I use a 17-35 on a mkll soon to be a mklll and it is fine
Quite a bit dearer that lens must be a sigma issue lol
If the Sigma lens you have is this one then it's not supposed to work. It's a Sigma "DC" lens which means it's designed to fit cameras with APS-C sized sensors, e.g. the Canon 1.6x crop and the Nikon 1.5x crop.
Any Canon "EF" lens or Sigma "DG" lens should work.
