This screen-grab is from footage from an NTSC Canon XL2 with the stock 20x lens zoomed about 1/3 (55mm?)and F1.8. notice that white glow around the dark V of the man's collar. What is causing this? I've noticed it in other footage from that camera, too. The 1st picture is slightly blown-up the 2nd isn't, and they are both taken from the same frame. I found this thread about lens aberration and the pictures look similar. http://forums.macrumors.com/showthread.php?t=1130581 Thank you in advance for your advise and knowledge!
