Hmm i dont have yet BD so i cant show what i mean

it's when you shoot something and on picture you see that half of the pic is in correct exp and other usual bottom one is under heavy shadow. it's really hard for me to explain since i'm struggle whit English

anyway let's say that popup flash will shot in ur lens that will give shadow yes ? so wat about DB wich is way bigger the popup.
All flash will always produce shadows. It is up to you as a photographer to take advantage of the physics of light so they will not show in an unflattering way. BD doesn't produce bad shadows if you don't let it.
