Sony A7RIV with 12 to 24mm lens. First shot at 12mm , second shot at 24mm. Both at f11, ISO 200. I am very pleased with this lens. I make big prints (20"x30"), and the lens is capable of rendering nice results at that enlargement. The dunes here bloom in autumn and are one of my favorite subjects. Age 86, and make seascapes, and the IBIS is a game changer, as I do not like carrying and using a tripod. I cannot comment as to how sharp the lens is at wide open apertures, as that is not the way I shoot (except in emergencies of no decent lighting)
