I have just switched from an old Canon 1Ds Mklll to a 5D MkIV.
Using the same Canon 17-40mm lens, I am having to constantly make manual distortion adjustments - usually dragging the Distortion slider to 100% - to correct the default lens profile.
This is something I never had to do with the 1Ds Mklll.
Anyone else find this with the 5D MkIV?
Is there something else I should be doing to avoid having to do this?
Thanks.
