I know that this is a 3D printed proto and it could have been just left off in the pic when printing but it looks like they will not have an onboard flash.
I am not a avid user of an onboard flash by any means with the harshness but there are times when I want to use fill flash, at least it is there, instead of having to add my external just to get better look in the shade. I think no onboard is a negative to me. There are ways to use the onboard flash without harshness just by powering by a stop and get good pics. Anyone feel the same ?
