most zuiko is good glass - certainly all mine are. I have one of these, and yes its good. BUT it's probably my least-used lens because it is both a little bit long and a little bit short for most situations I find. I much more often take the 75-150 zoom, which I think is vastly underated. You will find a few of my gallery shots with this. The 75-150 does seem to suffer from some sort of gassing causing a film/spots around the inside edge of the front element. Mine was bought with possible "fungus" and I have seen others simlarly described. However, it simply wiped off when I took the front element off - which is easy. Definitely not fungus. Both are really cheap so buy both. Probably find them at no more than /$30 each
