Hey i just found out that if you import the pics from the camera with ImageBrowser from the software that comes with the camera and you do info on the pic in ImageBrowser it will show you all of the info iPhoto won't...like ISO speed
So this means it's not the camera that doesn't pass on the info....just that if you use different software to import your pics you will lose some of the info on them. where if you import with ImageBrowser from canon it keeps all of the info.
I even used the pics ImageBrowser imported and draged them in iPhoto from my desktop and it still doesn't show the ISO speed like ImageBrowser does so this means that iPhoto doesn't import all of the data like ImageBrowser does. Which is a let down as iPhotos GUI is much better than ImageBrowser's :\
