What is Image Quality?

[anubis404]

I know this is quite a noob question and I should probably know the answer, but is sharpness the only thing that determines image quality on a lens?

Image quality is determined by a lot of things, sharpness, color, CA, etc...

Are you asking what produces good image quality images or good quality lenses? meh im even confusing myself...
