<p>Why DO you ever use a flash? Think about it and you have the answer :)<br /><br />Harold,<br />I will mostly be using the flash w a diffuser on a wide angle lens. The whales here come up to the RIB quite often and there are often huge amounts of whales and Orcas.<br />I might try using the flash with a Better Beamer on my 80-400 too, we'll see how the weather conditions are.</p>
