The only strange behavior I noticed is that when I shot a Christmas tree with the focus thrown way out (near side), the enormous circles of light had concentric rings inside them... they looked like the diffractive front glass of a lighthouse. Has anyone else seen this behavior?
That\'s pretty common. Somebody being sure about the reason may explain, I guess it has something to do with molded elements. I have seen it with the Sigma 30/1.4, Sigma 50/1.4, several other lenses including the Leica 90Cron AA.
Upper left corner. It is very seldom a problem. I say \"seldom\" as one never should say never. regards, /Jonas
