A lot of the top weddings are filmed on DSLR cameras. And they charge a arm and a leg. Their videos are some of the best with DSLR cameras, but you need to know how to use them to get the images to want. The newer models like the Canon 5D Mark 3 is much better now that you can monitor audio. Some people that do weddings like Panasonic Lumix GH2 because the auto focus is good for run and gunning. I think Canon is making video auto focus lens for the up coming T4i. Camcorders are simple to use. Nothing wrong with them but you are not going to get the amazing image out of them that a DSLR would give you.
