Did your camera not come with software to convert RAW?
I can't believe I'm gonna say this, especially after all this hype about a new camera

I've been using it, but the download is a 30 day trial though. Also don't forget that different cameras use different types of RAW images. For example, my Canon uses a CR2 format rather than .raw. If you just do a google with the title freeware raw converting software, then this link would pop up http://www.photo-freeware.net/raw-shooter-essentials.php
Thank You Mike, should help as the supplied one I have tends to muck my computer up...
