I protect my camera clear lense cover with a circle of screen protector. It's a little fiddley but worth it & doesn't seem to detract from the image quality though no doubt someone will claim it does. It is certainly going to be no worse than taking photos through a scratched cover. I had a screen protector (3 ply type) left over from my desire so I attached an 10mm circular sticky label to the front protective layer & carefully cut around it. Then attached a similar label to the rear layer slightly misaligned so I could use it to peel off the rear layer. Applied the screen protector to the camera window then peeled the front layer off using another misaligned label.
