Warning: Sigma Japan has posted a product advisory warning customers that when select Sigma lenses are attached to the Pentax K-1, a minor scratch to the camera's lens mount may be inflicted
When some SIGMA interchangeable lenses for Pentax mount are attached to the PENTAX K-1, the upper part of the mount can be scratched. This phenomenon is due to the interference with the shape of the upper part of the mount on the PENTAX K-1 camera body and it does not occur to any cameras other than PENTAX K-1.
