I have acanon 1ds mark 11,16.7 mp. Recently while shooting indoor sports I noted 1/4-1/2 frame of random photos there was a yellow discoloration along the long axis of the image.( It was not a dirty sensor or software proble w photoshop.) it was not on each image. It also could not be from a different temperature of light since 3 frames shot at the same time and only 1 frame had this. It was sort of like when the flash sync was off on film camrea. I was shooting asa 1000, and it was most apparent on the 85mm 1.2. It was not always on the same side of the image, it was sometimes in the middle. Anyone else seen this?It does not seem to happen on outdoor subjects. The lenses are clean as well.
