New camera - old lens. I shot these with the Sigma Art 35mm on my new Canon. It's not on every shot. has anyone see these before? Looks like it MIGHT be happening with shallow depth of field. Thoughts?

It is a common problem when using some 3rd party lenses. Just turn off the in-camera lens corrections.

1\$\begingroup\$ @JohnEye if I had to make a wild guess, the third party lens is returning an invalid/maximum/out-of-range value for something the camera is trying to read from it, making the camera apply a totally maxed out and incorrect "correction" to the image. \$\endgroup\$– mbrigApr 13, 2020 at 22:14
