The (lens tip) photo examples do show a bit weak performance for the longer focal lengths, sharpness wise. The ephotozine samples are useless (that happens often there?). The 400mm duck image shows at least an inadequacy of the OIS? And the life buoy station image the effects of diffraction (f22... really?).
