For my gymnastics pics earlier in the day, I was using a lens hood. I was using the DA 50-135, 77 ltd, Sigma 70-200 HSM II, and was experiencing the same issue using all three lenses. For the sample pics I posted earlier, I was using the 50-135 without a hood.

Here are some pics from yesterday's gymnastics meet using the FA 77 with the hood extended. A huge variance between the first and second photos (looking at the skin tone and white wall in the background). The pics were taken less than a second apart.
