Quick camera question

I've noticed 2 things that are a little bothersome, seeking opinions.

1)When you take a macro, there is a sever aberration on the edges, beyond just bokeh. It almost looks like a motion blur. Is this a manufacturer blemish? Or are others noticing this too?

2)Would scratches on the laser cover screw with the ability to focus? I'd think that the lasers might skew and get confused....

Thanks!
