G7xii vignetting

Have new G7xii which exhibits severe vignetting when shooting RAW at widest angle. This is not apparent when using "Quick Look" in Finder Mac OS X Sierra. But when I import the RAW file into Affinity Photo it is quite pronounced. Have others experienced this or do i have a lens problem?

Thanks for your thoughts.

Thanks for your help and yes, the acronym FOVCF is as you guessed.

Whether or not you see vignetting comes from the lens.  Vignetting in RAW files can be easily corrected in post-processing.  The Canon software should be able to correct it.  Third party software packages may not offer the support.for lens correction of a G7x II.

Thanks for clarification. So the FOVCF for the G7xii is 1.0 according to Canon. As I understand this there should be no cropping required. Is this right?

You've lost me.  What is FOVCF?  I am not familiar with your specification.  I do not understand your comment about cropping, either.

 

Another way to describe the relationship between focal length and image sensor size is AOV, Angle of View, something which I have not seen specified anywhere for the G7x Mark II.
