must first find the light. This means that the user does not understand that the flash needs to be charged.
Multiple triggers
Due to the two available triggers, which also look different, it is difficult for the user to understand which trigger has which function.
