There are ~so~ many glass to air surfaces in one of these that it's a little more likely to flare than a more "sensible" prime lens. (The A 28-135/4 is similar in this regard, I'd say.) I even have a specular highlight starburst on a whale while using an A 35-105/3.5 - http://plg.komkon.org/a35-105_35/fl1.html . Ordinarily, I wouldn't be using such a lens for shooting whales, but I had just gotten the lens and was anxious to try it out, and I did have to work that day (whale watching), and I did have a very cooperative whale on one trip that day at a time that I happened to have that lens on one of the two bodies I was using.
