Small problem with the lens
»www.canonrumors.com/2012/08/a-sm···o-issue/

The phenomenon shows up on Canon 5D Mk III and 1Dx cameras only. T4i and 7D bodies with firmware upgrade do NOT do this, nor do any other older cameras we could test.

The Sigma 180 OS and Sigma 150 OS macro lenses both show the effect and it’s identical. No other Sigma lenses that we stock showed the effect, nor did any Tamron or Tokina lenses. Obviously I can’t test what we don’t carry.

If you turn off Illumination Correction in the menu the effect goes away. To repeat, though, Illumination Correction in the 7D and T4i, on or off, doesn’t cause the effect.
