Hello, I'm hoping to get some expedited feedback as to what might be causing the flare/streaking/star-type effect coming off the light sources in the attached pics. It's not usual and it ruined a bunch of shots from last nigh there in Mumbai. Parameters for most of the shots are 5dII, 24-105 at 24-70mm @ f4, no flash, ISO 1250-3200. I've done tons of this kind of shooting over the years and never experienced anything like this and it's freaking me out as the next 8 nights are all critical. At first I though camera movement given than some exposures were as slow as 1/10th, using the IS, but the subjects are sharp, there is no appreciable movement. The one with the balloons is a throwaway but shows the problem well, and its at a 125th Thanks very much for input.
