This is probably a "silly" question but I am wondering about the benefits of an external flash unit over the built in camera flash, particularly for macro. I have a Canon 40D and Canon 7D (main camera). Cheaper flash units have a guide range lower than the Canon 7D (guide range 39). Question is, would I benefit? I am new to macro! Thanks in anticipation:t:
