Folks,
I wanted to ask whether it is worth getting Speedlight.
I have a 5D MKII and naturally I do not have any pop up flash. I photograph portraits most of the time....or 50% of the time
I usually look for the natural light....but this is not always possible.
Is speedlight any good? When it is being used? Does it give a 3D light or a flat light?
I will purchase it only when I will see that I can't live with it....but the lack of a pop up flash made me think of it.
Thanks.
