what about screen. My wife's priorities are IS, then a screen that doesn't pick up prints. She had the FX9 for a bit by Panasonic. She loved the fact that the screen had some coating that prevented prints and oily fingers from producing smudges. I know the Canon's have yet to have this film over their screens, but wondering what there is to protect it without being tacky. I recommended a screen cover, but she hated that.
