Last week a friend showed me his newly acquired 180mm/f2.8 Zuiko which he
had purchased for just over $300 CDN (~$200US). From the outside the lens
was like new. I was envious that I hadn't been in the camera store first.
Last night he showed me some astrophotos he had taken before he took the
lens back to the store. I have never seen anything like them. The stars
were football-shaped (astigmatism) and the brighter ones had blue halos
around them (chromatic aberration). Any ideas as to what is going on? I
have never even heard of such a bad lens!?
