Canon FD lenses or Sony Alpha lenses
 

Can somebody post a comparison review about the image quality between Canon FD lenses and Sony Alpha lenses on the NEX FS100.
It's just about the image quality. I have some very good (old ;-) ) Canon Fd lenses and the just work great on my new NEX-FS100. But before I start buying some new glass I want to know the difference between these two kind of lenses. I don't need autofocus, aperture control via the body. Just good glass on the camera.
Thanks for reading my post and for your feedback.
