Re: Need Info on Flashes
"A friend suggested an external flash is much better then a flash that comes with the camera."
Should read, "a flash built into the camera," perhaps? It's true that an external flash is more versatile and will likely give better results than one built into the camera. The down side is that it will be bulkier and less convenient to carry. If all you need is a little fill flash most of the time, the built-in flash is probably better. Otherwise, the external flash might be better. It all depends on your needs. The external flash will enable bounce flash shots.
"What would be the benifit of purchasing this external flash?"
In my opinion, it would be more trouble that it's worth. If I were buying an external flash for this camera, I would buy a Canon flash which is designed to work with the camera's automatic circuitry. There are other brands which may offer some or all of this compatibility, but a Canon flash would be the wisest choice. If you know and understand how to use a manual flash, you could save a little money buying this flash, but, in my opinion, not enough to make it worthwhile.
