HVL-F20AM,...A question?

Jack, please don't take this the wrong way; but what most are saying is pretty much that it will be a waste of money that could have gone to a better flash.  For what you are wanting to do, you will be best served by getting a better flash.  It never hurts to have too much flash, as you can dial it down. But once you find yourself limited, you have to purchase again.  You may encounter times when you could use fill flash in the daytime or some other indoor venue in which  you will want flash (bounce or directly diffused )for  a subject for which the HVL-20 will be a very weak choice.  Hope this helps!
