Olympus Zuiko 50mm f1.4 versus f1.8

I already had to glue my rubber focus ring back on because it became loose. I don't think I will risk taking it back off right now; I will test to be sure the camera focus screen is correct but right now it looks like it is, and the amount of shots I shoot at infinity at large apertures is probably small enough that it's a tolerable problem for the most part.
