Not had this before myself but I think I have seen others report similar. Ive done a camera match of a building and the wireframe in the viewport is good but if I go to render a region of the viewport there is a substantial shift in the geomerty. The camera uses film offset (done with C4Ds camera calibrator tag) but ive not noticed issues before using offset. Thank god the full render frame renders out correct so this is just viewport.
