It seems that the SF26 is the only small flash that will work properly on a TTL basis with the Q2. So I have just bought one,. And so so far impressed by both its compactness and seeming functionality - although still early days.
I am looking for a lightweight compact TTL flash for use with my Q2, but am trying to understand which are compatible. I understand that the SF24D may be one option, but will the SF20 also work? Does anyone have any experience of either in use? The flash needs to be very compact and will only be for occasional use, primarily for fill-in basis so it needs to be TTL.
