1d3 Exposure Strangeness

Ok, recently picked up a used 1d3 and have been extremely happy with it. I was shooting one of my sons' baseball games last night and noticed some strangeness happening with exposure and was wondering if anyone else has seen this and what might cause it.

Basically, I was shooting high speed bursts, 6400 ISO f2.8 1/800 AWB. Here are a series of 3 shots, you'll notice the exposure was changing on them:

Sodium Vapor lighting in the park? Your shutter speed is too fast for the lighting's duty cycle. It needs to be below 1/120s to capture the whole duty cycle, which of course is too slow to catch the action. You've just got to live with it and deal with it in post AFAIK. Lousy lighting.

^ Yep looks like cycling lights.

I was sort of wondering if it was that because the WB is also kind of whacky. At least I know it's not my camera.

And yes, it is HORRIBLE lighting at the park.


Thanks.
