I have had the shadow problem before as well. And using the on body flash is useless because there's simply not enough room between the lens and the subject for the light to bounce in between.I have had that problem with shadows. Especially with subjects that can decide to up and leave. Sometime patience will not get you the shot, where a faster setup will. There are valid pros and cons about both methods. But mf focus is not always need with modern AF and lens. They do spot on jobs for hand held things like this, as this little guy flew away right after I took the shot.
